Forum rules and no-advertising policy

As a participant on this forum, it is your responsibility to know and follow our rules. Please read this message in its entirety.

Board Rules

1. You’re responsible for what you say.
As outlined in Section 230 of the Communications Decency Act, The Chronicle of the Horse and its affiliates, as well Jelsoft Enterprises Ltd., the developers of vBulletin, are not legally responsible for statements made in the forums.

This is a public forum viewed by a wide spectrum of people, so please be mindful of what you say and who might be reading it—details of personal disputes are likely better handled privately. While posters are legally responsible for their statements, the moderators may in their discretion remove or edit posts that violate these rules. Users have the ability to modify or delete their own messages after posting, but administrators generally will not delete posts, threads or accounts upon request.

Outright inflammatory, vulgar, harassing, malicious or otherwise inappropriate statements and criminal charges unsubstantiated by a reputable news source or legal documentation will not be tolerated and will be dealt with at the discretion of the moderators.

2. Conversations in horse-related forums should be horse-related.
The forums are a wonderful source of information and support for members of the horse community. While it’s understandably tempting to share information or search for input on other topics upon which members might have a similar level of knowledge, members must maintain the focus on horses.

3. Keep conversations productive, on topic and civil.
Discussion and disagreement are inevitable and encouraged; personal insults, diatribes and sniping comments are unproductive and unacceptable. Whether a subject is light-hearted or serious, keep posts focused on the current topic and of general interest to other participants of that thread. Utilize the private message feature or personal email where appropriate to address side topics or personal issues not related to the topic at large.

4. No advertising in the discussion forums.
Posts in the discussion forums directly or indirectly advertising horses, jobs, items or services for sale or wanted will be removed at the discretion of the moderators. Use of the private messaging feature or email addresses obtained through users’ profiles for unsolicited advertising is not permitted.

Company representatives may participate in discussions and answer questions about their products or services, or suggest their products on recent threads if they fulfill the criteria of a query. False "testimonials" provided by company affiliates posing as general consumers are not appropriate, and self-promotion of sales, ad campaigns, etc. through the discussion forums is not allowed.

Paid advertising is available on our classifieds site and through the purchase of banner ads. The tightly monitored Giveaways forum permits free listings of genuinely free horses and items available or wanted (on a limited basis). Items offered for trade are not allowed.

Advertising Policy Specifics
When in doubt of whether something you want to post constitutes advertising, please contact a moderator privately in advance for further clarification. Refer to the following points for general guidelines:

Horses – Only general discussion about the buying, leasing, selling and pricing of horses is permitted. If the post contains, or links to, the type of specific information typically found in a sales or wanted ad, and it’s related to a horse for sale, regardless of who’s selling it, it doesn’t belong in the discussion forums.

Stallions – Board members may ask for suggestions on breeding stallion recommendations. Stallion owners may reply to such queries by suggesting their own stallions, only if their horse fits the specific criteria of the original poster. Excessive promotion of a stallion by its owner or related parties is not permitted and will be addressed at the discretion of the moderators.

Services – Members may use the forums to ask for general recommendations of trainers, barns, shippers, farriers, etc., and other members may answer those requests by suggesting themselves or their company, if their services fulfill the specific criteria of the original post. Members may not solicit other members for business if it is not in response to a direct, genuine query.

Products – While members may ask for general opinions and suggestions on equipment, trailers, trucks, etc., they may not list the specific attributes for which they are in the market, as such posts serve as wanted ads.

Event Announcements – Members may post one notification of an upcoming event that may be of interest to fellow members, if the original poster does not benefit financially from the event. Such threads may not be “bumped” excessively. Premium members may post their own notices in the Event Announcements forum.

Charities/Rescues – Announcements for charitable or fundraising events can only be made for 501(c)(3) tax-exempt organizations. Special exceptions may be made, at the moderators’ discretion and direction, for board-related events or fundraising activities in extraordinary circumstances.

Occasional posts regarding horses available for adoption through IRS-registered horse rescue or placement programs are permitted in the appropriate forums, but these threads may be limited at the discretion of the moderators. Individuals may not advertise or make announcements for horses in need of rescue, placement or adoption unless the horse is available through a recognized rescue or placement agency or government-run entity or the thread fits the criteria for and is located in the Giveaways forum.

5. Do not post copyrighted photographs unless you have purchased that photo and have permission to do so.

6. Respect other members.
As members are often passionate about their beliefs and intentions can easily be misinterpreted in this type of environment, try to explore or resolve the inevitable disagreements that arise in the course of threads calmly and rationally.

If you see a post that you feel violates the rules of the board, please click the “alert” button (exclamation point inside of a triangle) in the bottom left corner of the post, which will alert ONLY the moderators to the post in question. They will then take whatever action, or no action, as deemed appropriate for the situation at their discretion. Do not air grievances regarding other posters or the moderators in the discussion forums.

Please be advised that adding another user to your “Ignore” list via your User Control Panel can be a useful tactic, which blocks posts and private messages by members whose commentary you’d rather avoid reading.

7. We have the right to reproduce statements made in the forums.
The Chronicle of the Horse may copy, quote, link to or otherwise reproduce posts, or portions of posts, in print or online for advertising or editorial purposes, if attributed to their original authors, and by posting in this forum, you hereby grant to The Chronicle of the Horse a perpetual, non-exclusive license under copyright and other rights, to do so.

8. We reserve the right to enforce and amend the rules.
The moderators may delete, edit, move or close any post or thread at any time, or refrain from doing any of the foregoing, in their discretion, and may suspend or revoke a user’s membership privileges at any time to maintain adherence to the rules and the general spirit of the forum.

Trailer wiring question

  • Trailer wiring question

    I recently bought a new trailer. It has 12-volt deep-cycle battery to power the interior lights and fans when it's not hooked to the truck. (This is not the same as the breakaway brake system; there's a separate battery for that).

    I assumed that the battery would also power the fans/lights when the truck was hooked up but not running, to avoid draining the truck battery, and then recharge from the truck when it runs. But looking at the wiring, it looks like that's not the case.

    There's a fusebox on the trailer between the connector cord and the rest of the trailer wiring. Here's a picture of it:

    http://dl.dropbox.com/u/12510845/fusebox.jpg

    The left side is the wire from the truck; the right side goes to the trailer wiring.

    Here's a circuit diagram:

    http://dl.dropbox.com/u/12510845/wiringchart.jpg

    The left/right sides are opposite from the wiring, but it seems pretty simple to understand.

    Note that the yellow wire from the truck accessory circuit is not connected to the trailer. There's a jumper between the truck hot/battery wire and the accessory terminal, so it looks like the hot/battery wire would feed both those circuits.

    To me, it seems like it would make more sense to disconnect the truck hot/battery wire, and feed both circuits with the accessory feed. When the accessory feed is not hot, they could both draw from the trailer battery. This could avoid draining the truck battery.

    On the other hand, I assume the trailer manufacturer had some reason for wiring it they way they did, and didn't just make a dumb mistake, so I'm a little reluctant to just change it myself.

    Does anybody have any ideas about why it's wired the way it is, or what might go wrong if I change it?

    Without an automatic converter, like in RV's, it's probably better to be hooked up separate like it is. They did that so they could have some lights when not hooked up to the truck. I guess the biggest concern is keeping the separate battery charged, but that should be easily figured out. I'd get one of the little automatic Battery Tenders to keep plugged in when you are not using the trailer.

      Ford trucks only power the aux circuit when the key is in the on position. This wiring bypasses that switch so power is always available from the truck.

      The 30 amp FUSE looks like a replacement that someone dropped in. The trailer wire doesn't "look" heavy enough for 30 amps. (10 gauge wire)

      If your truck powers the aux circuit without the ignition on, I would discard the jumper and connect the yellow aux wire.

      As for charging the trailer battery, look into a battery isolator to keep the trailer battery from discharging the truck.

        The fuses are all original. I bought this trailer new, so everything is just like it came from the factory. I don't know why they put that one 30 amp fuse in.

        I'm not even sure what, if anything, is on that circuit. I've got 2 exterior loading lights, interior lights in the trailer and tack room, and fans in the trailer and tack room. I haven't checked to see whether they're all one one circuit, or whether some are on the "hot" circuit and others on the aux.

        My truck is a Ford. I haven't actually tested to see if the aux circuit is powered with the key off, but if you say it isn't I'll believe you. But, with the battery on the trailer, I don't need power from the truck when the key is off. In fact, I'd prefer not to have it, because I don't want my truck battery draining when it's not running.

          Hey Matt - feel free to contact me with anything you might have a question about -
          The jump to the 30 amp fuse is because there is power coming in from your trailer battery & truck battery so the fuse is larger ( the jumper wire is a heavier gauge )- then it is jumped to the 20amp fuse that is the black hot wire that runs all your inside lights / fans / load lights - ( the yellow is not used )

          Your trailer battery will trickle charge, to help maintain its charge BUT it will only be sending power back from your truck as long as the truck alternator is indicating the truck battery needs a charge -

          it would take a very long trip to charge the trailer battery fully if it was low - so, do occasionally use a trickle charger on the trailer battery so it will not get too low or if the trailer has been sitting a while

          Thanks Much, Risa

            I think you just need to send me the trailer and get something less confusing.

              I don't know the specifics of my trailer wiring, but just for info: I have an accessory battery like yours which I love and use the lights, fans etc frequently. I use the trailer 3-4 times per week and pull with a Ford. I have never NEEDED to charge the accesory battery, but hook up a charger to it about once a year just to be safe.
