Silverado trailer charge line

On my Ford the charge line for the trailer was switched via a relay when the ignition was on to charge the trailers battery when driving.

On the Silverado, the charge line is on all the time. I would rather it go through a relay so I don't have to worry about discharging the trucks battery when stopped somewhere.

Is there any easy way to convert this? I'm sure someone has done it before

it's not to hard to do, you will need a relay that is controlled by the ignition.

i already had the relay because my truck came with the "snow plow prep package" don't ask, it's a wisconsin thing...

here is how i did mine http://www.airforums.com/forum...ead.php?t=3770

in that thread you will see the right hand post(post #2) on the fuse center, that is the one that powers the charge line. if you isolate the red wire going to the plug and add the relay you will be all set.

i'm sure you can find a "key on" fuse, or an accessory circuit in the same fuse center.

i'll go take a look on mine today...

Thanks for your efforts John.

I was looking thorugh my manual at the fuse box diagram. I compared it to the link you gave about rewiring your snow plow battery for your auxillary to your trailer.

My book shows the post #2 you used is the trailer brake feed. The book shows the auxilary feed is post #1.

I am concerned that you wired your trailer brakes up to your aux battery, and did not wire your aux battery to your charge line like you meant to.

You may want to double check it, or your wiring is different than mine. I have a 2001 Silverado 6.0L gas.

Just want to make sure you got it wired the way you meant to.

Let me know what you find.

Thanks.

our trucks must be wired different, when i was installing the aux wiring i checked to see that the brake controller worked with out the aux battery in the circuit. it does.

must be just a minor change from '00 to '01, or the plow package may have something to do with how the fuse center is set up.

either way, mine works great!

OK. Thats great.

I just got a little worried for you when I was reading mine. I was pretty sure you would have check it out anyway. But with your avatar picture you never know ;-)

Just kidding!

mine is 180 from yours, post one is brakes etc, 40 amp fuse. post two, trailer feed 30 amp fuse before i modified it.

i noticed directly center of the fuse panel there is a aux feed, 20 amp mini fuse, perhaps you could use that to power your relay.

as for my avatar, if you don't know what it is, don't touch it!

Very interesting discussion...

Tim, Now I'm wondering if my 04 is always charging the trailer battery. It would be harder to tell on our trailer with the solar panel (also always on, at least during the day), so I'm wondering if you checked with a meter or figured it out some other way? Are you concerned that it will drain the truck battery? Mine is a diesel with two batteries.
Thanks,
Ken

Ken. That is my concern. If I park some where with the truck connected both batteries will be operating the trailer. If the trailer battery goes bad or there is some unforseen load like a light left on, it could drain the trucks starting battery.

So, I have decided to put in a relay to only charge the trailer while the ignition is running. Camping world has a nice relay solenoid to do this. They are made to be on continuous to bridge batteries. (starting solenoids are not made for continuous on usage).

I have tested it with a volt meter so I know its hot all the time from the factory. At least on my 2001 Silverado.

That is weird. They do that just to mess with us

What do you bet the manual I am reading is wrong Thanks to your experience I will be double double checking it!

I'm going to tear into mine and see how it goes. I'll take some pics and post them here.

Got it done!

OK, here is what I ended up with. I installed a relay under the main fuse housing under the hood. There was a neat little spot for the relay so it is completely covered with the housing back on.

I found a fuse in the block to turn the new charge relay on only when the truck is running. This is designated as IGN E in the manual.

I used a relay that I had from another project but I would recommend the soleniod from camping world if you were to buy one. I still may replace this one for the camping world one.

One word of caution as John and I found out. Not all vehciles are wired the same. We have differences in our Silverados only a year apart. The pictures shown here are for my 2001. So double check your manual! AND test with a meter!

Now I can rest comfortably, knowing that I will not discharge my truck battery at an overnight stop if I don't unhook.
