Trailer Charger

[ChoppaNoob]

Hey,

Have any of you rigged up a battery tender in your trailer to charge your bike off of the truck battery. They sell a solar powered unit, but I'd like to wire something up off the trailer harness / running lights.

Dont want to damage anything, so thought I'd run it by yall. Guess I could just go check the amperage output with the truck running. If anyone knows of a product, please chime in.

Thanks !

This maybe ?

I don't know if they make a 12v input trickle charger but if they do you can just put in a cigaret lighter input connected to one of the hot wires. If not, you would need a 110 inverter to connect to a hot wire and then it would convert the 12v to 110.

I use a converter in my truck to power my laptop but if you can find a 12v trickle charger it would much better and cheaper.

more importantly that any of the previous questions, Why is the bike in the trailer?
Trailers are for break downs and storage.

You would have to have something to isolate the bike/trailer battery from the truck power when the truck lights were not on. Otherwise the bike would try to power the truck lights all the time. I think that part from O'Reilly does that, but it doesn't show enough information for me to judge. I would measure the voltage output of the truck lights to see if it is close to the charging voltage of your bike...

It probably would be a good idea to call Hopkins and ask them about their battery charger interface module :up:

If I were to do this I'd run a line from the battery (switched and fused) back to the trailer just for this purpose with enough power to charge a deep cycle marine battery or three. Use that to run an inverter then the standard trickle charger. Gives you some AC to use in the trailer when you need it as a benefit even when parked.

Brian....If your truck already has a 7 wire plug in, one of the wires will be 12v. On travel trailers they charge the battery for the RV while driving down the road. All you would need to do is wire a inverter to the hot wire and and then plug in the inverter. Here is a link to the standard wiring of a 7 wire plug

Thanks all,

I do have a 7 pin plug and one pin is hot all the time. I'm going to run that directly to a 12V breakaway charger. It's supposed to charge any battery up to 13V and then shutoff. I have an battery tender extension cable that I will splice to connect with the bike. I'll check it with multimeter to see how it does...

I've had problems with starting and stopping at rallies or short rides. Like to be able to charge the bike at night while in hotels. At home I just throw it on the trickle.

Hopefully she'll only be in there while I'm sleep !

Do not ever judge a person that trailers a bike. There are many circumstances that a person will have to trailer a bike and it does not make him any less of a biker than you. My wife was injured in a auto accident years ago and she can't ride my K9 for any long period of time so when I want to go to a bike weekend with her, it has to be trailered there so she is not in pain the entire ride. The bike is then ridden at the event to enjoy without her suffering for hundreds of miles to get there. Without her I will ride next to anybody for any distances.

Be careful about running a hot wire from your truck back and charging it off the car battery, that's like jumping a bike with jumper cables and that's a real quick way to fry an EHC!!! If you want to do this correctly, here's how to do it. On a 6 way round use the center post as a hot wire from your battery. On your trailer plug wire in a wire and run it to the inside of your trailer to a plug box. Does not matter what kind of plug but Tag the plug 12 volt. Now get a 12 volt voltage transformer. Home Depot sells them. Wire it with a matching male plug. This will generate 120 volt. Then plug in a trickle charger and clip it on to your battery while you go down the road it will charge your battery correctly.

Jonathan, don't you mean a 12 volt power inverter(not 12 volt transformer) to plug the trickle into?

Was having a Fu@$ing brain fart and could not think of the damn word INVERTER!!!!!! But yes!
