Charging Systems - Honda Foreman Forums : Rubicon, Rincon, Rancher and Recon Forum

I use an 09 500 Foreman for work, we have GPS tracker units installed on two bikes. We think that the GPS units are draining the bateries when the bikes are not in use very much. I want to install a small aux battery in combination with a battery isolator but I need to know where to tap into the charging system. It needs to be between the alternator/generator and the battery. Where does this wire tap into the electrical system? Physical discription of location? Wiring diagram?
Thanks

hook pos to the pos bat post. neg to eng. use same cable as factory. 70's & 80's model ford camper speacial trucks have a solenoid to charge aux batt when running. hook one of these up inline on pos side. small wire to solenoid needs to be hooked up so its only hot when ignition is on. bike will start off factory batt and charge both when running. make sure mounting bracket of sol is grounded.

Thank you, I thought of using a solinoid after my boss handed me the isolater but I was not sure that it would work. I can hook that up easier.
Thanks

Interesting ---- I have a post on the Rubicon title asking how to do the same thing. I have a wiring diagram. There is a red wire that comes out to the harness on the requlator (under the rear right fender on a Rubi). According to the drawing this wire splits somewhere (I assume in the big harness). At this split one wire goes to feed the original battery and the other split goes to feed the key. So I believe the wire that goes to the battery needs to be cut and rewired to connect to the centre post on the battery isolator. The problem I have is this is still "my theory" on what to do and I don't want to cut the harness up if I am wrong. So I am looking for someone to say it is correct.
I thought of hooking the second battery in parallel with the original but I am afraid the extra resistance my be hard on the alternator - but I am not sure

no matter how you hook it up, the alt has to charge both. the idea with the solenoid or isolater is to hook your accesories up to the aux batt leaving a fully charged main batt to start the bike or vehicle and get you where you need to go. hooking the batts together will let you drain both. using the sol or iso lets you only drain one. they both still get recharged.

the isolator send a charge to only one battery at a time - switching back and forth depending on what battery needs a charge but does not charge both batteries at once - I don't see how the solenoid does this job
