Hey gang,
I am updating the towing setup behind the GV. I switched out to a 7-way plug and want to add a charge line to keep the Toad battery hot. Is there any harm if I tie into the outbound side of the battery isolator with a fused connection or should I run it all of the way up to the battery bank? Just don't want to fry the battery on the Toad with constant full voltage. Thoughts?
Thanks for the help.
Check the wires in the back where the trailer light connections are. I found a hot wire with ignition on mine.
Commercial kits from both BlueOx and Roadmaster include a 15 amp breaker that needs to be installed 6 to 8 inches from the toad battery.

Yes, no problem. Connecting to a battery side of the battery isolator will give you the same voltage as at the battery to which that lug of the isolator is connected.
That will have voltage at the toad all the time. Might be better to hook to the ignition solenoid or the hot with ignition wire in the loom at the rear.
Correct, unless a relay with "ignition hot" is used between the isolator and the toad. Under $15 for a good quality 40 amp relay.
I only charge the toad when engine is running and it's a good idea to have a fuse
on both ends of the charging wire.
