Circuit is not putting out juice.
It did fine for years but not now.
I am pulling pwr and gnd both from the round plug at receiver.
Fuse checks out ok.
I use it to recharge a 4-battery bank in bed for 120v inverter.

Ideas?

 

Silly question, but did you put a multimeter on the 7-pin bargman connector on the truck? Is there juice there?

Yep, sure did.
No juice there.
Wire run looks good to the point it disappears.

 

Check the relay. That truck uses a relay to energize the charge circuit when the vehicle is running.

Where is the relay?

 

Should be in the underhood fusebox. Crack open the owners manual and there's a listing.

Cool, thanks. I looked there but must have missed it during initial troubleshooting.
