Actually it isn't the isolator, as I found out later.
The solenoid isn't receiving a switched 12V.... if I supply 12v the solenoid switches on and all terminals on the isolator show a high 13v reading.
I've got some wire chasing to do... I doubt it's something as nice and simple as a blown fuse.... none of the glass fuses in the fuse box are bad... there have been numerous pieces of wiring that have been done horribly, for instance: .....
Had similar problem - too many RV mechanics over the years -- too many wires with some leading nowhere. Relays put in place which didn't make sense etc.
I solved part of my problem by simplifying a few things. I knew the middle prong of the solenoid was supposed to be energized by turning the ignition key -- so I ran a wire from the solenoid through a grommet in the floor board to the radio fuse (piggy back fuse).
