I don't have a solution but a related question. I have been troubleshooting
the fridge relay under the seat and adding a second relay to handle
auxiliary battery charging. The blue wire is supplying charge voltage to the
relay but it will not switch over unless I put a test light on the terminal
for the red and white wire which is the other end of the relay trigger
circuit. As soon as I touch that terminal the test light lights, the relay
closes and supplies power to the fridge and the other relay trips and starts
charging the battery. I have checked and rechecked and replaced the relay's
as well as going back to the single relay configuration without luck. Any
ideas short af permanently wiring a test light??
