Corroded 7-pin no more
This was my solution which I did last year, so am pretty confident it is a good fix.
Your 7-pin trailer plug gets all corroded with green algae-looking mess then it will not work right. You have lights that do not light, brakes that do not work, battery that does not charge...
I simply put a circuit breaker between the plug and the camper battery. When in storage I can break the connection so the 7-pin plug has no voltage connected to it from the battery.
I used a 30 amp one like this circuit breaker
Link just for example.
Now there is no electrical potential at the plug during damp days and night. I have not experienced any corrosion.
With solar I often do not need to be connected to the alternator when driving, so can use this circuit breaker as a switch to choose also.
Cheers.
