I hope Mark chimes in here, I bet he knows the answer. I mentioned a couple of weeks again that my blue led on indicator panel was starting to glow when fridge not running. This started gradually over the last year and culminated with it being quite bright. This is a led I installed in panel about 13 years ago. It's a nice little mod, really helps to tell at a glance if fridge is running. That is if led working properly.

So I pulled the fridge and checked wiring connections. I added a ground wire between fridge and van chassis. This solved the problem.

Until about a week ago, and now again the led is starting to glow. I can't believe that it might be heat from the sun on van body transferring to combustion chamber that is the cause, but I keep forgetting to check at night or on cool days.

What could be the reason for this? Fridge stock except that 110 v system not connect, nor is the high amperage 12v feed to resistive heater.

Cheers,
