Was driving at night about a week ago and heard a click (like a relay going out) in the dash and the dash lights went out, found out tonight (I don't drive the thing all that often, and being summer not much at night) that the tail lights also don't work including the trailer tail lights.

Anyone have any ideas on what is going on? I didn't find any bad fuses when I looked a little and would like to get this fixed.

Also there's a battery drain somewhere, if it isn't started about every 10 days it won't start, being a diesel it is a bit harder to start than a gasser but it also has two batteries to drain... connections are clean at the batteries, one may need the end changed which is one of the next steps on that

Main light switch is where the power comes from, Fuse #4
Dash lights also have fuse #10, but it is powered by fuse #4 when light switch is on
Both in cable fuse box

Trailer lights are done thru a relay in engine fuse box and trailer lights are powered by separate fuse, #4 in engine fuse box.
But the main light switch powers the relay to activate it

Looks like Main light switch would be where to start

My brother borrowed the thing last night, he looked into it and found the fuse blown (my guess is #4, but I'm roughly 2500 miles away from home as of this morning) and so far it's working... if it blows again I at least have a circuit to trace.

Thanks Ron!
