Outer Limits 4x4 Board

hj60 interior light works in door position but not the on position!
does anyone know where to start ?

The switch in the interior light, or the ground wire from the switch to the roof.

The light has a +12V constant, and the door switches complete the ground when they are open.

When you switch it to the ON position it grounds directly to the roof.

So if you have lights working for the DOOR mode, then your +12V upply is working, and the only problem could be the switch, or the ground from the switch to the roof.

I think there may not even be a ground wire, just a screw that goes through the light, contacting a metal section of the switch area, and into the metal of the roof which is the ground.

Check this screw first, you might need to pull the light out and clean the screw area etc on the roof.

cheers shadow, i cleaned up the terminals between the switch and circuit connections with a bit of 2000 wet & dry and bingo, we have light!

i only know this because i had trouble with mine about 5 years ago
