IML: Dome Light On Half Power W/O Switches Closed



I really think that this dome light issue is related to some kind of an electrical short circuit. It has been explained that this light comes on even if the doors and light switch are not activated. That means that the circuit is being completed someplace else. It has to be, or the light can't work. I know it sounds wierd, but this short might not be in the wiring to the light itself.
 
A simliar situation in my '48 Lincoln Continental resulted from a grounded wire under the dash. In this case, the dome light became brighter as I increased the engine RPMs. At one point, it would go out until the RPMs fell back down to that level. I haven't mentioned this previously because the car is six volt positive ground. Nonetheless, it takes a completed circuit to make the light come on. Once I found the short, the light functioned normally, and so did the rest of the car.

Hi John,

Thanks a lot for your kind suggestion!
I will check the fusebox then to see if something is wrong there.
Might well be the case, cause about the same time my dome light stays on
at half power my wiper motor stopped working...
Might be an coincidence, but who knows?

I will check out the fusebox this weekend!

Thanks,

Robert
