I have had this problem since I bought the car and think the old owner must have cut somthing on a radio install. The car is an 89 SC without the auto heads lights or keyless entry.
Nothing that FUSE 18 powers is working. I get no interior lights with either door open (checked both switches are good) but they do work with the head light switch. Power mirrors are out, map light etc all not working. I can get any one thing to work by jumping power to the power (green/yellow) wire.
What I don't understand is I get about 0.66 volts on the power wire. I jumped power to the map lights and they work but nothing else. I also jumped power to the power mirrors and got the same result, mirrors worked but nothing else. It seems to point to a junction where the power is distributed to all of the devices, but I can't explain the 0.66 volts.
Does anyone know where the power for this circuit braches out from. I don't want to rip into the dash with out a good idea of where to look.
I have the Helms shop manual but it doesn't give any electrical diagrams.
