My 86 GL-10 EA82T 4x4 Wgn parking lights went out this morning. When the headlight switch is in the parking lights or headlight position then the parking lights don't turn on. Headlights, turn signals & brake lights work though. When I go to the "push & turn left" position on the headlight switch the parking lights all work. Is that a different circuit? Any ideas on the problem or what to check?

Heres another note, The stock radio is gone (gaping hole) and I was using the radio wiring connector to "steal" some power off the red contact (12v for ext mp3 player) and shorted it againt the black contact in the connector (spark), no power on the red contact after that but the fuse for the radio was still good (hopefully it was the radio connector). Could that somehow have been connected to parking light circuit? Does anyone has a schematic for the parking lamp circuit they could send me?

I don't have the schematic but that short you are talking about could be the culprit as the radio will dim and brighten with the running lamps.

 

also wiggle the rocker switch on top of the column you can have it sitting just right and they will not come on.

I found the problem, simple blown fuse. I thought I had checked them all but I obviously missed # 6, it was blown big time. New fuse installed and running lights are nice & happy.

 

PS The running lamp override is in the headlight switch on this model not on the steering column. Thanks for your input!

 

PSS A Wiring diagram would still be great!
