I continue to solve gremlins in my 85 Omni GLH and I'm getting exhausted. Little maintenance was done to the car so every time I turn around I seem to bump into another issue. Anyhow, enough venting... so my fuse box had 4 jumpers between circuits that I was able to troubleshoot down to just one final problem.
#4 and #8 are jumped (heater blower motor to fog lights). When the jumper is in place my car will crank and start and works fine. Also, the headlamps turn on when key is turned on. When the jumper is removed the car will not crank and the headlamps are off. The headlamps switch also doesn't work at turning the headlamps on or off they are just always on. However, the headlamp switch does actually work the park lights when the jumper is in place but doesn't at all when jumper out. The fog lights are both broken so don't work either although they are hooked up on the little switch under the dash.
I am not an electrical person so this has been a challenge figuring this out. I suspect that power is being back fed through the circuit by the jumper but would like to resolve this properly.
Anyhow, any ideas appreciated as I'm not sure where to look next. I do have all the service manuals to refer to and welcome any help or guidance.
I've attached a picture so you can what it looked like when I first started working on the fuse box.
Thanks!
