I was just given a 90 SC with about 97k miles. It has bad electrical gremlins and I'm asking for advice. Here's the short list of problems:
- Brake booster not getting power, therefore pedal won't go down, therefore key won't turn all the way back. This has the electric hydraulic pump, and I checked the 4 pin connector. It's only getting a fraction of a volt.
- Car sometimes cranks, sometimes does not. A screwdriver across the solenoid fires it right up.
- Tach, interior computer (change oil) panel dead, climate control dead, etc (saw these snap to life for about 3 seconds for no reason)
I'm thinking that step 1 might be to replace the main ground cable and clean any ground to chassis that I can find. There is a lot of corrosion on most of the aluminum under the hood.
Thoughts / suggestions?
