Re: Electrical 1990
Not likely to be of much help chasing a short as I don't know the 1990 electrical system at all. Agree with the alternator as a potential suspect though. Unless your battery is at full volts and still won't start; then might want to think about the starter. That clicking is the solenoid - if nothing else is happening either you don't have enough voltage to spin over (more likely) or your starter has gone bad. Hopefully someone who knows that model can chime in with more specific recommendations! Good luck - electrical faults are always simple after the fact but can be a real bear to figure out in the moment.
