OK -- '92 Legacy Wagon. 235K miles. Love it -- most reliable vehicle I've ever owned. In the past week, it's started misbehaving. Driving home at night, the car will suddenly die -- tach goes to zero, dash lights and headlights go off, car starts to slow down -- and then comes back to life. Total outage is < 1 second -- just enough to freak you out. There's also an audible "click" from behind the dash, which I'm assuming is just a relay for the headlights or some other system. It seems pretty clear that it's electrical in nature, but it's a pretty major electrical issue to make everything go out -- it's as though I'm turning the key off and then on again. I was wondering if either the ignition switch or (if there is such a thing) a relay tied to the ignition is failing. However, if I really do turn the key off and on again, all the dash lights (fasten seat belt, etc) light up again (like when you're starting a car), and this isn't happening when the car "hiccups".
--If it were a bad coil pack/something in the engine electrical system, then the headlights/dash lights wouldn't go out.
--Anyone else had these symptoms? Other than a CV joint and regular maintenance (belts/hoses), this is the first time I've ever had the vehicle act up on me.
--Probably totally unrelated: my girlfriend mentioned that the ABS light occasionally comes on when she starts the car, and stays on for the duration of the drive, but the next time she starts the car, the light's out and stays out for weeks. Does the ABS light indicate anything other than ABS?
Thank you,
