On the way to work friday mourning the headlights just went off. So I pulled into a parking lot to see what I could find and they came back on So I went on to work. This mourning, The wife drives it to work and they go out again. Were do I start? Electrical problems are my worst nightmare. I am thinking ground or fuse. The schematics I have for an 80 zoop. I will check the rest of the lights when she gets home from work.

It is probably the headlight switch.  There is a circuit breaker of some sort built into them.  As they get older, they start kicking in the breaker as they get hot.  I have had this problem a couple times now.  You got any spares you can try?
