1990 4dr civic electrical problem?
Hello! This forum has helped me in the past, I guess it's my time to seek help instead of silently creeping to solve!
I have a 1990 4 door Honda civic with a B16A swap. I was driving yesterday and I guess the engine got a little hot, rad fan didn't kick in so it over heated bubbled over and now I have 0 electrical. Noting. Not even a dash light. I don't know if it caused a short somewhere. Since then I have moved the battery to the trunk, which I bought a brand new one and still nothing. I can't seem to find any blown fuses or loose connections anywhere. Maybe this has happened to someone. Any help would be appreciated. Thanks everyone!

Ya just bought one 3 volts, haha.. I guess the alternator is fried and not charging the battery (which is a brand new batt).. Thanks for the advice!

Make sure there is continuity from the big output post on the alternator back to the battery, or the alternator will be unable to charge the battery. If you have a stock setup (not a "big 3" upgrade which involves a new wire direct from the alternator to the battery), there is a fuse in the underhood fuse box in the circuit between the two big white wires. The alternator output post should have battery voltage at all times even with the engine not running.
Because of this, always disconnect the battery before working on the alternator. If you were to touch the output wire to ground with the battery connected, the fuse will blow.
