Half my electrical went out all at once.

[Jimmy Van Hoose]

Have a 1974 Satellite Sebring Plus. Drove it to work and everything was fine. Got in it to go home and half my electrical wasnt working. Things not working are vaccum pump to brakes, gas gauge, aftermarket tach, turn signals, and blower. Things still working are speedometer, aftermarket oil pressure gauge, headlights, dome light. All the fuses are showing good, any ideas on what I should try next? Thanks

I would check for power coming in and out on each side of the fuse. Just because they look good doesn't mean they are. If that checks out good, start with an easy one like the vacuum pump, where does it get power from?

If that doesn't work check the bulkhead connectors famous for corrosion

Checked both sides of fuses with a tester they all worked. Ill look to see where pump is getting power from next. Thanks.

Just an update. The shop traced it to the horn relay and everything is working again for now.

It's always that oddball part you don't expect that throws knuckle balls at you. Glad it was simple.
