Total electrical failure
I don't have very much experience at all with working on 4X4s but I've gotten a lot of enjoyment out of fixing up my '76 FJ40. Unfortunately, A few days ago I went out take a drive and it wouldn't start. The starter wouldn't turn, the headlights, dome light, and hazard flashers failed to light, and even the instruments had failed. The ammeter sits right at the 0 line halfway between -30 and +30 and doesn't move for anything. I tried to jump it and when that didn't work I tested the battery with a multimeter which showed adequate charge. I've gone through and checked all the fuses, the fusible link, and terminal connections to no avail. Once, after leaving it alone in frustration for a few hours, I went and tried it. Everything came on, but when I tried to start it, the starter clicked once and everything went back to being dead.
I really appreciate any advice you guys have, and I apologize in advance for being such a newb. I really looked all over, but couldn't find anything.
