im working on a 88 civic dx hatch, and i jus changed the rear main oil seal. put everything back, then tried to start it, but the battery had drained out and wasn't starting. the engine was cranking however. so my friend tried his battery, but we accidentally inverted the battery terminals and connected them. there was a big spark and the main 60 amp fuse went out. so we connected the battery the right way, then we got another 60 amp fuse and as soon as we connected it, it blew. then we disconnected the battery, put the fuse in first, then reconnected the battery, which blew the fuse again.

what could be the problem, and where?

 

Unplug the alternator. Replace the 60amp fuse, and see what happens. If the fuse holds, the diodes in the alternator are toast. Unlee you're lucky, you may find there may be other things that don't work after you get the main fuse problem solved.

 

Blowing Fuses huh?.. Wanna try another??..

The only way you're ever going to blow a Fuse is because Power is reaching Ground before the Load.. And by putting a fuse in, you're pretty much turning on Current to a Load. And if there's a broken wire before the Load, Current will travel all the way to the broken wire and reach ground. And as it does that, the Fuse blows because there is nothing controlling the Current flowing through the wire..

So if you do what the Dude said about unplugging the Alternator and you find that it solves your problem.. I would have to say that your Voltage Regulator is dumping Current straight to Ground which would cause the 60A Fuse to blow...

But I could be wrong.. Good Luck..

 

anyone else?

little lost...could u break it down into simpler terms?

thanks

Unplug your Alternator and see if it blows a fuse.. If it does, you know that the problem is in the Alternator's circuit. Tell me how it goes..

 

i unplugged the alternator, and it started. so im guessing the alternator is fried. im trying to replace the alternator now, but the pivot bolt on the bottomside of the alternator is seriously stuck...got any ideas?

 

try to prevent it from moving from the front side... use a alligator socket or something... if not block it with a screwdriver..
