I was replacing my Alternator and forgot to disconnect the neg bat terminal.
Bonehead mistake for sure.
Anyway, was jostling new unit into place and heard buzzing and jerked it away from the area.
Only THEN did I disconnected the neg bat cable. Great.

So installed Alternator, fired up car with a multi meter attached to see if my charging circuit was working again.
Nope, just battery voltage.
Also, now most interior electronics are dead. Radio, clock, heater controls, power windows, turn signals, taillights,etc.
I checked all fuses with the multimeter in the engine bay and under the steering wheel, and they were all good.
Car starts, headlights and fogs work, done light, hazard lights work horn works.
Do you think I blew the main fuse 100a which I cannot figure out how to check.
Or if anyone has any ideas.

I’m going to get tha Alternator checked also at the auto parts place.
Thanks.

It looks blown. Take a close up photo. You can pop the clear plastic cover to get a better look. To replace it you need to unbolt it, it does not just pull out.

Thanks Steve, I thought it looked a little weird, like you said. Ok, beautiful, I’ll start with that. I was wondering if I could get that cover off, I’ll do that too , thanks.

In the manual, the fuse is listed as 100 amp ALT fuse.
That's the one you blew.
It's a bit of a pain to R&R.
Bolts on underneath the fuse box, you'll have to lift it up to see screws. May have to fully extract screws, too, as some fuses use ring terminals instead of 'U' shaped slide-on terms.

Thanks so much for your reply.
Ok, I will expect to go underneath fuse box and expect some struggling to remove it. thanks again.

Thanks a lot for the lesson! Now I can remember what not to do. Thank God there is still a fuse to bail you out.

Yeah, it was totally stupid mistake. I know, feel fortunate if that will bail me out. Probably deserve worse, but I’ll be happy if that’s all that’s required.
Note to self, disconnect the negative battery cable, for God’s sake.?

Seriously, when I disconnect the battery terminal clamp, I also cover the terminal with a big folded rag just in case the terminal is contacted by any live or grounded parts or tools!!!!

The plastic shipping covers on the terminals would seem to be good items to keep in your toolbox.

Yeah they spring back towards the terminal after you take them off.

Of course, if you forget to take them off ... ?

I unbotched the botched Alternator installation thanks to info from this board.
The 100a ALT fuse was blown, as spied by one of you folks, bought a replacement, installed it, which was a bit of a puzzle, bolted in... fuse box clips were a bit confusing, but hacked my way through it.

Turned on car, and presto I had 14 volts, and all the electronics were back on line ?

Thanks to all ??
