Ok I just replaced my alternator and volt reg today because it didn't start earlier. Got the parts from Autozone because I wanted something quick. Now I can't turn the car off! Had to unplug the distributor to shut it down for now. Did I plug it up wrong? The back of the new ALT doesn't look exactly like the old.

The old ALT just had a wire connected to the E and A locations but the new ALT has a BAT and two E locations for connections. I feel like such an idiot. I'm going to put the new ALT back an see if it helps.

Please give some insight, I need all the help I can get!

Sounds like you might have got an internally regulated alternator by mistake. I just read an account from the past, and a recent one on this forum, about "run-on" when an internally regulated alternator is connected to an external regulator.

E just stands for Earth. earth = ground

Hey thnx Zed. Looks like you hit the nail on the head with this one. I know I should've searched the forum first but I'm posting from a phone without wifi and I just wanted to get back out there to start taking the ALT off. Well I put the old ALT back on and everythings fine. I'm such an idiot. What a waste of time and energy. Gonna try n get my $$$ back tmrw then buy one from a more reputable Z dealer. Thnx again mate! Aye aye!!

Contact MSA and check for their Alternator Plug-In which allows you to use the internally regulated alternator with the earlier circuitry Z (which requires the external regulator).

Hey at least you know the car works we normally get the opposite on this site

Hey keep your old alternator they are easy to rebuild and it's not a bad idea to have an extra, I get parts from an alternator shop in Trenton NJ. Also make sure your external regulator is in good shape that can be a pain when not working properly. I wish you could get a rebuild kit from the autopart store but people just don't rebuild their stuff any more

No problem. Thanks for getting back with the solution. Now I know for sure what happens if you connect two regulators in series.

Thanks for the tips so far guys but I got another question for y'all (of course). So I want to go with the MSA upgrade Escanlon mentioned but the orig VR has a wire spliced. Will the MSA upgrade still be just as PNP as it's meant to be? Looks like the car has a few mickey mouse wirings going on. Here are some pics, hope someone can make sense of it all. I tried looking thru the FSM but that mess is to complicated for a simpleton like me.

God I hope I even uploaded these pics right. Had to get a photobucket acct just for this.
