Okay...I have a '81 GL Wagon 1.8L 4WD w/ manual tranny. Here's the story again: Been having problems with the charging system...Autozone says the lifetime warrantied alternator went bad...replaced it and the battery. While doing so...I neglected to disconnect the pos battery cable and saw sparks from the alternator area...and when I did so I broke a fusible link on that ciruit. Now...with new fusible link the wagon starts but does not run for more than 2 minutes...the voltmeter idiot light comes on and shows only 10 volts. I am totally confused...hehe....duh buh duh...hehe. Got a good coil out of a '82 Hatchback but doesn't fit...wtf? Now I can't remember which wires go where...there are five of them on the small posts...and of course the main wire is obvious. I have a used VR but haven't tried it yet...the last time I got a new one from NAPA...it caught fire..so I put the old one back in...freaked me out..haha. I need to get the wagon up and running as cheap as possible...and then probably going to sell her...damn..oh well...don't crucify me....please. I need some input here folks.

Was the coil out of an 82 hatch a 1.6L (EA71)?? I recall those coils being smaller, or shorter or something than a 1.8 EA81.. or is it the other way around? does your 81 wagon have a 1.6, where as the hatch had the 1.8? well, either way, make sure the coil you got came from the right engine...

As far as your electrical, it sounds like when you sparked your alternator, and replaced the link, that you might have busted a diode in the alternator, or perhaps a voltage regulator. if autozone wont warranty it anymore, just go to the scrap yard and pull the diodes and regulator out of another alternator, put them in yours and see if that makes a difference.

Sounds like your having a tough time with your electrical stuff. most importantly, ALWAYS disconnect the battery, when even doing anything remotely related to electrical, and always make sure the ground cable is the first one removed, and the last one installed.

Another thing to look for, is when you burned a fuse link, you might have fried the wiring for the alternator. take apart the harness and make sure they are separate wires, and not a melted blob.

'81 is an external regulated model. SOunds like a bad regulator. But that doesn't explain the stop running condition. Although the fuel pump may run off of the charging curcuit. Kind of a failsafe, if the vehicle isn't running the fuel pump won't continue to run. I'd say replace the regulator and see if that cures both problems.
