I did with my '73 J4000. It turned out to be a bad regulator that was fried by a missing battery negative to body ground. YMMV. From: tbmccall <tbmccall@xxxxxxxxx> To: amc-list@xxxxxxxxxxxxxxxxx Subject: [AMC-list] Alternator light Message-ID: <br1r8u1om0p4crypanmxcerj.1355752381984@xxxxxxxxxxxxxxxxx> Content-Type: text/plain; charset="utf-8" I did a full tune up on my 73 matador to include a new coil, voltage regulator, and alternator. Although the system was charging the alternator light was staying on all the time, even with the key off. I called the alternator help line and they said take it back and exchange it. Im waiting for the next new one. Hopefully this will solve the issue. Anyone else ever experience this problem? -------------- next part -------------- An HTML attachment was scrubbed...
