help with the fusible link wire smoking under the dash as i drive

Stop, and take deep breaths.
Now, what is the alt putting out? Over 14.5v, look at reg, and ground.
Next, bulkhead, then ammeter. They go south after years. (felt up in my dash one day, and got burnt-loose connection on ammeter, hot hot hot).
When I moved the battery to the trunk, I used madelectrical diagram( I, know, some people think it is gm, etc..). I bypassed the amp, soldering the wires together; grabbed the bulkhead wire from the alt, ran it to starter relay, installed a voltmeter (it tells you more), and the normal trunk stuff.
Works great. Go that that site. (I'll take the abuse, lol).
