The problem is with the 92 Lx which has 3G alt upgrade mounted low on Vortech bracket. It has 4ga batt cable, with 200a breaker block, all proper harness plugs. It was a good install that’s been working well for several years. The altat the install time was a new 3g.
Pulled into the car show the other night and a person says, “there’s something glowing under your car”. Got out and looked under and saw the post and main batt cable glowing red hot.
The batt wire insulation is toasted for a length about 3” up the cable from the connection. Regulator wires and ground not showing and signs of heat. Just the positive post and wires connected to it. Checked the full length of remaining cable and wires including everything at the fuse block, starter solenoid and battery. No evidence of over heating anywhere but directly at the back of the alternator. Connections at the alternator were tight and corrosion free.
I’m trying to conclude where the heat started. Was it a wiring connection problem or an internal failure of the alternator itself?
Again, the setup had been performing well for several years including under heavy loads of hot weather with ac and electronic fans and what not
