Alternator question:

When removing my old Alt I noticed the the ground wire was very hot with melted insulation around the connector.
(I had to move my truck from 1 part of the yard to another) I haven't driven it in almost 3 weeks.
Also the plastic around the ground connector on the Alt was melted. See comparison below.

Was this caused by the faulty Alt?
Looks like it could have been a potential fire.
Could it have been the massive corrosion on both connectors restricting the current?
I wire brushed the spade connector on the ground wire before installing the new Alt.

When I installed the new Alt the ground wire didn't get that hot.

I always have a fire extinguisher in the truck but I'm glad I haven't been driving it being afraid to get stuck somewhere.

I did a lot local test driving yesterday & no electrical or burning smells coming from the new Alt or wires.

If a connection overheats enough to melt, with no other damage, most of the time the fault is at the connection itself--corroded, loose, or shorting somewhere. No way to tell from a pic, though. Make sure you clean well the surface where the contact grounds TO.

Will do, thanks.

Installed & running good, no battery light & no burning smells.
