Last May I had a new alternator and battery installed, with a 1 year warranty
August I had to take the truck back and have them fix the alt again
The other day I noticed a smell of burning insulation (elect.) the truck quit charging and the wires on the bottom plug (two heavy gauge Battery wires and one smaller gauge starter wire) had melted and almost caught the alt. on fire.<O</O
I replaced the alt. as well as the plug and wires
It still will not charge. I have tried everything I know.
The battery is at full charge but only shows about one quarter charge on the gauge
It dies when you pull the negative post off battery while running
I am getting no advance on the gauge when I rev the engine
When this happens the Fusible Link "J" (14 GA-GRN) opens. On this type (2G) of Alternator you can buy a replaceable bridge with a stud on it and do away with the plug. You can also replace the Alternator with a type 3G from 1993.
This plug is a common failure on a 2G Alternator.
Fusible Link "J" (14 GA-GRN) is at the other end of two heavy gauge Battery wires at the Starter Solenoid on the Battery side.
