Instant loss of charging... car is now dead on road...

I wish I could help out Kid, Creed had the same thing happen to the bands Van a 1986, and he took the alt of my ramcharger in hopes to get them on the road to Little Rock Thursday night they had to rent a U-Haul trailer ....... fast forward to Friday evening and there was a plug with 4 wires that ran threw and the large wire in it was toasted and broke off.. This was not in the bulk head.. I hope this is corrected soon and this low voltage could have been your reason for miss firing at top end. Good luck and I hope to see this thread turn to a found it post soon
