HELP! No power...?

the bulkhead connector in these old girls is problematic. Read up on the Mad Electrical stuff here:

The part about troubles with Mopar ammeters/ bulkhead connectors:

With "modern stuff" which can include much larger alternators, add-ons like electric fans, big stereos, or even hi-wattage, halogen headlights, the already over-rated bulkhead is suspect.

There are a number of things you can do. One is "feeding through" individual wires to eliminate the plug-connector especially for the high--amp connectors,

the other is to suck it in (I like ammeters) and bypass the ammeter, and run a bypass wire from the alternator to the big stud on the start relay.

these type spade connectors should NEVER have been used for the amperage they see in this service. I used to work on HVAC, including heat pumps and electric forced air handlers. These types of spade connectors are commonly used on heating elements, and at only 20A or so nominal current, they still give trouble.
