Have No Power help!

OK, if you don't have a manual, the post by abodyjoe has a 66 manual for download:

http://www.mymopar.com/downloads/servicemanuals/1966_Plymouth_Service_Manual.zip

Electrical starts page 189 (Your reader page, not what it says on the "paper")

Wiring diagram index 289

Valiant/ Barracuda diagrams start page 304

Also, at the bottom are the links for the reworked diagrams from MyMopar. Easier to use in some cases

If you look at diagram A, find the bulkhead connector on the left, "Z" is a big thick wire on the diagram feeding from your fuseable link. So this connection in the bulkhead connector is ONE (of several) that is prone to problems because it's a high current connection

"B" is another one, which connects to the alternator

Now if you look on diagram "A" find the ammeter down near the bottom of the page. Follow the black wire off to the right and notice that it is connected to some other wiring. THIS IS THE "in harness" splice which is a factory splice wrapped up somewhere in the under-dash harness, there at least two of these and THEY CAN FAIL.

Some other trouble points are the connections THEMSELVES for the ammeter, that is, the factory crimped eyelet ends. These can become heated and deteriorated internally. It is wise to clip these off if there is any hint, and put new crimped eyelets on, or if you are going to permanently do away with the ammeter, just "butt splice" them together.
