Need some electrical help with my ‘68 Plymouth Valiant 100

Sorry to go back and forth, but got the three fuse head connectors that go into the fire way cleaned and used diaelectric grease on them and unfortunatley, the flickering is still happening. I had shard a photo of the fuse box earlier in this thread and you had reposted it with arrows. Is that red arrow pointing to the fusible link? It’s a black wire and red wire with a connection in between them next to the fuse heads.

The red arrow points to the actual fusible link.

This is what it looks like not attached to anything. (NOTE: there is a tab on the wire that says FUSABLE LINK) in your case the wire looks black and the tab looks yellow.

You need to understand that the entire wire is a fuse. the TAB is only there as an indicator.

I know it has been mentioned before but terminology means a lot.

This is The "Bulkhead" all the wires inside the car connect to it under the dash

These are the Bulkhead Connectors. all the wires in the engine compartment and the forward lighting are connected to them. They connect to the bulk head.

There are NO fuses in the Bulkhead EXCEPT the Fusable Link which is attached to it.



This is the "Fuse Block" it is mounted under the dash by the Emergency brake. SOME fuses are powered some are only powered when something is on
