Bulkhead connector removal - revealed wiring issue

[MRL777]

Figured I’d post a couple of pictures of the bulkhead connector removal and what I found.

Was having an intermittent starting issue.

Noticed a poor splice at the bulkhead connector at the blue ignition wire, so I removed the male side connectors and then the female base off of the firewall and pulled everything back out towards the engine compartment to examine. Easier than working under the dash!

Blue wire was toasted. I think I found my problem

That seems made by a short into the RUN ( Ign1 ) circuit. I would check the engine harness too same as the wiring down the tape from there up to ign switch.

Looooooong time ago I got broken the alternator brush ( on dual field ) grounding the RUN circuit and the blue wire cover got melt up to the cluster ( RUN circuit feeds the brake, oil light and voltage limiter on 3rd gen Chargers with standard cluster ). I didn't have fuse link on those days, just a regular jumper wire.

This is exactly why you bypass the amp gauge!

ABSOLUTELLY FALSE

the ammeter has NOTHING TO DO with what we are looking at. The blue wire circuit has NO RELATION with the ammeter wiring or ammeter itself.

and even an alt upgrade along with a bulkhead bypass or parallel path is allways something I advice to prevent charging network failures, This bulkhead is completelly healthy ( yet ) on this per what pictures show

Your so right nacho, Your blue wire is fried and has nothing to do with the amp gauge. Good luck in getting it working.

So I got under the dash to investigate and of course lots of electrical tape and this........notice bare spots on blue wire all the way to ignition switch

Time to investigate new wiring harnesses
