fusible link problems

[jade2ghost]

on my 440 the other day i was driving n my car stalled out, pulled over n seen that my fusible link wire was fried n on fire:angryfire: nt quiet sure wt would of caused it, nt to good with eletrical bt from wt i can see everything looks in place, id appreciate if any1 could shed sum light on the subject thanx

Sometimes, they just give it up. For no apparent reason other than they just got tired of doin their job. I would certainly back trace it though to be absolutely sure. Also too, you should replace it with more fusible link of the same gauge and quality.

check to see if where the fuse link goes into the bulkhead(at fire wall)has continuity to the body of the car.if it does,you have a shorted wire and need to find it.

AND..............check the bulkhead connector ITSELF. These are becoming a really bad problem for some guys. If the terminal inside gets loose/ corroded, it HEATS and this conducts heat to the (fuse) wiring next to it.

That is a great article with excellent photos and circuit diagrams. I highly recommend this fix for old Mopars. Also the addition and use of a battery switch can prevent a lot of nasty surprises. Remember, if you haven't completely re-wired your car, the wiring is probably 40 to 50+ yeas old. Way past it's intended service life.

I found those guys at MadElectrical.com years ago, great knowledgeable people, great parts, connectors, wiring products, automotive electronics supplies, relays, pre-wired connectors, schematics/diagrams too, be very carefully taking them apart they tend to really brittle, I also would highly suggest you use a brass or stainless, wire brush's, pipe cleaners or what ever you have to, to clean out both sides of all connection & when reinstalling add a dab of dielectric grease on all connection, it will help to keep moisture out & good conductivity... Also check all the connection, at the big black wire under the dash that goes to the "amp gauge" 1st & branches out everywhere, main power feed for everything, you can run a #8ga or #10ga wire from the main 12 volt charging 1/4" threaded post on the alternator, to the main large 5/16" threaded post on the starter relay on the firewall it will shorten the path for the charging system & relieve some of the load on all the bulkhead connections & especially the "amp gauge" connections that supply everything... Good luck, Electrical problems are a real bitch sometimes...

It's most likely the wire going to a defective amp gauge.You will also have to check the wire on the other side.Goes up the steering column to key and then to the amp gauge.
