Take the
bulkhead connectors on the firewall all off
"very carefully" !!
rust & corrosion can wreak havoc in them & they can be very brittle also, take your time...
Clean all the connections very good, use what ever you need to,
to get the connections all clean as possibly !!
I used a little bronze wire brush, a pipe cleaners & a small piece of 220grit sandpaper,
then spray/clean it out
{use a aerosol electronics type cleaner that will be residue free}
& make sure to clean all the connections on both side...
Before reinstalling the bulkhead connectors, check them &
use a little dab of
Dielectric grease {use it on all electronics & grounds etc.}
use a little dab on each connection terminal...
Absolutely make sure & check your connections &
clean them
{use a dab of Dielectric grease on the connections}
when putting them back on the back of the Amp Gauge too,
check the wires going to & from, on the back of the Amp Gauge too,
make sure no cracked wire or burnt connections, that could ground out or short...
Good luck be safe, Bulkhead connections & Amp Gauge issue,
have caused some serious problems on many a Mopar's...
there's a site Mad Enterprises @
http://www.madelectrical.com/
in their electrical tech section they have some great info too...
the Amp Gauges can cause problems...
everything goes thru those bigger black wires under the dash,
that all goes thru the Amp Gauge, runs everything thru that one source....
you can also shorten the path for the charging circuit, ease some of the problems,
with a shorter 12 volt supplied current flow... less path to travel, far less resistance,
charging system will work better,
eases the load with less strain/draw on the under-dash wiring going thru the Amp Gauge...
You can run
{add, you don't need to remove/modify any of the OE wire} a 8ga. wire,
from the back of the alternator main output charging terminal the 1/4-20 threaded stud,
run the wire along/with your engine wire harness,
up-to the starter relay on the firewall by the bulkhead connectors, to the large 1/4-20 threaded stud
these will help even if your not having any issues
make sure you have a good/clean
{use Dielectric grease after getting a clean paint free connection, before reassembly} engine to body,
body to chassis & battery to chassis grounds
electronics will seek the shortest path of resistance, you really need good grounds,
good clean grounds will help to save/stave off some faulty old wiring issues,
add or replace grounds if necessary...
good luck & happy Moparing
