Charging problem on 67 Dodge D100

Post by wilmothcody »

This truck belongs to my Son and I have been trying to find his charging problem with no luck..Alt is good,Voltage Reg is new and is doing the same as the old one..There are 2 wires on his Alt..A large black and a green that runs to VR.I have pulled the dash cluster out and I have fire to both sides of the amp gauge..Hooked up a new amp gauge and still nothing..I have had 3 different alts and 2 regulators. The green wires runs between the Alt and the VR..Where does the other wire from the regulator go?I suspect to the ign..Could it be the ign switch itself? The back of the switch has ign 1 and ign 2..Also have unplugged the connections on the firewall where the harness's plug in..Those connections look good..Any ideas on where to look would sure be of much needed help..Thank You in advance..

I would think whatever one is powered up with ign to run position. Time for a test light/meter. :thinking

We don't know what you're working with in regards to the current wiring
in your D100. :thinking These harnesses can get kind of hacked up over
the course of 48 years. Take a look at the diagram in the link I've provided
to see if you can at least determine if the harness still resembled the
diagram.

Thank You..Got her charging..May not be the "Correct" way but I ran a wire from my Ballast Resistor that is constant hot when in run to the VR and its charging like a champ..Will give me time to trace down the bad wire an make changes or repair...
