Greetings, I am at my wits end and decided to ask for help, cuz I need it. Let me start at the beginning. I acquired the FJ running as is and was always over amping, so much so that it killed two batteries. I decided to spend some time and study the issue. I discovered a crazy adaptation of a 4 wire Fors Voltage regulator and an amount of splicing in the wire harness that was INSANE and UNSAFE.
I decided to to gut the harness and start all over again, cuz damn! (Will attach pics) after some research…I have the original 3pin plus battery alternator which was bench Tested and passed with flying colors. We also are equipped with the double rectangular indicator dash light. Ebrake/no charge which calls for the 6 wire voltage regulator. I followed the schematic and the following happens.
The no charge light is always on even when running and charging, if I connect the “e” wire on the VR to the “E” (communal ground from alternator) the wire heats up super quick. I disconnect it and the VR “L” wire to the lamp as well but continues to overcharge even when disconnected.
Output at idle 13.64v
Output at full throttle 17.09v
Ammeter reading at idle -45amps
Ammeter reading at full throttle +infinity
Not sure if the ammeter os working properly. Have to tap it once in a blue to get it to read.
(Ammeter is simple only magnet no resistor)
Double checked the connections from alternator to Voltage Regulator.
Battery nut to ammeter to starter to battery
“F” alt to “F” vr
“N” alt to “N” vr ( what does “N” do?)
“E” alt to “E” vr (which burns the wire of o keep it connected)
On the vr side…..
Condenser/ignition (same post) to ignition
“L”vr (which is oddly soldered to the vr chasis) to the ground side of the the “no charge” indicator lamp (which keeps the light always on. (I keep in disconnected)
“B”vr to the battery (constant 12v feed)
Help me Obiwan Kenobi, you’re my only hope.
