I sure hope your DUI distributor is/was not connected to the 18ga wire BY on the ALTERNATOR! That wire is way too small for that application. It should at least be connected to the 10ga BY wire that originally connected to your ignitor/coil...

The regulator fuse on a 1973 FJ40 is fuse 6 (Hazard fuse) not fuse 7 (Ignition) . It should be a Green/Red wire at the fuse panel. Inside the harness the White/Red wire is spliced to the Green/Red wire and goes out to the regulator three pin...

Excellent!

Well... If the alternator currently installed is an internally regulated alternator then the White #14 wire would go straight to the alternator as the excite wire. What is "power supply idling"? If you mean the truck does not want to idle, the...

If you can move it much at all it's worn. Any side to side movement will result in the points gap being all over the place while running. I think the old timers called that "points jitter".

The 1974 FJ40 Amp Meter shunt would be dificult to replace as it's part of the meter itself, not external like the 1979 and up amp meters. Great read: all things gauges Here is why you can run a high amp replacement alternator and not burn up...

1973 OEM Color Code for rear chassis wires Green = Park/Tail/License/Marker lights Green/Orange = Left Brake/Turn Green/Yellow = Right Brake/Turn Red/Blue = Reverse Light Real OEM tail lights have matching color wires, but aftermarket lights may...

Yes, I realize this is an old thread! I have measured several of these recently with a capacitance meter and just for the record that caps value runs from about 2600 uF to 3000 uF. Due to degradation over 25 years, I would assume that the...
