voltage regulator for a 1978 FJ40

[Bird Nerd]

I am trying to find a replacement voltage regulator for my 1978 FJ40 which was built in October of 1977. It has a solid state voltage regulator made by TRANSPO number IN568. I would like to replace both the alternator (Nippondenso 27020-61013) and the voltage regulator at the same time. I am having a hard time finding a solid state external regulator with the appropriate green plug etc. My research has turned up a Wagner built one (WO95-10) but, upon calling Wagner learned that they have discontinued the part. Any help would be very much appreciated.

@ToyotaMatt might have the period correct Voltage Regulator.

Do you mean that you might have the transpo IN568 voltage regulator?

 

[Bird Nerd]

Do you mean that you might have the TRANSPO IN568 voltage regulator in your possession ?

I don't but when I was going to replace my voltage regulator Matt was the only source I could find that had them for my 1/78.

Study the connector on the regulator closely - in '77 and '78, the voltage regulators changed dramatically. If Matt has it, it will be an OEM Toyota part, not an aftermarket one. My 7/78 FJ40 has the larger plug version with more pins than the earlier style.

I have a 2/79 fj40 with an external voltage regulator. @ToyotaMatt at VintageTEQ had what I was looking for. I just received my order.

3-wire green plug alternator 27020-61100
Large green oval plug Voltage regulator 27700-54040-84

Only observable differences are the cases are a little different and the location of the capacitor changed from the voltage regulator to on the alternator.

I have on I will sell for $15 plus shipping. It is correct solid state regulator in working condition. You will need to put your connecter on the color coded wires. Just let me know....Beckley

For clarification:
5/'78 to 7/'80 FJ40 uses 27700-24020-84 voltage regulator
8/'76 to 4/'78 FJ40 uses 27700-60100 voltage regulator

The 27700-24020-84 voltage regulator is still available from Toyota dealerships.
The 27700-60100 voltage regulator is discontinued and very hard to find.
