After a serious brain malfunction of reversing the connection from the regulator to alternator, this is the result. Luckily it appears so far that just the one wire between the starter and ignition was fried.

Matt,

As my screen name dictates, I have a 1962 FJ40 the original generator upgraded with a Alternator. I never had the correct plug for the Alternator until this week. While installing the new plug and replacing the wires, I connected the two wires backwards to the external regulator. And the end result was lots of smoke and at least one burned wire.

i am sorry to hear this ?

is there anything i can do to help ?



so you have a FEN alternator ?

and a 40010 Regulator ?


IG
F
E

F= Field

E= Earth

N= Neutral

IG =on the Regulator TAB = Ignition

@HelloKitty65 / kieth is a expert on the 1962 era trucks like you have , perhaps he can chime in ?


if it helps at all ill send you out one of these in the Mail tomorrow ?

no cost involved , i have a bucket full of them and would be happy to contribute to your speedy repair :)

Thanks Matt, that would really be helpful. I'm not sure at this point if any other damage happened or not. Just keeping my fingers crossed. I will PM you shortly.

Pulled the main burned wire going from the starter to the ignition yesterday. Notice something missing?
…like a fusible link?
