Wiring diagram

[ARCDEB]

Hi peeps can anybody help me? does anybody have a early 1982 sj410 wiring diagram must be the type with external voltage regulator, its got to be the one with 3 wire square plug on the alternator. There are plenty later ones with the built in regulators in the alternator but i can seen to find a early one, even the Haynes workshop manual does not cover they early type. Thanks in advance

The lj80 wiring diagram might work for what you need, they share the same alt and external voltage regulator.

You could always convert it to run the newer alternator with an internal regulator.

Thanks Scottie that's great, i don't suppose you know to convert to the new type with internal regulator ?

[ScottieJ]

You’ll just need to wire up the thick white wire to the + stud as usual.

IIRC the later jap ones have a type 1 style plug so

White-red that goes to the voltage reg is the warning light hook that up to L
And
Black-white to IG

The other wires aren’t needed. Make sure the white at the old voltage regulator plug is insulated though to avoid any shorts as that will be a permanent live.

Thanks for the reply's still having problems i think i am going to try and convert to later type alternator help needed

Do i have to disconnect the external regulator and leave loom plug?

[ScottieJ]

Yes you need to remove the external reg and then connect some of the wires from that plug to the connection on the back of the alternator as I explained in my last reply.

If you aren’t sure how to do what I explained in my last post then maybe it would be best to get help from an auto electrician or friend who is good with electrics.
