705223 2008-09-15 00:09:00 I have a spare powerfull Japanese alternator (Denso)with 4 wires/connections. I want to fit it to my van which has a Lucas alternator with 2 wires, 1 to battery 1 to idiot light through ignition switch


On the Denso one big terminal is connected to battery with a nut on pretty happy with that one

Other three small connections I am not sure on
I guess one would be for a warning light, another for a voltage sense line but I cant work out what the 3 rd would be.
I cut the wires after the plug are the colours to an industry standard or do the car makers use colours willy nilly?
Although I scored the alternator from an abandoned vehicle (cant remember make or model) I dont want to smoke it by hooking up the wrong wires.
Thanks for any help

705225 2008-09-15 05:19:00 Some of the very early alternators used a 4-wire connection...they are quite obsolete, but they worked then and can be used again.

There is usually the BATT+, F or Field, S or Stator and I or Indicator for the light.

Here's some isometrics for you:

705227 2008-09-15 16:45:00 All of those diagrams have at least one 4-wire unit................

The ND typical is the last one...I just sent the others to confuse you a little...not really...but they show the redundancy of circuits, that's all.
