Hi Luke. I have just checked the Tech info on this alternator and it states that this alternator Must be able to excite itself with only a B+ wire connected.

The only problem is that i have tested one with only a B+ connected and it doesn't charge.


To prove if the alternator will work as a standard unit connect a warning light from B+ to the spare terminal. ( not to the DFM terminal thats got a wire in it ) just pull the plug out and use a speaker terminal onto the spade.
