Been a while since I posted here! Have sold the EL (!) but have an EF/EL related question. I run an EF 100A alternator on my Suzuki Sierra but have just burnt through 2 in less than 2 weeks :x I'm not sure that I'm connecting the IG and L wires correctly to the Ford alternator and the regulator may therefore be chucking a hissy fit....

Can anyone confirm for me what the pinout on the alternator is? There are two pins, one closer to the +12V charge screw terminal (ie towards the top of the mounted alternator), one further away (bottom). The EF/EL's obviously just have a wiring loom plug that slips on. I'm doing the same using spade terminals and need to know whether the pin closes to the +12V charge terminal is (a) IG - exciter charge for the diodes or (b) L - charge light.

Cheers for any help :)

Had a quick look at the wiring diagram. Would appear that the 2 pins on the regulator are connected as you said. Pin IG should connect to the B+(12V) and the L pin should connect too the dash light (gnd when engine off and 12v when engine running). Maybe the following link to Mitsubishi Alternators would help.
