Good morning and thank for the comment. That was exactly what I though and I originally connected that way, but it doesn’t work.
Let me give some more background info into my jeep and then I will comment on the picture.
This is a M151 that I brought from Germany after my last tour there. It has a MWO for the jeeps at the EAO to install the new lights and turn signals. I am no sure if part of that MWO was to replace the generator for an alternator, but my jeep came already with an alternator, and it worked for some long time until it finally died last year. I got a brand-new alternator, the one on the picture, which I though it was a “1x1” replacement and I hook it up like that. It did not work and doesn’t charge. So, I started “investigating”. An old friend told me it needs to be “excited” to start charging and I must have missed a wire somewhere, but as you can see, my jeep only has 3 wires. A Battery, a negative, and a wire coming on the wire harness with a female connector.
Reding on different sites, I read one about somebody using an alternator from a HUMMER and they were talking that those alternators have a “pigtail” for some application that is no used on the 151, so I am wondering if this alternator is for a Hummer and that pigtail is no use and my wire harness wire should be connected to the small gold terminal next to the battery cable.
So, if anybody has any good ideas, just let me know. I got this alternator brand new on the box at a incredible price, so it should be good, but I do not have any idea for what application it may be, so being for a HUMMER can be a possibility.
