Need Help - Leece Neville 165 amp alternator install in AZ

Thomas93E350ambulance · Apr 29, 2016

Hi I am a new 7.3 L IDI Ambulance owner and am having trouble hooking-up my wires to my alternator. I have a picture or two and was wondering exactly where I connect the Red/Light Green and White/black wires to (they are loomed together and bare). The Lg positive to the battery was obvious, but the other two are giving me trouble. Any help would be greatly appreciated.

The negative is through the frame and mounts of the alternator. I can't help with the wire color codes, sorry.

Thank you Dave, appreciate the info, any other information you might come across on the colored wires would help also

Field / Stator usually...just like says in diagram

yes, but they are not labeled on the alternator
all blank (see picture with bright letters, A, B, C...)

I'm thinking the stator is the post in my first picture labeled "D"..? That is what I seem to be understanding from the Leece-Nevile/prestolite pictures online...

I have nearly the same alternator, ground and pos. posts are obvious, D is ignition, that's all you need.

As a guess, "A" is your stator, and "D" is your field.
Connect a voltmeter to "A" - it should show some small AC voltage (if there is still some residual in the rotor).
Next, connect a wire from "D" to a 12v tail lamp and +12V. The alternator should have DC output.
