This is a picture of the final installation showing the ARS-4 regulator, which replaced an ARS-2 and the Leece-Neville alternator.
*WARNING: We now know that installing a regulator in the engine compartment is NOT advised by Balmar. This particular regulator failed in less than three months. Balmar suggested the heat killed it. The second one also fried, and the third was moved outside the engine compartment and is likely still going.
Keep in mind that this install was done over 12 years ago back before we really knew about the heat issues with the potting epoxy on Balmar regulators.
I highly suggest calling Ron at Ronís Auto Electric (207)-549-5918 if you canít find a competent Leece-Neville dealer. He may ask you to send your old alternator in so he can match it up with a new one but with this article you should have the part number you need to order it from him, if your original alternator is a Motorola and you're installing it on a Universal M-25. I believe he will ship just about anywhere but I would call him to make sure.
The Leece-Neville model number for the external regulation plate cover is 114-307 & Ron stocks them.
