    This is a genuine Leece-Neville 8MR 105-280 / 8RG2043 adjustable internal regulator. Please don't be fooled by the Chinese imitations of this regulator where the adjuster pot corrodes/fails in a matter of months.

    This simple two stage, BULK & ABSORPTION regulator can be used to replace your existing alternators stock non-adjustable regulator for better charging performance. It can be adjusted from 13.6V to 15.1V or anywhere in-between. For a $20.00 fee we can preset this regulator to your desired voltage before it leaves our shop.

    This regulator will fit any Leece-Neville, Motorola or Prestolite 8MR series alternator, as found on many marine engines, including Universal Diesel, Ford Lehman, Perkins etc.. This regulator will convert your existing alternator to "self excite". Installation is simple.

    NOTE: Your alternator must be an 8MR style with two AC / Stator taps for the two yellow wires.

    TIP: For increased voltage sensing performance the black and red regulator wires can be extended to the battery banks positive & negative terminals.
