Rectifier question.

[Asta]

I have a 1989 Mariner 75hp 3 cylinder. Rectifier #'s Old# 12082-A7... New# 194-5279<br /><br />The original rectifier went toes up and I have<br />Purchased the replacement, which is the third update since 89. There are 5 wires on the new<br />unit (2 red = Battery, 2 yellow = Alt..... one of them is high resistance and the other is around<br />56k ohms, and a gray = tach). There are 3 wires on the old unit (1 red = battery, 2 yellow = alt).<br />The question is...which yellow wire goes to which yellow wire, or does it<br />matter. Other than that... this should be a breeze.<br /><br />As for mounting the thing...the old rectifier is much larger than the new<br />one and no 2 bolt holes line up (there are three on the original. <br />Do I need to build an adapter plate or do they make one?<br /><br />Thanks for the help<br /><br />Michael

Re: Rectifier question.

The position of the yellow wires does not matter. The stator's job is to produce AC voltage. The rectifier changes that AC voltage to DC. You are replacing a rectifier with a rectifier/regulator. This will be a better fit(in my opinion) and provide a regulated 14.5v maximum power supply for your boat.

Hi dillagaf<br /><br />Thanks for the information.<br /><br />I am up and running again or at least not toasting my battery anymore.<br /><br />Cheers.<br /><br />Michael.

Re: Rectifier question.

paid $15 for the bracket to mount the new style<br />rectifier to my '70 1150 <br />rectifier was only $35! LOL
