Re: Recitifier test

A simple test would be to put a voltmeter on your battery when it's running. If it's showing 12 volts, your probably running off your battery, should be 14 volts, more if you don't have a voltage regulator.. Also, if you have a tach, it will show 0 rpms if the rectifier is blown.

Re: Recitifier test

go to radio-shack and ask for a "25 amp full wave bridge rectifier"<br /><br />they cost about 3 bucks, charge better and faster than OEM, and , well, they only cost 3 bucks, instead of 40.<br /><br />you can use them on ANY outboard that has a charging system. i have on on my 1976 OMC 115v4 right now

Re: Recitifier test

Myoutboards where is the recitifier on the motor. when the motor is running, the volt meter shows 12.45.[battery is fully charged, one year old] raised the rpms still 12.45<br /> Thanks, Dead eye

Re: Recitifier test

go to www*ishopmarine*com and look on the left hand menu, click the "parts list" link<br /><br />from there choose mercury and choose your motor and youll find it. save that page!youll need it again, unless you could cough up 25 bucks and get a stinkin' manual. i boats sells them<br /><br />look under the flywheel at the stator, follow the 2 yellow wires down untill it meets the rectifier. you should have 2 yellow wires coming in( ac voltage) and one red wire going out ( dc voltage)

Re: Recitifier test

not exactly. on the recitifer ( from radio shack) you will have 4 terminals:<br />2 for the AC voltage coming in<br />1 for the dc neg -<br />1 for the dc pos +<br />the 2 yellow wires from the stator are the AC coming in, the red from the old rectifier is the DC going iut, and you will need to rig up a new, short black wire, about 6 inches, to connect the ground, as the origonal was grounded through where it attaches to the block.<br /><br />mike<br /><br />peace
