I would like to do some checks before pulling off the flywheel. I
suppose to do that I would have to make a flywheel anti rotation device
and a flywheel puller.
There is 1.1 ohms resistance across the yellow and yellow grey wire.
There are 3 wires coming out of the stator which wires do I put the
meter across to measure AC volts?
Also does anyone know what the lever is on the back of the primer valve
for? Also on thje primer valve is a cap and under cap is shroeder valve
what is that for?
Thanks for any help.

There are two different charging styles on a '92 50hp, depending on the
model number. Both have 3 wires coming from the stator, measure the
resistance between the 3. About 1.1 ohms sounds right, but one pair will
have a bit more and I can't remember which color ones. Also using a high
ohms scale, check each yellow wire to ground for any shorts.

One charging system is unregulated and has a 4 wire rectifier module which
is about
$60 US, the other has a finned regulator which is fairly expensive, over
$200 US.

You cannot test the regulator, just replace it if the stator is OK and all
the wiring and connections are good. The rectifier is checked with an
ohmmeter between each yellow lead and the case, and each yellow lead and the
red wire. Reverse the meter connection at each test to see if it is infinity
one way and low resistance the other.

The primer red lever is the manual "choke" which allows fuel into the intake
for starting. The lever should be inline with the black pimer body, all the
way clockwise. The valve is for injecting carbon cleaner or fogging oil into
the motor, saving you from removing the air box and doing it manually.

Good luck

Thank you very much for replying.
I have the 4 wire rectifier model , will do resistance checks tomorrow
if sober enough.
I cant run the motor until I get a water pump kit, which is a problem
being Xmas.
Bill is full clockwise primer fuel lever position primer on or off?

Thanks again for your help.
