Howdy group just bought my first boat.

I am doing some checks before taking it, out its not charging the
battery.
Measure volts running same as not running.
Its tilt model 1992 50 hp, did checks for rectifier from this group, it
checks out ok. 12VDC at rectifier from battery red wire.
Are there some checks I can do on stator ie output or resistance
checks.
Also the auxillary is a not that old rude 2.3 hp is there any chance
these have a charging circuit.
Lucky I checked the water pump impellor it only had 1 leg on it!.
Thanks for any help you can give me.
Taking it to outboard shop isnt an option I would rather smash the
motor and get another one than taking it to ripoff o/b shops here in
nz.

Thanks

Chances are the 2.3 doesn't have a charging circuit. I think it's rope
pull, and I've never seen a starter motor for a motor that small.

Your 50 hp, probably/possibly has a bad stator under the flywheel.
they're not a heavy constructed winding, and sometimes, they won't
burn out, but there will be a pock mark in the enamel on a wire int he
winding itself, and wll corrode with humidity, and just get weak and
break. pretty simple to diagnose, I think that stator only has two
wires. which owuld be an input and an output. Its jsut one long wire
made into several coils. take an ohm meter and see if you have current
going though the leads,. if not? there's your problem.


Thats about all I know about it.

good luck.
