Evinrude not charging

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

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.

Hey, can't hurt to ask right? :>)

Have a good holiday - all the best to you and yours.

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.

Thanks for replying. 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.
