Re: 1995 115 not charging

Id say almost certainly the rectifier. Check the DC volts at the red output wire. if it stays at battery volts then pretty much confirms it.

Any chance you connected the battery with reversed polarity ... that's instant death to a rectifier

The simple non regulated rectifiers are easy to test but the combined regulator and rectifier not so

battery volts stay the same at red wire. does anybody know what readings i should get from the other wires or how to test them ????. thanks in advance

Put an AC voltage tester on the gray tach wire; it should read at least 5 volts AC with the engine at fast idle.

Put the DC voltmeter on the battery; it should read higher with the engine running at fast idle than with it off.

You have not filled in anything for your location in your profile so have no idea whereabouts in the world you are

I get my stuff from Outboards direct but iBoats would be a good choice if you are in the USA.

I think if your tachometer is working you will almost certainly get the correct reading on the gray wire

Thanks for that. the grey tach wire goes to one of the yellow wires if i mesure the voltage between the 2 i get from 40v upwards depending on the revs. should i go between the grey and earth?

Gray to engine ground. If you put external voltage on the gray wire you will need a new rectifier for sure.
