No Spark on 90 Merc 100 4 cyl

[ImNu2Boats]

Hi All I'm new to Iboats and am in need of some advice. I did a search but I didn't find an exact answer to my question.

I've done all the tests from the Seloc Manual for my motor and they indicate I have a bad stator and rectifier. I want to eliminate the rectifier from the circuit after I replace the stator so I can test the switch box. The replacement stator that I need say's it requires a rectifier.

I thought the rectifier was just there to charge the battery. Does anybody know why this stator requires it?

Thank you

James

they all require a rectifier and a battery - without a battery you will kill the electronics early and so you need the rectifier to convert ac voltage to dc - the rectifier also has one way diodes that prevent the electricity from backing up to the stator , change the trigger too while you have the flywheel off .
