93 force/merc 3 cyl black stator question

[todapark]

Last year I replaced my red stator with a black one and removed the stator adaptor. The boat ran fine but after sitting all winter I am back to a no spark at all condition. Does anyone know the resistance and voltage output values for the black stator? I have a single CDM switchbox which was replaced the year before the stator replacement. From the stator I get 512 ohms from the red wire to gnd and 27 ohms from the blue wire to ground. I get about 30 volts (using a non peak DVM) from the red wire to ground and zero volts from the blue wire to ground, I know the voltage values won't be exact by not using a DVA but should I see some voltage from the blue wire or is that the high speed coil? I'm leaning towards the switchbox being bad again but want to make sure. All help is appreciated. Also I get about 20 volts on the green/white wires from the stator to the rectifier and am getting trigger pulses. I did disconnect the black/yellow kill wires. I do have a rev limiter not sure how to test it though. Side note, thank god the engineers saved us all the trouble of replacing $3.00 points every 6 months by going to electronics, now I'm only spending about $200.00 a year replacing the electronics, and we call this progress!

Re: 93 force/merc 3 cyl black stator question

Is this a 70 hp, a 90 hp? or 75hp?<br />Why do I ask, because my wiring diagrams only show the grn/wht and wht/grn wires from the stator on the 75hp and 90hp, starting in 1996, and these motors had 3 cdm's. Earlier models had 1 switchbox. Perhaps the grn/wht wires are part of the stator upgrade.<br /><br />If it is a 1993 model, 70 or 90 hp, single switchbox: <br />The red wire from stator is the high speed charge coil.<br />The blue wire is the low speed coil.<br />With the upgraded stator, number 398-9873A24, resistance should be <br />0.1 - 0.5 ohms<br />using a DVA, you should get a 200 volt reading on the low speed (blue ) circuit. <br /><br />So it looks like a stator problem to me, but the stator problem could have been caused by a switchbox problem. The book says that if the stator values are not correct, replace it, then test the switchbox.<br /><br />I hope this helps.
