I called the shop and he said it sounded to him like the high side on my stator was bad he said if i brought it by he could test it can I test it at home I have a meter that measures voltage and ohms


thanks

You'll need an adapter for the meter... Click HERE for details on how to make one.

Before you go to the trouble making a dva, disconnect all the leads from
switchbox, rectifier, and ground. Check resistance from blue to ground
and red to ground and post up your #'s. I don't have my manual in front of
me but if noone's post up I'll list the normal ranges.

This subject has been done to death... Resistance is NOT a valid way to verify ignition system components.

I know it's not a thorough check without a direct voltage adapter but
if the resistance is out of spec on the high speed coils, he can tell with
his VOM. If they break down at a certain rpm range then yes he'll need
a DVA. I'd start with the ohm readings and if need be check while running
with a DVA. To each his own. I've found 2 bad V6 stators by ohm readings
alone. I was just trying to save the guy some time and effort. I do however
agree that you need DV readings to thoroughly check the ignition, thats
why I own one.

Stator #s 398-8778, 398-9710 high speed coils 75-90 ohms, low speed
3250-3650ohms. Does your motor cut out around 2000-2500rpms?

Re: how to test my stator ????

sorry I havent had the time to test that yet no cutting out but it did make a noise a few times kinda like I had it trimmed a little high but it was all the way down I also found after further inspection of my plugs it seems there is a piece of metal(aluminum??) on the end of my #1 plug touching the electrode could this have been my problem all along?

Oh dear.... That sounds like a piston has detonated. If so, an engine strip and rebulid is the only fix.

Or a broken reed... Sometimes you can see the damage through the plug hole but if not, borrow a bore scope and have a look. achris is right, it aint gonna be good considering your qualifying symptoms.
