Is mine bad?
I get 990 ohms, and every 7th kick gives me 4volts is all.

What SHOULD I have?

And, can these stator-coils be repaired?

Thanks a lot.

Come on, one of you gurus is bound to know this...

I haven't had any luck telling bad exciter coils from good ones with an ohm meter, they all read the same resistance (which I can't recall off the top of my head, 3.something ohms?). If the exciter coil is a large unit by itself on top of the stator plate, held on by two screws (Like an old 6v Honda stator setup.) then there is a replacement coil out there. If it's the Honda 12v style, I don't know of any cheap replacement.

Given the cheap cost of import stator plates, I'd just swap a new one in and see how it fares.

followup: yep, it was bad. Still unsure of the spec's for it, but a new one fixed the problem immediately and only had ~300 ohms resistance. (Got it off an old 1979 Yamaha DT175 before I spent $$ on ordering a new one.)
