waiting for http://www.amprobe.com/Amprobe/usen/Multimeters/AM-500-Digital-Multimeter-Series/AM-520.htm?PID=74034 - with max/min peak measurement - hope it does the trick

OK have tried to get some readings but only succeed for the ohms measurements.

Both the stator and the timer base resistance measurements are within spec, I was able to locate all the wires so that seems ok.

However when trying to measure DVA I guess I did not get much of a reading unfortunately. After reading a bit more carefully I saw this in the CDI troubleshooting procedure:

"A Digital multimeter with peak voltage scale cannot be used without the DVA as the meter is expecting a 60 hertz signal where the outboard can have an equivalent frequency of over 1000 hertz." So guess I will not come any further without the dva adapter.

Guess my old meter would have been good enough with the DVA adapter. Nothing else to do than to get myself such an adapter.

It's a lot to learn - to be continued.

and here I am back again on the subject; i will try to make my own DVA adapter because they are very expensive here. Can anyone tell me if this way of making one will work for real? Any experience?

thanks,
