Title: stator coil testing
Post by: billdn on March 21, 2017, 07:46:56 PM

electrics is not my thing, so I've been following Mr Haynes/Clymer. i tested the three yellow wires as it says but the minimum value should be 0.65 ish so if i'm getting more than that averaging 1.0 -1.5 am i OK or is the coil kaput?

Depends how accurate your ohm meter is.  It's difficult to measure low resistances accurately with a bog standard meter.   Your readings sound OK, it's not like they're open circuit or anything.

Thanks Mike. I'll invest in a lower range multimeter I think.

It's more helpful to test the ac output of the coils or, better still, check the charging current from the rectifier to the battery.   An ideal tool for testing current is a clamp meter.  Failing that,  checking the dc voltage when the engine is running.
