Charging issue

Dead battery. No rise in volts with engine running so charging system. Checked diode across rectifier, all good. Checked resistance on stator side and was good too. Started engine and checked AC output.. at idle 23v, 23v and 13v (&#x1f61f. Check at 5000 rpm 40v, 40v and 21v (&#x1f622
Pretty sure even the two "good" windings are not making enough AC and the third is for sure f*cked. No riding for this cat and the '51 off to the shop.

Your AC volts sound too low, aside from the obviously bad leg. I believe they should be north of 65 or so at 5K rpm's.

Garage
stator is easy. i did mine. just be careful on the new gasket, it has to go on dry EXCEPT for a dab of sealant where the case splits and one other area. i made the mistake of not using it before i had known and had to do the cover job over when i sprang a leak, also has to buy a 2nd gasket. sigh.......

lovin' my little torque monster.
