During last weekend's Peak District ride, my DR-Z's cranking speed got slower and slower during the day until it wouldn't start on the button halfway up Chapelgate.
At home on Sunday I charged the battery and ran the following tests:
So that would tend to suggest that the regulator/rectifier has gone west. Acquired a 'good' replacement off Fleabay, but it makes no difference.
Q: Have I got two dud regulator/rectifiers or is the problem elsewhere?

At home on Sunday I charged the battery and ran the following tests:
- Engine off, headlamp & tail-lamp on for 2 minutes, battery voltage 12.1v
- No significant current leakage from battery with all systems off
- Engine running, battery voltage 12.5v (should be 13.5-15.0v) indicating no charging
- All three generator coils showing around 1 ohm resistance (as per OE spec)
- Engine running, voltage across any two generator coils is over 80v AC (as specification)
- Continuity between regulator output wires and battery confirmed OK
So that would tend to suggest that the regulator/rectifier has gone west. Acquired a 'good' replacement off Fleabay, but it makes no difference.
