AC output should be no less than 40VAC @3600
RPM.
If is found:
no or low output
• Replace stator.
9 Amp DC Outp ut Test
When testing regulator–rectifier for amperage
output, a 12 volt battery with a minimum charge
of 5 volts is required. There will be no charging
output if battery voltage is below 5 volts.
CAUTION: Connect test leads before starting
engine. Be sure connections are secure. If a test
lead vibrates loose while engine is running,
regulator-rectifier may be damaged.
1. Set meter. See Figure 11.
2. Attach RED test lead clip to DC output
