Cranking Discharge Method 1Check battery voltage If voltage is greater than 12.5 volts, go to Step If voltage is less than
ampsAs the engine continues to run at 4500 RPM, the voltage should stabilize at approximately 14.5 volts and the alternator
output should begin to decrease If the engine's ammeter doesn't indicate the above, check stator condition before replacing
rectifier regulatorTachometer Circuit 1If the VRO fIno oil" warning signal is in question or if the boat's tachometer is
not working, test the tachometer circuit2Verify that all wiring and Amphenol connectors are in good condition3Set peak-reading
voltmeter to "POS" and "50"4Attach the meter red lead to terminal strip gray terminal and meter black lead to clean engine
ground f21 5With the engine running at 1000 RPM, the voltmeter should indicate volts If the voltmeter shows specified voltage,
go to Step If the voltmeter shows less than volts, go to Step If the voltmeter does not show voltage, replace the rectifierregu
