Section 08 ELECTRICAL SYSTEM Subsection 03 (CHARGING SYSTEM)
Depending on battery charge, current reading should be approximately amperes for the 717 engine, 19 amperes for the 787 RFI engine and amperes for the 947 engineIf not, check magneto output prior to concluding that rectifier is faultyVoltage Test Proceed as follows: Start engine Connect multimeter to battery postsSet multimeter to Vdc scale Bring engine to approximately 5500 RPMIf multimeter reads over 15 volts, regulator is defectiveReplace itNOTE: If it is continually necessary to add distilled water to the battery, this indicates an over voltage situation, requiring replacement of the rectifier regulatorIf, on the other hand, the battery will not stay charged, the problem can be any of the charging circuit componentsIf these all check good, you would be accurate in assuming the problem to be in the rectifierregulatorGS, GTS and GTI Models If there is no charging at the battery with the preceding voltage test, the following test can also be performedGTS Model Open the electrical boxDisconnect the RED and BLACK wires of the rectifierregulatorGS and GTI Models Disconnect the connector housing of the rectifier regulatorUsing an appropriate terminal remover (Snap-on TT600-4), remove the RED and BLACK wires from the tab housing of the rectifierregulatorReconnect the connector housingGS, GTS and GTI Models Connect the positive probe of multimeter to the RED wire and the negative probe to the BLACK wireSet multimeter to Vdc scale
