Use the DC Shunt #19468 ( D , Figure 29) to avoid blowing the fuse in the test meter when testing the DC output of the 16 Amp system.
4 1 2 2 20 Amp DC Regulated Alternator The 20 Amp regulated alternator system provides AC current through two output leads to the regulator-rectifier. The regulator-rectifier converts the AC current to DC, an d regulates current to the battery. The charging rate will vary with engine RPM and temperature.
42 2 2 Figure 32 5. Rotate selector to DC volts position. 6. With the engine running at 3600 rpm, the output should be 3-20 amps. 7. If no or low output is found, be sure that the regulator-rectifier is grounded properly and all equipment connections are clean and secure.
4 3 2 2 ELECTRIC STARTERS Before assuming an electric starter requires service, check the engine for freedom of rotation by removing the spark plug and turning the crankshaft over by hand. Any belt, clutch, or other parasitic load will affect the starter cranking performance, so ensure their effects are minimized.
44 2 2 Figure 34 If the pinion gear sticks, clean the helix and gear with a mild solvent and compressed air. If the pinion continues to stick, replace the entire starter drive assembly. NOTE: Do not oil the pinion gear or helix. The starter motor clutch is designed to prevent damage from shock loads such as engine backfire.
