TEST PROCEDURE

1.Turn the engine off

2.Open the left side door, on the engine end of the machine.

WARNING: Secure the door in the open position using the door restraint system. If the machine does not have a door restraint system, remove the door or securely restrain it to prevent it from falling closed.

3.Check that the linkage attaching the solenoid to the engine speed control lever is properly aligned and in good condition. It is more important that the sole- noid linkage be more precisely aligned when in the high speed (de-energized position). See Figures F.1 and F.2.

Strobe-Tach Method:

1.Place a highly visible mark on the engine crankshaft pulley, or another rotating component connected to the engine crankshaft. See Figure F.1.

2.Connect the strobe-tach according to the manufac- turer’s instructions.

3.Start the engine and place the idle switch in the “HIGH IDLE” position. Apply a resistive load operat- ing the machine at 100% output (400 amps @ 36 volts) for about 30 minutes to get the machine up to operating temperature and the RPM to stabilize.

CAUTION: Do Not Short the Output Studs Together as a means of loading the machine. Serious damage can result that will not be covered by Warranty.

4.Direct the strobe-tach light on the highly visible mark that had been applied earlier and synchronize the light with the rotating mark. See the strobe-tach manufacturer’s instructions.
