GROUND

PROCEDURE

1.Open the right side cover, on the radiator end of the SAE-400 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(s) or securely restrain them to prevent them from falling closed.

2.Locate the engine alternator (See Figure F.25 & Figure F.26)

#224

Chassis ground to the alternator flash/sense lead, (Lead #224 for cod 10856) (Lead #59 for codes 11199 and 11408) the meter should read 0 volts.

Run/stop switch on:

Chassis ground to the flash/sense lead, (Lead #224 for cod 10856) (Lead #59 for codes 11199 and 11408) the meter should read 11.5 to 12.9 Volts DC during first 30 seconds of operation. (This time may be 60 seconds on some models.)
