Greens master 3150 Page 5 - - 1 1 Electri cal System Electrical System Quick Checks Battery T est Use a multimeter to measure the voltage between th e battery terminals. Set the multimeter to the DC volts set ting. The batter y should be at a tempera ture of 60 o to 100 o F( 1 6 o to 38 o C).
Greensmaster 3150 Page 5 - - 12 Electrical S ystem Component T esting For accurate resistance and/or continuity checks, elec - trically disconne ct the component being tested from the circuit (e.g. unplug the ignition switch connector b efore doing a continuity c heck on the switch).
Greens master 3150 Page 5 - - 13 Electri cal System Hour Meter The hour m eter is locate d on the control pan el. Te s t i n g 1. Connect the positive (+) terminal of a 12 VDC source to the positive terminal of the h our meter . 2. Connect the negative ( - - ) terminal of the voltage source to the other terminal of the hou r meter .
Greensmaster 3150 Page 5 - - 14 Electrical S ystem Safety Relays Several safety rel ays are used on Greensmaster 3150 machines. The safety rela ys are identical, five (5) termi- nal relays tha t are used for cir cuit control.
Greens master 3150 Page 5 - - 15 Electri cal System Neutral and Mow Switche s The neutral and mow switches are used to determine when the functional co ntrol lever is in the NEUTRAL or MOW position. These switches are identical and are normally open reed switches.
Greensmaster 3150 Page 5 - - 16 Electrical S ystem Parking Brake Sensor The parking brake sensor is normally closed and opens when the operator sets the parking brake. If the function- al control lever is moved out of neutral (neutral switch opens) and the parking brake is set, the engine magneto will ground and the engine w ill stop.
Greens master 3150 Page 5 - - 17 Electri cal System Joystick Raise and Lower Switches The joystick raise and lower switches are located on the lift control mechanism. The rear switch is used to lower the reels and the front switch to raise them (Fig. 17).
Greensmaster 3150 Page 5 - - 18 Electrical S ystem Lower Reels Time Delay The lower ree ls time delay is a solid st ate timer used t o energize the lo wer relay (K5) long enough to make sure that the cutting units will low er fully when the joyst ick is moved.
Greens master 3150 Page 5 - - 19 Electri cal System Starter Sol enoid The starter solenoid used on the Greensm aster 3150 al- lows current flow from the ba ttery to the engine starter motor when energized. The starter soleno id is attached to the rear frame in front of the battery (Fig.
Greensmaster 3150 Page 5 - - 20 Electrical S ystem Solenoid V alve Co ils The Greensmaster h ydraulic control manifold uses sev- eral hydraulic solenoid val ve coils for system control. When the solenoid c oils are energized, hydraulic val ve shift occurs to control hydrau lic circuit flow .
Greens master 3150 Page 5 - - 21 Electri cal System Backlap Switch The backlap switch is a norma lly open ball s witch that is in the normal, open state when the backlap lever is in the mow position. When the backlap lever is in the backlap position, the switch closes.
Greensmaster 3150 Page 5 - - 22 Electrical S ystem Diodes The main wiring harness contains six (6) diodes. Diodes D2 and D3 are connected to the harness at separate locations.
Greens master 3150 Page 5 - - 23 Electri cal System Fusible Links The electrical sys tem on Greensmas ter 3150 machine s includes two (2) fusible links for machi ne circuit protec- tion. One of these fusible links is included in the main wire harness.

Greens master 3150 Page 5 - - 25 Electri cal System Leak Detector Al arm and Delay T imer The leak d etector alarm is used to notify the operator that a hydraulic leak has o ccurred. T o prevent the leak detector system from sounding false a larms during nor- mal operation, th e alarm circuit includes a one (1) sec- ond delay timer .
Greensmaster 3150 Page 5 - - 26 Electrical S ystem Leak Detector Float Sensor The leak detector float sensor cl osely monitors the hy- draulic fluid level in the main hydraulic ta nk. The sensor contacts are open when the float is in the raised position and oil level in the hydrau lic tank is co rrect.
