Temperature Gauge GM 3000-D, Testing with the Engine Off | Toro

Temperature Gauge (GM 3000–D)

The temperature gauge can be tested using a new gauge as a substitute or by the use of a DC voltage source and a variable resistance box.

150_F220_F

1.Connect the temperature gauge to the variable re sistance and DC voltage source (Fig. 34).

2.Adjust resistance until the gauge needle points to following test points on the gauge (Fig. 34):

A.At 220_F the resistance setting should be from 125.2 to 138.4 ohms.

B.At 150_F the resistance setting should be from 475 to 525 ohms.

3.Disconnect the voltage source, gauge, and variable resistance.

Oil Pressure Switch (GM 3000–D)

The switch is located on the left side of the engine block above the oil filter. It is a normally closed switch and opens with increasing oil pressure. The operating range for the switch is 6.1 to 8.4 PSI (0.42 to 0.58 Bar).

Testing with the Engine Off

1.Turn the ignition switch to ON. The oil pressure lamp should be on.

2.If the lamp does not come on in step 1 above no, dis connect the gray wire from the switch and ground it to the engine block.

A.If the lamp comes on the switch is bad.

B.If the lamp does not come on in step 2, check the indicating circuit (see Electrical Schematic (GM3000–D)).

Testing with the Engine On

1.If the lamp is on with the engine running, shut off the engine immediately.

2.Disconnect the gray wire from the switch.
