CHECKING SWITCHES

Check each switch for continuity with the pocket tester. If the continuity reading is incorrect, check the wiring connections and if necessary, replace the switch.
Never insert the tester probes into the coupler terminal slots "a". Always insert the probes from the opposite end of the coupler, taking care not to loosen or damage the leads.

• Before checking for continuity, set the pocket tester to "0" and to the "ohms x 1" range.
• When checking for continuity, switch back and forth between the switch positions a
   few times.
The switches and their terminal connections are illustrated as in the following example of the main switch.

The switch positions "a" are shown in the far left column and the switch lead colors "b" are shown in the top row.

The continuity (i. e., a closed circuit) between switch terminals at a given switch position is indicated by "O—O"-

There is continuity between the red and brown leads, and between the blue/yellow and blue leads when the switch is set to "ON".
CHECKING THE OIL LEVEL SWITCH
1. Drain:
    • Engine oil

2. Remove:
    • Oil level switch (from the crankcase)
3. Check:
    • Oil level switch resistance

      If out of specification -> Replace the oil level switch.      Oil level switch
Maximum level position resistance
     484-536 ohms
         
Minimum level position resistance
     114-126 ohms
      a. Connect the pocket tester (ohms x 100) to the oil level switch terminal as shown.

Minimum level position "A"
    • Positive tester probe -> connector (white) "1"
    • Negative tester probe -» body ground "2"

Maximum level position "B"
    • Positive tester probe -> connector (white) "1"
    • Negative tester probe -> body ground "2"
      b. Measure the oil level switch resistance.
