8. Hold switch in START position. Test the following
connections for continuity: B to L, B to S, L to S.
There should be a reading of 0.3-1.0 ohms (continu-
ity) on the multi-meter (see Figures 13-15).
9. Check all other connection combinations for no conti-
nuity. B to L, B to S, and L to S should be the only
combinations that have continuity; all other connec-
tion combinations should have no continuity.
Replace a switch that does not meet all of the above test
results.
10. Reinstall the ignition switch and reattach the plug.

D. Test Power to Solenoid
1. Unplug the blue / white wire (A, Figure 16) from sole-
noid post 1.
2. Probe ground. Probe the blue / white wire plug.
3. Turn the ignition switch to START. The VOM should
show battery voltage. If not, recheck the key switch,
circuit breaker, and all connections.
