Circuits Diagnosis - Neutral Start Switch
Verify switch integrityThe neutral start switch is OPEN when the transaxle shifter is in R (reverse), D (drive), 3 (third gear), or 2 (second gear). When the transaxle selector is in P (park) or N (neutral) the switch closes allowing current to flow from the ignition switch to the starter solenoid. Current flows from the ignition switch, through the UHJB to the neutral start switch on circuit 6A (purple wire), through the switch to circuit 6X and on to the starter solenoid. Verify switch by back probing both terminals A and B at the Neutral Start Switch with shifter in Park and ignition in the "crank" position with a DVOM to ground. If no voltage is present at terminal A, inspect circuit 6A and 5A for poor connections or opens, starter relay, 30A ION 3 fuse (UHJB) and ignition switch.
