• Loss of ground to the reverse switch.
6.
Top right rounded-shape: is a green wire.
•
Behavior: The green wire should always have continuity to ground.
•
Circuitry: The green wire leads to ground.
•
Interpretation: If this ground path is not good, there will probably be other ground-related issues with the
tractor: slow starter motor, slow battery charge, dim lights. All ground connections should be mechanically
secure and corrosion free.
7.
Bottom left square-shape: The red wire on the OCR plug carries battery voltage.
•
Behavior: With key switch in any of the run positions, D.C. battery voltage should show-up on a volt meter
when the red probe is touched to this terminal and the black probe is grounded.
•
Circuitry: This wire draws power from the A1 terminal on the key switch.
•
Interpretation: If there is not battery voltage at this terminal, the tractor is probably not function at all.
Look for a blown fuse or a bad key switch.
8.
Bottom right middle rounded-shape: The purple wire provides a ground signal to the RMC module when the
key switch is placed in the REVERSE CAUTION MODE.
•
Behavior: There should be continuity to ground at this terminal when the key switch is in the REVERSE
CAUTION MODE position.
•
Circuitry: When the key switch is in the REVERSE CAUTION MODE position, a ground path is estab-
lished by connecting terminal A2 to terminal L within the key switch. The purple wire from the RMC mod-
ule connects to A2, and a green ground wire connects to L.
•
Interpretation: If the purple wire fails to reach a ground path when the key switch is in the REVERSE
CAUTION MODE position, the RMC module will not arm or operate. Check the key switch for continuity
between A2 and L in the REVERSE CAUTION MODE position, confirm that the green wire connecting to
the L terminal does have good continuity to ground, and check for any loss of continuity in the purple wire
that extends from the key switch to the RMC module, including the molded connector between the two
components.
9.
If the RMC plug test indicates fault with any of the safety switches, the next step is to test the suspect switch.
The operation of those switches is described in the following sections.
