Test Procedure 11 - On-board Computer Lockout Circuit:
1. Inspect the charger receptacle for water in the contacts. If water is found, proceed as follows:
NOTE
• IF THE BATTERY PACK IS WET, MAKE SURE THAT THE NO. 10 GREY WIRE FROM THE RECEP-
TACLE IS NOT TOUCHING ANY OF THE BATTERIES. TIE WRAP NO. 10 GREY LEAD AND NO.
18 GREY WIRE TO THE WIRE HARNESS CONDUIT IF NECESSARY.
1.1. Disconnect the batteries as shown (Figure 17-1, Page 17-2).
1.2. Discharge the controller (See instructions in the WARNING on page 17-1).
1.2. Remove the receptacle from the vehicle (See Page 19-22).
1.3. Dry the receptacle by wiping it with a clean dry cloth and by blowing into the contacts with com-
pressed air.
1.4. Inspect the black butyl material that seals the entrance of the grey sense lead into the charger
receptacle (See Figure 19-6, Page 19-14). If lead is not sealed, remove butyl material and seal with
new butyl material.
1.5. Re-install the charger receptacle into the vehicle.
2. It is possible that the On-board Computer can become "locked up", causing the OBC solenoid lockout
circuit to malfunction. If this condition is suspected, "reboot" the computer as follows:
2.1. Make sure that the batteries are disconnected as shown (Figure 17-1, Page 17-2) and that the con-
troller has been discharged (See instructions in the WARNING on page 17-1).
2.2. Reconnect the batteries.
2.3. To determine if the computer was "locked up" and that it is now functioning properly, attempt to drive
the vehicle. If the problem has been corrected, the vehicle will function normally.
3. If it is determined that computer "lockup" is not the problem, it will be necessary to by-pass the OBC
solenoid lockout circuit in order to isolate the problem. Follow the procedures below:
3.1. Make sure that the batteries are disconnected as shown (Figure 17-1, Page 17-2) and that the con-
troller has been discharged (See instructions in the WARNING on page 17-1).
3.2. Connect one end of a jumper wire to the small (coil) post of the solenoid (with No. 18 yellow wire
attached). Connect the other end of the jumper wire to the negative post of battery No. 6.
3.3. Reconnect the batteries.
3.4. If the vehicle can be driven with the jumper wire attached, then the on-board computer has failed
and must be replaced. If the vehicle cannot be driven with the jumper wire attached, then study the
Troubleshooting Guide on pages 17-6 through 17-9 to find and check the other circuits that could
cause the same symptoms.
Test Procedure 12 - Half-speed Reverse Limit Switch (F&R Limit Switch No. 3):
1. Check for proper wiring (Figure 17-6 or 17-8, Page 17-11 or 17-14) and tight connections.
2. Using a continuity tester or VOM set to ohms, check continuity across common (COM) and normally
open (NO); and across common (COM) and normally closed (NC) (See Figure 17-10).
With the limit switch lever up (not depressed), readings should be:
COM to NC: Zero (or continuity tester is illuminated)
COM to NO: Infinity (or continuity tester is not illuminated)
