SCENARIO 2: BATTERY PACK WILL NOT CHARGE
The battery charger needs to “see” at least 22VDC at the charger port. Otherwise, it may not send a charging
current to the batteries. This test will ensure that the battery voltage is making it to the charger port., and that the
battery pack is working properly.
If you are unsure of the correct way to measure voltage or resistance, refer to Appendix A and
B in this manual before proceeding.
Check Battery Charger Voltage.
1.
Open the tiller XLR port and check the voltage across pin 1 and pin 2.
See figure 18.
Refer to the wir ing diagr am on page 11.
• 24
-
29VDC (or battery voltage on pack?)
-
Go to the next step.
• More than 22VDC on pack?
-
Try to recharge the battery pack.
Load test and replace if necessary.
• 0VDC?
-
Replace the battery pack.
2.
Open the controller cover directly under the seat.
3.
Plug the charger into the XLR charger port and then into a wall outlet.
4.
Measure voltage across the B+ and B
-
connections on the controller (4).
See figure 19.
Refer to the wir ing diagr am on page 11.
Does the voltage increase?
• Yes?
-
Load test the batteries and replace as necessary.
• No?
-
But there is voltage. If the voltage is lower than 22VDC, then replace the batteries. If the voltage is 22VDC
or greater, then replace the charger.
