SECTION 1 - NO POWER

Symptoms:
! The batteries are fully charged.
! All electrical components are connected correctly.
! The on/off key is pressed and the power does not come on.
Diagnosis:
The power has been interrupted somewhere in the system.
Solution:
Use the following procedure to find the source of the interruption:
1. Locate the off-board charging socket (1a) on the front of
the VSI controller (1). See diagram 1.
2. Measure voltage across pin 1 (B+) and pin 2 (B-) on con-
nector 1a. See figure 2.
— If your multimeter indicates about 25VDC, then replace the
VSI controller (1) and retest the system.
— If your multimeter indicates 0VDC, then go to the next step.
— If your multimeter indicates 18VDC or less (but not 0VDC),
then recharge the batteries and retest the system.
3. Remove the battery box from the Go-Chair. Refer to the
Go-Chair owner's manual.
4. Measure voltage across the negative and positive battery
contact pads (5e and 6d) on the underside of the battery
box. See diagram 2.
— If your multimeter indicates more than 18VDC, then go to
step 9.
— If your multimeter indicates 18VDC or less (but not 0VDC),
then recharge the batteries and retest the system.
— If your multimeter indicates 0VDC, then go to the next step.
5. Remove the hardware from the bottom of the battery box
and open the battery box. See figure 3.
6. Measure voltage across the two outermost battery termi-
nals. See figure 4.
— If your multimeter indicates more than 0VDC, then replace
the battery contact pads (5d, 5e, and 6d) and retest the system.
— If your multimeter indicates 0VDC, then go to the next step.
