h. If only one motor runs then the problem is likely mechanical (see
next Section 2 - or there is a loose connection to one of the motor
leads. To check for loose connections, you must remove the 4
motor set hex bolts, pull the motors out breaking the silicone seal,
and disconnect and re-seat all the connectors to the ECU. Pinch
the female side with small pliers so that the male prong fits in
tighter. Before reassembly connect the battery and test.
2. If you have power, next we need to determine if the problem is mechanical
or electrical. What are the symptoms? Please tell us exactly what the
machine is doing – is it pulling to one side, won’t go forward, spins in place
etc. etc.
3. Check the wheels and drive hubs. Remove the wheels and inspect the
axle drive hubs. Is the hub securely fastened to the axle? Is the pin
holding it onto the axle intact? Are the wheel hubs fastened securely to the
wheel. Tighten all the hex head bolts to very snug, but do not overtighten.
Cart pulls left or right
– first check # 3 above. If wheels and drive system are
OK you can adjust front wheel alignment. Loosen the axle nuts (leave snug) and
adjust alignment by moving the right side of the axle slightly forward or back
using the adjusting mechanism on the right side of the wheel. Re-tighten nuts
and test. Repeat procedure if further adjustment is necessary.
Electrical Issues
1. There are only 3 electrical components in your Par Caddy Z besides the
main battery:
a. Control Panel – handle control, which powers the cart on and off,
and contains the manual controls.
b. Remote transmitter
c. ECU (electronic control unit) - the brains of the system. The ECU
receives the signals from the remote transmitter and translates
them into motor movements.
By describing the symptoms of the problem in as much detail as possible, we can
usually determine what is the offending component. It could be as simple as a
loose connector.
To assist us in determining your problem, please operate the unit with the drive
wheels raised off the ground. Test all functions in both manual and remote
modes and report drive wheel movements with each command.
