Par Caddy Z1-Z2 – Troubleshooting Guide
Even though your Z1-Z2 is a very rugged and reliable machine, it is still a
machine with many moving parts, and may break down from time to time. We
need to know the symptoms of the problem in order to make a proper diagnosis.
f your Par Caddy breaks down, please run through the following troubleshooting
guide before emailing or calling us. The guide should reveal the real problem so
we can send you the right parts to get you back up and running. Don’t assume
anything.
A good way to bench test your Par Caddy is to set it on a workmate, milk carton
or box so that the drive wheels are not touching the ground or the bench.
Connect the battery and test all the items described below using both manual
and remote control modes.
Check for power
s the green light on in the handle control (lightning bolt window)?
1. f you have no power
a. s your battery dead or weak – make sure battery is good – don’t
assume – have it tested for both voltage and amp hour capacity if
possible. Also have your charger tested for output voltage – should
be about 28-29V for a nominal 24V battery.
b.
Make sure the connection from the power cord to the charger is
fully seated and tight. f this connection is loose your battery will not
charge.
c. Voltage reading ____________ - should be at least 25V after
charging.
d. Check the battery wiring harness – make sure it is tight on the
battery terminals.
e. Check the connector on the wiring harness – is it damaged in any
way? Are the little metal sleeves all visible in the connector holes?
f. Check the connection on the cart where the battery plugs in – is it
damaged in any way? Are one or more prongs blackened?
g. Microswitch under the red on/off button may be worn out preventing
the cart from powering on. Replace the handle electric board and
also the speed control POT as this could also be the cause.

h. f 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. f 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. s the hub securely fastened to the axle? s 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. f 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.
lectrical 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. t 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.

Manual Mode:
Speed control knob – is it operational starting from full off position.
Red start / stop button – does the cart stop when this button is firmly pressed.
Does the cart resume at the same speed when the button is pressed again.
Red button serves as both on-off and start-stop button. Press and hold for on-off.
Press and release right away for start-stop in manual mode. The other button
(green) is 10-20-30 yards timer (exactly same function as bottom timer button on
the remote handset.
Remote Mode:
Fwd button – turns both wheels fwd – each press increases speed one increment
Rev button – each press decreases speed one increment
Rev button from stop turns both wheels backwards
Right button from stop: Turns left wheel fwd
Right button while moving fwd: Stops right wheel and accelerates left one
Left button from stop: Turns right wheel fwd
Left button while moving fwd: Stops left wheel and accelerates right one
When you press any key on the remote does the red LED light up?
f the red light LED is dim – replace the batteries in the remote.
