Troubleshooting
Problem: Why won’t my
trike turn on?
This is the most common problem we encounter and the solution is typically very simple.
Solution:
1.
Check that the battery is fully charged. Use a voltmeter and test the output on the charging
terminals if you do not have an ebike computer. The voltage should be within 10% of your
nominal voltage. For instance, if you have a 52v battery, you should get ~52v /- 5v.
a.
If you are having trouble charging the battery, please look below about charging your
battery.
2.
Make sure the main connector from the battery output lead is plugged in and secure.
3.
There is a problem with the controller. Open the Battery Case and check to see if controller light
is red on actual controller.
a.
If no light is on, you most likely have a bad controller. Most typical problem is the on/off
switch going bad. Send in controller for testing.
b.
If there is a light, please look at your E-bike computer to see what it is indicating. If the
computer says “Pass” and the bike does not work, check the connectors.
Remove the
battery, from the case and make sure the throttle 4 pin connector, the 3 plug phase
wires (motor to controller connection), and the hall sensor plug (geared motors only)
are securely connected. Unplug and re-plug in each connector. Once you do this and if
all connectors are intact, you have a bad controller. Please contact Standard Bearer
Machines, LLC to return it for testing.
Problem: I drove my Trike until it went completely dead and now it will not charge.
This is a problem that occurs when you fully deplete the battery. The BMS on the battery protects the
battery from discharging any further and force shuts itself off. First step would be to open the battery
case, remove and unplug the battery from the controller and try to charge. If that does not work, to
“wake up” the battery, you must “jump” the BMS.
Solution:
Jump your battery by opening removing it from the battery case (4 screws) and disconnecting the
battery from the controller and then reconnecting the battery. In most cases, this action is sufficient to
“wake up” the battery so it will charge again. IF this action fails to work contact Standard Bearer
Machines, to order a special jump cable.
Problem: I cannot get my battery to charge or my charger is not working
Many users do not realize the importance of properly charging your battery. Please look at the section in
the manual about charging your battery. Most common solution is blown fuse in the charger
Solution:
You have a fuse(s) blown in the charger. All chargers have 2 fuses, one located in the front screw cap
and the other located in the rear where the power plug wire goes into. Unplug the charger from the
power source and the batter case to replace the fuses.
Problem: The trike feels sluggish on hills
If you are not pedaling along with the motor at any power setting, you are relying completely on the
motor only to get you up the hill. NEVER fully rely on the motor for power when climbing, riding in sand,
