TROUBLESHOOTING GUIDE

Vehicle does not run

Vehicle was running 

but suddenly stopped

Undercharged battery

Tripped thermal fuse 

Electrical switch damage

Dead battery

Motor damage

Loose wires or connectors

Charge the battery. A new battery should 

have been charged for at least 18 hours 

before using the vehicle for the first time. 

After first-time use, recharge the battery 

for at least 12 hours after each use. Never 

charge the battery longer than 30 hours.

Check all connectors. Make sure the battery 

connector is tightly plugged into the charger 

connector, and that the charger is plugged 

into the wall outlet.

Make sure that there is power flow to the 

wall outlet.

The built-in thermal fuse may “trip” and shut 

down operation of the vehicle if the vehicle 

is overloaded or the driving conditions 

too severe. Once a fuse has “tripped”, set 

the power switch to the “OFF” position, 

release the foot pedal, and wait 2 minutes 

before operating the vehicle again. To avoid 

repeated automatic shutdowns, do not 

overload the vehicle by exceeding the 130 

Ib maximum weight capacity or by towing 

anything behind the vehicle. Do not drive 

up hills or run into fixed objects, which can 

cause the wheels to stop spinning while 

power is still being supplied to the motors.

The electrical switches can become corroded 

due to exposure to water or moisture, or can 

jam due to loose dirt, sand or gravel.

Check all wires and connectors. Make sure 

the battery connector is tightly plugged into 

the control module connector and that there 

are no loose wires around the motor.

If your battery is old or if you have not 

followed Battery Care instructions, your 

battery may be dead. Replace only with an 

original 12 Volt (10 Amp/Hr.) battery with 

built-in thermal fuse. Do not use non-original 

substitute parts.

Visit the Dynacraft website and replace with 

a new motor.

Check all wires and connectors. Make sure 

the battery connector is tightly plugged into 

the control module connector, and that there 

are no loose wires around the motors.
