Troubleshooting Guide: Error Code 34

Relevant Product: All vehicles with model # ending in "CA"

EV's Produced After: April 29, 2011

Other Indicators: Battery/Charging Issues and/or Reduced Run Times

Corrective Actions


Check Battery's Charge: Vehicles batteries could be crucially low. Charge batteries 6-8 hours depending on the state of discharge.


Check For Shorted Battery: Use a multimeter to check EACH individual batttery. Make sure each battery has the correct voltage. If the vehicle has standard 6 volt golf cart batteries, the reading should be around 6.25 volts. Having even ONE shorted battery can result in run times being reduced and causing Code 34 to appear.


Shorted Battery Cell: When measuring your volts with the multimeter, if your reading is 2 volts less, you have a shorted cell and the battery will need to be replaced. For example, a 6 volt battery with a 4 volt reading is the sign of a bad cell. Having a shorted cell can cause Code #34 to appear on your vehicle.


Examine Battery Terminals: Battery terminals that are loose or corroded can trigger Code #34. Check all connections to the battery's solenoid, motor and controller for corrosion and tightness. If obvious signs of corrosion, you can use a warm water & baking soda mixture to clean the terminals using a wire brush.


Water Level in Batteries: Checking your batteries' water level can help determine if they are being charged to full operating voltage. If the water level is low, the battery will need DISTILLED WATER added to approx. 3/8" from the bottom of the hole. Be careful not to overfill as this can result in the battery overflowing while being charged.


Confirm Vehicle is Charging/Check Screen Display for Fault Indicator: Once the vehicle has been plugged in to charge, confirm it is properly charging. If the vehicle is not charging, you will need to check the following possible issues (1) check the 120 Volt outlet for power (2) confirm power cord is plugged into the charger (3) check the condition of the power cord to make sure it is not damaged and in need of being replaced (4) if an extension cord is being used to charge your vehicle, it could be defective or too long for the charger to communicate properly (5) confirm there is power coming from the wall outlet.


Faulty Line Contactor (Power Solenoid): To check for a defective line contactor, use a multimeter to determine that the contactor is communicating with the battery. You can also do a continuity test to check for an open coil and confirm there is no breaks in the wires causing a miscommunication to the battery from the electrical wiring.


To prevent risk of electric shock, observe the following cautions:

Connect charger power cord to an outlet that has been properly installed and grounded in accordance with all local codes and ordinances. A grounded outlet is required to reduce risk of electric shock. Do not use ground adapters or modify the plug.

Do not touch uninsulated portion of output connector or uninsulated battery terminals. Disconnect the AC supply before making or breaking the connections to the battery.

Do not open or disassemble charger. Do not operate this charger if the AC supply cord is damaged or if the charger has received a sharp blow, been dropped, or otherwise damaged in any way. Refer all repair work to the manufacturer or qualified personnel.

This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.


Charger enclosure may be hot during charging. Use hand protection if handling the charger while charging.


No attempt should be made to open, repair, or otherwise modify the controller. Doing so may damage the controller and will void the warranty.
