Frequently Asked Questions
Taylor-Dunn Technical Information

I have brand new batteries, but they don't last very long on one charge. Why?
New batteries require a break-in period of up to 40 cycles. The batteries will not have their full capacity during this time and may require longer charging times. It is not unusual for charge times to exceed 15 hours with new batteries.
My charger is beeping. What does this indicate?
The Signet chargers, model HB and HBS (600-24, 1000-36 and 1000-48), will emit an audible beeping sound when there is a fault present. The HB model faults are indicated by the flashing of all three charge status lights (50%, 75%, and 100% lights). The HBS model has its own fault indicator light (labeled "FAULT"). NOTE: A flashing fault is NOT necessarily an indication of a failed charger. Refer to your vehicle's service manual for a list of fault descriptions. To obtain a manual, use our dealer locator to contact your nearest Authorized Taylor-Dunn Dealer.
What is Sevcon fault Fxxxxx?
Fault codes with the format Fxxxxx (example: F01004) are displayed on the Smart View Display gauge installed on most Sevcon controlled Taylor-Dunn vehicles. For a complete list of faults and description and tips on troubleshooting, refer to your vehicle’s service manual. To obtain a manual, use our dealer locator to contact your nearest Authorized Taylor-Dunn Dealer.

Taylor-Dunn cannot be held responsible for damages or injuries resulting from installing non-OEM components in any vehicle. Taylor-Dunn is a vehicle manufacturer and does not manufacture parts or assemblies for use in other vehicles. The information provided is to be used for reference only. Taylor-Dunn cannot provide any further information regarding adapting any component or assembly to your installation.

My cart does not run.
There are many causes for a no travel issue on an electric powered vehicle. Troubleshooting the electrical system is mandatory to determine the cause. DO NOT replace components as a troubleshooting method. Confirm that all batteries are in good condition by performing a load test and specific gravity test. Check battery cable connections. Perform ALL required troubleshooting tests to identify the fault. A detailed troubleshooting guide is included in your vehicle's service manual. All tests in the manual assume the vehicle is wired correctly. Refer to the wiring schematic to confirm this before testing components.
My cart only runs in forward (or) my cart only runs in reverse.
Depending on the control system, there are a few possible causes for this symptom. Below are examples of our most common control systems. Refer to your vehicle service manual for more information.
There are three components that, if faulty, would result in this symptom:
- The Forward & Reverse (F&R) switch
- The wiring from F&R switch to the F&R solenoids
- The forward or reverse solenoid
- The F&R switch
- The wiring from F&R switch
- The directional transistors internal to the Sevcon controller
- A faulty forward solenoid could result in no reverse or vise versa.
- There are tests available to check the transistors. See service manual for details.
I'm not sure what part I need. Can you help me find the right one?
Any parts questions should be directed to your local parts and service dealer. Use our dealer locator to contact your nearest Authorized Taylor-Dunn Dealer.
How do I get vehicle dimensions and specifications?

When my vehicle goes up an incline it stops, or "cuts out" during operation. What is wrong?
All Taylor-Dunn vehicles have a maximum grade rating. Grade is the pitch of a slope such as a hill, road, or sidewalk. Check your vehicle's specs to confirm the grade you are travelling on does not exceed the maximum grade rating. This would be considered overloading the vehicle and could result in this symptom. Vehicle specifications can be found on our site on the "vehicles" page. If the grade is within the specs range, confirm the batteries are in good condition by performing a load test and specific gravity test.
