When To Use This Document
Use this document when you need to trouble shoot a Power system using a J-Volt Kit.
- Unplug cart from wall outlet before continuing
- J-Volt Kit
- Phillips screwdriver
Process / Instructions
Please perform these steps only if your JACO battery system is not providing any power.
- Check for Battery Voltage:
- Ensure the JACO battery system is not plugged into the wall
- Take the J-Volt cable and install it onto the battery cable as shown in Fig. 2
- Turn the J-Volt meter from the OFF position to the 200 on the left marked with a red circle. Refer to Fig. 3
- Record the battery serial number, firmware revision, and voltage reading. Then label this reading as "Before Charging" on the paper.
- If the battery type is a J48 and the voltage is between 35 to 44 Volts, Recharge the power supply for at least 4 hours. NOTE: the inverter will only provide output power when the battery voltage measures over 44 Volts. With aged or weak batteries, the minimum voltage necessary to produce output may increase to as high as 49 volts.
- If the battery type is a J24 and the voltage is between 19 to 22 volts, recharge the power supply for at least 4 hours. Note: The inverter will only provide output power when the battery voltage measures over 24 Volts. with aged or weak battery, the minimum voltage necessary to produce output may increase to as high as 24.5 Volts.Note: The wire labeled "Battery" is sometimes hard to remove from the CartCare Adapter. If this is the case, press on the lock tab located on the center of the connector and wiggle it left and right to loosen.
- Check for Charger Voltage
- Plug the battery Ac line cord into the wall outlet or power strip that is plugged into the wall outlet. Referance to Fig. 4
- Record the voltage reading, and label this reading as "During Charging" on the paper.
- If the "During Charging" voltage is higher than Step 1 " Before Charging", then the charger is operating and functional.Outcome: If charger is good, continue to Step 3. If charger is bad, ensure the wall outlet does provide power. Step 3 assumes that the battery voltage is sufficient to provide power, and the charger is functional.
- Check power Output:
- Set the inverter switch to the ON position
- Plug device peripheral into the inverter outlet and test for power.
- Record "Power" or "No power" on paper.
If the device turns on, it would mean the inverter is functional.
If the device does not turn on, plug the Battery AC line cord into the wall outlet.
- If the device does turns on, the battery cells are weak and needs replacement.
- If the device does not turn on, the inverter has failed.

The information above will help JACO determine which component is at fault. When we receive the failed component, we will test it against the Paper Result that was provided to us and make any changes necessary to the troubleshooting procedures to ensure its full effectiveness.
By performing this troubleshooting, you have already decreased call, processing, and delivery time. This guide will help you determine defective component and purchase only necessary parts rather than a whole battery. This will save everyone time and money in the long run.
