Six 6V batteries make a 36V nominal pack when connected in series. Use five jumpers, each joining one battery's positive terminal to the next battery's negative terminal. Numbered along that path, the pack's main outputs are B1 negative and B6 positive. The cart's two main supply leads connect at those endpoints, separately from the five inter-battery jumpers.
Identify the batteries and the series path
Check the voltage label on each of the six batteries before selecting a wiring layout. Six batteries alone do not identify the system voltage: six 8V batteries in series form a 48V nominal pack, whereas six 6V batteries form 36V. Also check the cart's stated system voltage and its model-specific wiring diagram.
Label the batteries B1 through B6 in electrical order. B1 does not have to be the front-left battery, and the batteries do not need to sit in a straight row. What matters is which terminal each cable joins. Read the molded or printed plus and minus markings instead of inferring polarity from the direction a battery faces.
The series-connection principle is positive-to-next-negative, with the connected voltages added. Applied to this pack, the calculation is six times 6V, or 36V nominal.
Prepare before changing connections
Photograph and label the existing wiring, including charger and accessory leads. Switch off and secure the cart, disconnect charging equipment, and use the cart's service procedure for any Tow/Run setting and battery isolation. Battery-work precautions include disconnecting batteries and other power sources before electrical work. Turning off the key does not remove the voltage at battery terminals.
Use the specified cable sizes, terminal hardware, and tightening torque for the installed equipment. Keep tools and loose cable ends from bridging terminals. If the original wiring is damaged, unidentified, or already incorrect, establish the correct model-specific connections before dismantling it; a photograph alone is not proof that the old arrangement was right.
Connect the five jumpers and identify the outputs
With the cart and charger isolated as their instructions require, make the following inter-battery connections:
- Connect B1 positive to B2 negative.
- Connect B2 positive to B3 negative.
- Connect B3 positive to B4 negative.
- Connect B4 positive to B5 negative.
- Connect B5 positive to B6 negative.
B1 negative and B6 positive remain outside that jumper chain. These are the main negative and positive outputs respectively. They may already have vehicle cables attached in an assembled cart; “end terminal” does not mean a terminal with no wires on it.
Keep the vehicle supply isolated until the connection checks are complete. Do not add a sixth jumper between the pack endpoints, and do not connect opposite terminals of the same battery together. Charger and accessory leads belong at the locations specified in the vehicle diagram, not wherever an unused terminal is convenient.
Check the pack before returning the cart to service
Trace the five jumpers once more, terminal to terminal. Confirm that all six batteries participate in one series path and that the main supply leads are assigned to the correct endpoints. Inspect the cable routing, connections, and terminal covers before reconnecting the vehicle.
For the voltage check, use a suitably rated digital multimeter in DC-voltage mode, with black in COM and red in the voltage socket. Place black on B1 negative and red on B6 positive. Correct voltage-measurement setup matters: an A or mA socket must not be used to measure across the pack.
Expect a positive reading consistent with the battery manufacturer's guidance for the charge state and test conditions. “36V” is the pack's nominal rating, not an instruction to obtain exactly 36.0V. A negative or unexpected reading calls for checking the meter, terminal markings, and wiring before reconnecting the cart. Restore power only using the vehicle's specified procedure.
FAQs
Does the battery tray position determine which terminal is main positive?
No. Follow the series links and read the terminal markings. With the B1-to-B6 numbering used here, B6 positive is the main positive regardless of where B6 sits in the tray.
Are the main cart cables included in the five-jumper count?
No. Five jumpers connect the six batteries to each other; the main cart cables connect the completed pack to the vehicle at B1 negative and B6 positive.
Should a correctly wired 36V pack always measure exactly 36V?
No. Nominal voltage identifies the system, while the measured voltage depends on battery condition, charge state, and whether the pack is resting, charging, or supplying a load. Interpret the reading using the battery manufacturer's guidance.
