Golf Cart Maintenance, Batteries & Repair

A golf cart is the rare piece of equipment people use almost every day and service almost never. There is no oil light, no hour meter most owners look at, and on an electric cart nothing that makes noise when something is wrong — so the first symptom is usually the cart simply not going. Nearly all of it traces back to a handful of things, and most of those are cheaper to keep up with than to fix after the fact.

1. Electric or Gas Changes What the Cart Needs

The two halves of the golf cart world barely overlap on maintenance. An electric cart is a battery pack, a controller, a solenoid and a motor, and almost everything that goes wrong with it is electrical. A gas cart is a small engine with a clutch and belt drive, and it fails for the same reasons any other small engine does — stale fuel, a gummed carburetor, a neglected air filter.

Knowing which one you have decides where to look first. An electric cart that will not move is a charging or connection problem until proven otherwise. A gas cart that will not start is a fuel problem until proven otherwise, and the fixes have nothing in common.

2. Battery Care Is the Whole Ballgame on an Electric Cart

Most electric carts around here still run a flooded lead-acid pack, and those batteries need water. The plates have to stay covered, and topping off with distilled water after charging — never before, and never with tap water — is the single habit that separates a pack that lasts from one that does not. Check every cell, not just the easy ones at the front.

• Corroded terminals are the most common cause of a cart that runs weak or cuts out under load.
• Loose cable connections generate heat, and heat at a terminal is a warning sign worth acting on immediately.
• Low water exposes the plates and does damage that no amount of later charging undoes.
• Deep discharges — running a pack down hard and leaving it sitting — shorten its life faster than mileage ever will.

3. When the Problem Is Actually the Charger

A cart that will not charge is not automatically a cart that needs batteries, and that is an expensive assumption to get wrong. Work outward from the wall: the outlet, the cord, the charger itself, the receptacle on the cart, and the main pack cables. A charger that clicks and quits, or never starts at all, often has nothing wrong with the batteries behind it.

Many chargers will also refuse to start on a pack that has fallen below a minimum voltage, which reads exactly like a dead charger from the outside. That distinction — a charger that failed versus a pack too low to wake it up — is worth pinning down with a meter before anyone spends money.

4. Gas Carts: Fuel, Oil, Belts and the Clutch

A gas cart that sat through a season with fuel in the tank is the same story as any other small engine: ethanol-blended gas breaks down, leaves varnish in the carburetor passages, and the cart cranks without firing. Our notes on ethanol gas and small engines cover what is happening in that tank and why it happens so fast.

Beyond fuel, a gas cart wants its oil changed on schedule, its air filter serviced, and its drive belt and clutches inspected. A glazed or cracked belt slips on a hill with a load aboard, and clutches that are dirty or worn make a cart feel gutless in a way people often blame on the engine.

5. Tires, Brakes and Steering

Cart tires run low pressure, and they lose it quietly. Underinflated tires make an electric cart work harder and drain the pack faster, and they wear unevenly enough that you will notice it in the steering before you notice it in the tread. Check them cold, and check all four rather than the one that looks flat.

Brakes are the item most worth staying ahead of, especially on a cart that carries people down a farm lane or a neighborhood hill. Mechanical drum brakes and their cables go out of adjustment gradually, so the pedal travel grows a little at a time and nobody notices until it is bad. Steering and suspension grease points are on the same list — a few minutes with a grease gun each season prevents most of the front-end slop that shows up later.

6. Off-Season and Winter Storage

Cold weather is hard on a lead-acid pack, and a cart parked for the winter is where a lot of batteries quietly die. The pack should go into storage charged rather than run down, and stay that way — check what your charger and batteries specify for long-term storage rather than guessing, since setups differ. Clean the tops of the batteries while you are at it; dirt and moisture across a battery top will slowly drain it on their own.

Gas carts follow the same off-season rules as the rest of the shed: stabilize the fuel or run the tank dry, service the filter, and store it dry. Our guide to winterizing your equipment walks through why that matters.

When to Call the Shop

Watering batteries, cleaning terminals, checking tire pressure and keeping a gas cart's oil and filter current are all reasonable driveway jobs, and staying on top of them is most of what keeps a cart out of a shop in the first place. Where it stops being driveway work is anything that needs a meter and a known-good reference to interpret: a solenoid that clicks but does not pass current, a controller fault, a pack with one bad battery quietly dragging the other five down, or brakes that need more than a cable adjustment.

Golf Cart FAQ

How long should a set of golf cart batteries last?
It depends far more on charging and watering habits than on age alone. A flooded lead-acid pack that is topped off with distilled water and charged fully after each use will outlast one that is run down hard and left sitting.

Why won't my electric cart move even though the batteries are charged?
Check the simple things first: the run/tow switch, the key switch and the main cable connections at the battery pack. Beyond those, a failing solenoid or controller is the usual culprit, and that is a shop diagnosis rather than a driveway one.

Do I need to charge my cart over the winter?
A lead-acid pack should not be left sitting discharged through cold weather. Keep it charged rather than letting it drain down, and follow what your charger and battery manufacturer specify for long-term storage on your setup.
