Golf cart sat while you were away and will not start: what is recoverable

This is the October and November call in The Villages. A cart that worked fine in April sat in a hot garage while its owners spent the summer north, and now it is dead: no lights, no click, a charger that will not start. Some of those packs come back. Some do not, and the difference was decided in May by how the cart was left.

Check this first (fifteen minutes)

1. Measure pack voltage at the batteries. A 36V pack should sit near 38 volts, a 48V near 50 to 51. That number decides the next step.
2. Look at the water level on flooded batteries before charging anything. Plates that have been exposed are already damaged, and charging a dry cell makes it worse. Top up to just over the plates, charge, then fill properly afterward.
3. Check for corrosion and swelling. A swollen case or a leaking battery is finished. Heavy crust on terminals may be stopping the charge on its own.
4. Try the charger and watch it. Nothing at all usually means it cannot see enough voltage. A cycle that starts and quits after a few minutes means it looked and gave up.
5. Check the tow/run switch. A cart left in TOW will not drive even with a perfect pack.

What is usually going on

Every figure comes from the pricing page, and the $50–$100 service call is applied toward whatever the repair turns out to be.

Why a Florida summer is hard on a parked cart

Three mechanisms compound. Self-discharge roughly doubles for every 18 degrees of temperature rise, so a battery that would hold its charge for months in a mild garage loses it in weeks in a Central Florida garage in July. Electrolyte evaporates faster in heat, so a pack that was not watered before the trip can expose plates while nobody is there to notice. And sulphation builds faster when hot, so a pack sitting at half charge is not idle, it is actively degrading.

Add the parasitic loads that never truly switch off on some carts, and a pack left unattended through a Florida summer has very little chance without a plan.

The plan that prevents it

In order of effectiveness:

1. Leave it on a maintaining charger. Modern chargers are designed to be left connected, and this is the whole answer for most snowbird owners.
2. If the garage has no power, charge fully, water properly, and disconnect, then have a neighbour or a service check it monthly.
3. Water before you leave, not after you return. Watering a pack that has already run dry is repair, not maintenance.
4. A lithium cart is different. Store at a partial state of charge and use the main disconnect if the cart has one. Do not apply lead-acid habits to lithium or the reverse.

This is genuinely the difference between a cart that starts in November and a $1,500 invoice.

When the pack is finished

You will get numbers, not adjectives: individual load test results for each battery, so you can see which are gone and which are borderline. If the pack is finished, both options are priced honestly, lead-acid at $1,200–$1,800 or lithium at $1,600–$3,500, with an opinion about which suits this cart.

For owners who leave every summer, lithium has a specific advantage worth knowing: it self-discharges far more slowly and there is nothing to water, which removes this entire failure mode. On a cart that is itself old or low-value, the honest answer is still sometimes the budget pack, and we will say so. The battery cost calculator prices both.

If it is a gas cart and a new starter battery made things worse, with no lights, no horn and no crank at all, that is a connection problem rather than a dead battery; see gas cart has no power after a new battery.

A gas cart that cranks but acts starved for fuel

On a gas cart that sat, “it starts but won’t get any gas” usually means fuel is not reaching the engine fast enough, not that the engine itself has failed. The likely causes, roughly from cheapest to check:

1. Stale fuel. E-Z-GO’s owner’s manual says storing a vehicle for 30 days or more needs preparation “to prevent a build-up of varnish and gum in the fuel system,” and its storage steps add fuel stabilizer to the tank. A cart parked for a Florida summer without stabilizer is the classic case, and on a carbureted engine that varnish lands in the small passages of the carburetor.
2. A clogged inline fuel filter. Gas carts carry filters in the fuel line, and Club Car’s gasoline service manual gives fuel filters their own service section. A filter full of debris or varnish lets the engine fire and then starve under load.
3. The fuel pump. Many older carbureted carts use a pump driven by engine pulses through a short hose from the crankcase, so a cracked or loose pulse hose can starve the engine even when the pump is fine. Newer fuel-injected engines, such as E-Z-GO’s EX1 EFI, use an electrically powered pump with a relay instead.
4. A blocked tank vent. The tank has to breathe as fuel leaves it. Club Car’s service manual covers the fuel tank vent as a separate item, and a blocked vent can pull a vacuum that slows fuel flow.
5. Throttle and governor linkage. E-Z-GO’s maintenance chart lists the throttle/governor linkage and “governed speed” as a regular check. A binding linkage can feel exactly like fuel starvation. The manual also warns that tampering with the governor voids the warranty.

Fresh fuel and a new filter are the inexpensive first steps; a carburetor clean or pump comes after those are ruled out.

Book the return check before you fly back

The last two weeks of October and the first weeks of November are the busiest stretch of the year for exactly this reason: everyone comes back at once and everyone finds out at once. Booking a check for the week you return, rather than calling after you find the cart dead, is the difference between a same-week appointment and a wait.
