Gas powered 95 Marathon just died. Battery replaced and nothing. Can hook booster cables from my truck to the battery, press the gas and it’ll go. Cables come off, nothing.
Chad Smith just to clarify. you replaced the battery with a new one, that does not work. You put the booster cables on the battery clamps of your cart and it runs? your cart is an Ez-Go Marathon? Right now it does sound like a bad starter/generator assembly
Start off by checking the wiring and make sure they are tight and no corrosion on the connectors etc. Check the voltage regulator as well. Even so it’s a bit newer the principal is still the same on here
