EZGO starter generator replacement guide. An EZGO gas cart that will not crank or charge usually needs a starter generator. The unit has two jobs. It cranks the engine at startup, and it charges the battery once the engine is running. That is why one failed unit can create two problems at once. Common signs include no crank, whining sound on startup, intermittent engagement, battery drain, and dim lights. Before ordering, confirm the cart model, year, engine type, and pulley setup. Marathon, TXT, and RXV models do not always share the same fitment. During installation, check the belt condition and do not forget the jumper wire between terminals. A misplaced jumper can cause no start or no charge.
