If you have an old charger, the chances are that you have one of these Lester 25-Amp Dual-Link Fuses on the outside front or rear face. Newer chargers do not use them, but anything made by Lester before a specific year all had them. It is a small triangular item that could fit in the palm of your hand. Having one of these blow out on you is never a good thing. Most of the time, it will prevent the golf cart from charging altogether. Sometimes though, it will allow the charger to charge but not shut off when it's supposed to. This is a rare instance for this item to cause, but it can be far more expensive to fix if it ruins your batteries through overcharging.This will fit several Lester models, they are; 17910, 16500, 14100, 14390, 13165, 13110, 9800, 9700, 9695, 9611, 9032, 9028, 9027, 8946, 7850, 7710, 6730, 6720, and 6430. The Club Car 48-volt Powerdrive charger used this fuse. So did the Columbia, Harley Davidson, EZGO, and Yamaha 36-volt models. Buggies Unlimited is waiting to hear from you.
