When you have issues with a golf cart charger, it can make your stomach drop. The first thing that comes to almost everyone's mind is the last time they had to buy one and the price that got dropped on them. Let's not jump to conclusions so fast; it may be a more minor, cheaper charger component that we can easily replace, like the 40amp Fuse For Lester Chargers. Fuses are relatively manageable to test.Generally, fuses have a small length of wire inside that gets connected to a specific point on the fuse. Most of the time, there is a clear center section of the golf car fuse, or there is a window that allows you to view the thin metal strip within. If the metal band is severed, the fuse is no good and will cause a no charge scenario. Most voltmeters have a fust testing option, or you can read it for continuity. Either way, if it's wrong, call Buggies Unlimited and get it replaced at an affordable!
