The most common golf cart charger issue is a bad timer unit and faulty DC charger plug. If the timer unit gets faulty, the charger won’t cut off.
There are two types of timers: manual and automatic. The timer unit can be faulty because of a bad solid-state circuit board. And this is a serious case, undoubtedly.
On the contrary, a defective DC charger plug won’t allow your battery to get charged. Dust and other objects can get jammed onto the plug, preventing the proper connection.
You may notice the DC plug is excessively hot and get melted. Even a bad DC plug will be responsible for a fire hazard.
The charger wires or battery cables can be loose or damaged. At the same time, the cables and wires can be broken for various reasons.
Even the cables can melt in some serious cases. If the excessive current passes through the jumper cable, it can melt your golf cart charger cable. And overheating is the first step in this case.
Poor connection between the engine and chassis can also be responsible for melting your charger cable.
The fuse has a great role in protecting the charger components whenever the charger diodes fail. But, you may notice that the fuse of your charger gets damaged.
