The 36-Volt Analog State-Of-Charge Meter is a tool that no golf carter should go without. If your fuel gauge on your truck broke, you would be lost, or at least keeping track of your odometer to ensure you do not get stranded. We do not have that luxury on a golf cart. Even if you have an hour meter, that is a far cry from an accurate way to tell how much power had been consumed. These golf cart meters measure the range of voltage that the golf cart needs to run. A 36-volt golf cart has to have a minimum of 36-volts to run. At 35.9 volts, the solenoid is more than likely not going to click in, and the golf cart is not going anywhere.These voltage meters will allow you to see the overcharge on the batteries, telling you exactly how much juice you have left in your "tank." A 36-volt system will read almost 42-volts when it comes off the charger. Do not be fooled by terminology; call Buggies Unlimited today for golf cart parts and accessory solutions.
