WHY IS MY CART SHUDDERING?
Question: My cart is starting to ‘shudder’ when I hit the accelerator pedal instead of going forward. If I let up on the pedal it will slowly proceed forward but if I press the pedal to increase speed it will start ‘shuddering’ again and almost come to a complete stop. The reverse seems just fine. The problem is only when I try to go forward. The problem is exasperated if I attempt to go uphill.
Answer: The “shuddering in forward but seems to run fine in reverse” is a very common issue with the 36-volt resistor coil for Club Cars. The reason for this is this system uses all the batteries for forward and only four for reverse.
How to find the cause of the problem:
First, you will need to check for any loose or bad battery cable connections.
Second, conduct a load test on the batteries one at a time. This will determine if a bad battery is an issue.
To perform this test:
Jack up the rear of the cart and turn the key switch on. With the car in the forward gear, depress the accelerator so the tires and wheels are spinning greater than half speed.
Then, slightly depress the brake. This places the battery pack under a load.
With a voltmeter, check each battery in sequence while the tires are spinning and the brake is depressed. The batteries should not drop below their indicated voltage.
