Why Does My Golf Cart Go Slow Up Hills. A low ampacity controller small or faulty cables or weak batteries can slow down the golf cart. Air fuel mixture screw should be set at 15 turns open from full shut.
2 Check the level of the battery electrolyte periodically fill with distilled water to about 14 below the vent ring. Your batteries may have the proper voltage and may not hold a charge under load. You can take a look at the speed sensor and figure out if any of the wirings have come loose.
The pack voltage of the batteries installed on your Yamaha golf cart can be checked by connecting a voltmeter to.
EZ-GO Cart 4M99 Loses power when driving see my description. When the cart becomes hot the voltage also drops. So not real easy to take it back. Can be programmed to stay slow up AND down the hills so you dont wear out brakes.
