If there were one part out there that can cause myriad different issues, ignition coils would be that part. Your golf cart might be running but not too well; it could repeatedly be backfiring or losing all its power on inclines. All of these symptoms point toward your E-Z-GO 4-cycle Ignition Coil. Please do yourself a favor, pick one of them up today, and get your cart back to 100-percent.When your E-Z-GO 4-cycle Ignition Coil is working correctly, it will produce a brilliant white or blue spark. This flame should continually spark as long as the pedal is depressed. If the color is red, yellow, or orange, the spark is not hot enough to ignite the cylinder's fuel. If this is the case, give Buggies Unlimited a call and get an aftermarket coil today. The same goes for the consistency of the spark. If it comes and goes and does not continually spark as you hold the pedal down, time for a new aftermarket coil.
