Help!! Golf cart goes by itself!

[disny4fun]

This forum is beyond helpful! I've found answers to almost all my golf cart problems. However, I have another one! Found out yesterday a coil was broken, but this never stopped the golf cart from running. We were having arcing problems at the contacts on the wiper board even though the brush assembly was replaced. Contacts are smooth and in good condition. Once the brush assembly was replaced, the arcing was worse. This is why we checked the coils then found one broken. Repaired the broken coil and now the golf cart moves in forward and reverse when the key is turned on without pressing the accelerator. The brush assembly remains on the first contact (dead one) on the wiper board even with the golf cart moving. Once the accelerator is pressed, it moves up the wiper board. HELP! Have checked all the wiring and everything seems fine. Any other suggestions?
