Helping out a freind with a 2) 1050 polaris One with no spark and the other has really weak sprark. The one with weak spark has New battery I tested volts when cranking at the cdi box. Checked all groungs. Did the stater check (good) Un hooked the black and yellow wire at the cdi box. It does not have the 1050 update kit. Some put differant plug wire ends ( regular boots )on the spark plugs. Could that be a problem?
