hey hows it going? im working on a 89 300 bayou. it has weak spark on the plug sometimes, very iratic. everything seems to be fine going into the coil. yellow and red wire has constant power and other wire seems to be blinking with the spin of the motor. my guess would be the coil but i need some opiniions before going and spending the $$$$$$$$$$$. thank you for your time! joe
