Hello, Has anyone of you had any problems with the petronix ignition system? The first two that I instaled in my 235 chevy engine lasted obout 2 months each and went bad. I just installed the third one and the motor will not fire let alone start. I connected a jumper wire from the positive post on the battery and the pos. post on the coil thereby bypassing the ignition circuit and still nothing. I prevously performed a detailed check of the ignition system and everything checked out normal. Are these problems inherent with these units or could something else be going on? Thanks for your help. olgzr
