MSD Bad Box
|
Wondering if anyone has had a MSD box go bad. I have a MSD 10 plus. New motor this year. We have had the motor running ran great but hard getting it started . We had a misfire while starting blamed it on a new cap I put on we changed caps again came back put old one back on still misfire. When they go do they go dead , or can they be intermittent. Just head scratching till everyone opens tomorrow. |

We were fighting problems and thought it might be ignition. However, MSD will swear up and down that the box can not cause a misfire. It either fires or it doesn't.
Later we found our problem and wasn't ignition. Just my experience |

What ended up being the problem llss puller? We changed cams and have a high duration now. Scratching our heads for sure. |

We just had a faulty autometer tach cause problems with my msd-10. It was acting like a rev limiter |

Robert, try putting a new power wire on going to the box. I had that same problem this year and it ended up being the power wire. |

Check your grounds as well. Have a friend that fought ignition problems for a while and it turned out to be a bad ground on the box. |
