| Post subject: | MSD troubles |
My msd box is breaking down after engine runs for a while.Sometimes it runs an hour and sometimes it runs for 5 min.I put a new 6al on it and it does the same thing.Swithed coils and it does the same thing.The only thing i haven't changed is the msd distr. I think it could be that or i have a bad ground on buggy somewhere.Seems like i have a few volts going threw my chassy and kicking in some kind of protection on the 6al.If i unhook the box from the b+ for a few min then it will start back up.Any Input? |

When it stops.. How do you know it is the MSD? Do you loose spark? What if you just let it sit for a few minutes without disconnecting the B+? Will is still start up or does it only start after disconnecting the B+? |

Yea it looses all ignition spark.If you unhook b+ wire it seems to start back up after a few min.If you don't unhook the b+ wire then you have to leave buggy set for a few hours before it will restart.Just now trying to trouble shoot it.Hard to work on in woods without volt meter or test light.I unhooked the msd b+ wire and the ignition wire for a few min and when i touched them to the alt b+ wire to try and start buggy,the alt turned over a half of a rotation.Like the 6al was storing juice in it.Didn't make sence. |

Check your grounds.Also are the main power wires from the MSD box hooked directly to the battery? |
