What kind of modules are you running? GM? Chinese? Do you have a good ground on the system. And what voltage are you seeing at the module itself. |

All good questions that I hadn’t thought about. I’ve run grounds all over the charging and ignition system so I don’t think that should be an issue. Mostly run the standard lx301 I guess Chinese modules. Not sure on the voltage so I’ll check that and get back to yall. |

I usually run a ground from the mounting screw of the module to the battery ground. Yes just verify your voltage at the module is not dropping off. |

Make sure the module is well heat-sunk, and make sure your line voltage with the engine running isn't spiky or too high. |

I know it’s not to high as it only runs about 13 to 13.5 volts after the relay upgrade. I usually use heatsink paste instead of the line they supply unless that might be my problem?

That should be fine. |

13 to 13.5 is a decent battery voltage number when warmed up. |
