MSD 6M-2L BOX need ground ?
Let’s talk about the MSD 6M-2L box
Last night a want to start my engine on the stand .
i dont mounted my box on the braket so i put a old shirt on the bloc for not scratch the paint an drop the MSD box on it . Plug the black wire on the ground and the red on positive and 12V on the ignition .. the engine wont start … no fire . After a lot of test i took a wire directly on the corner of the box and go to the negative terminal on the batterie, engine start and run find . Y remove the wire and the engine shut off …
so if it’s normal that the box need to be mounted on as ground surface ? Or me box have a problem ?

Yess the black wire on the box is ground directly on the battery terminal . In the boat the box is mounted on the metal braket on the engine and run fine . But if the box does not mounted on the braket will not fire . I need to make the box housing ground to have fire .

when I run engines with MSD boxes on the test stand the box is usually just laying on the ground. if you are having to ground the case then I would say there is a broken ground circuit inside the box.

Its a fully podded box so you aren't getting into it like the red automotive boxes. MSD doesn't rebuild them either cause of this. If its new, I'd call them or where go it from and if used, dammit!
