Hot Rods Welding with an MSD Box

In that case which one would squeal louder, the owner of the tit or the washer as the belt slipped ?

 

When did MSD make washing machines? And for the O.P> just disconnect the ground from the box as well.....

 

I’m here to tell you that there’s no way you’re going to be able to weld with the MSD box if you follow this advice, everyone knows that when you weld you definitely need a ground.
