It goes into the wiring harness as you said. it has no breaks and is in good shape. --- In DMCForum@xxxxxxxxxxxxxxx, "Walter Coe" <Whalt@xxxx> wrote: > > module switches the ground wire on and off many times per > second. > > No. Rich, the following is what I think, but I'm sometimes > wrong: > > The frequency valve ground is unswitched, and the positive > lead is the one that is switched/pulsed.
