I know this has been asked before, but I need some advice. I have my master disconnect switch wired to the ground side instead of the pos. side. It works but won't pass tech because engine keeps running after master switch is turned off because alternator keeps it running. I don't want to fabricate new battery cables or run alt. wire back to trunk. I'm thinking of installing another cutoff type switch in the car that just breaks the circuit in the alt. output wire. (one-wire alt.). This way I can shut the alt. off in tech and leave it off for a ten second pass and the engine should then shut off when master is turned off, correct? Thanks for any help, I appreciate it, Lee
