MS2 Works on stim, stops when DB9 plugs in

Post by beast02 »

After driving just fine for about a year, at a stop light I went to go when the light turned green and the car sputtered and died on me. I was barely able to fire it back up and get pulled over out of the way.

After some testing of the board and relay board, it seems I am getting all the 12V as I should on each.

I put the MSII on the stim and it works, lights flashing as it should.....and then the weird thing is, if I go to plug the DB9 into the plug on the MS2....the stim lights shut off like it totally shorted it all out. I'm a bit stumped on this one.

V3.0 board.

Strange.............. The first thing I would do is, try a different serial cable.
