Got a 1997 Ram 2500 with 5.9 gas motor. truck starts and runs fine without Autometer Sport Comp tach hooked up. Hook tach up to signal wire on coil, truck wont start. unhook wire to coil, truck fires right up. Any suggestions what this might be?

Thanks for the help!

The tach should be on the neg side of coil. If it is maybe tach shorted out.

with the tach hooked up and motor not starting,, crank the starter and watch the tach,,,if you can see the light bulb in the tach plusating when its cranking there is a short in the tach and it will not start,,, ive had an auto meter and a stewart warner tach both do the same thing resulting in a no start,,just my experience,,good luck,,, call auto meter ask if that is a warranty issue
