I have a small B-7100 that won't start. I got a new battery for it and used it then a week later went to turn the switch and the glow plugs showed they were working but when I tried to start it, nothing. It did kind of sound like a switch maybe went out but after that, nothing. I won't even turn over. It's like there is no electric getting to the starter. is there a switch on the dash that could have maybe gotten shorted out?
