jimstim problem
Posted: Wed Jan 21, 2015 11:44 am
Build jimstim couple of years ago and used it without problem every now and again since then.
Last night I was using it testing COP's and somethings gone wrong. When I switch it on (whether or not its attached to megasquirt) it works for a couple of seconds and then U2 and F1 start to get very hot and it stops working. Have been over it as carefully as possible and don't see any sign of anything shorting any of the pins. Any ideas. Don't know where to start testing
