What will the consequences be if one or more of the mosfets connected to the 12 volt perm line short from drain to source?
Do you have the schematic for the flip flops?
You wouldn't be able to turn anything off,the starter won't spin unless you push the brake pedal down.But why would this happen randomly and be any more relevant because I'm using MOSFETs,the same could happen with sticking relay contacts surely? As long as I use the correct automotive MOSFETs surely there won't be any problems?
Flip flops are just standard 555 circuits,the top one with one button to set and another to reset and the bottom one has just one to set and reset.
