Hi,
I made a simple powerswitch using a Pmosfet and a transistor,
basicly what it does is it takes away the power from 4injectors wich run my bike. In that way i can kill the engine for a short time and shiftup.
The problem i find is that it works well until i reach third!
if i upshift from 1 to seconds it goes well but when i enter third everything dies.
I think that then the mosfet is blocking anything! and not listening anymore to its gate.
When i cut the power to the mosfet and reengage it. it works allright again...
anyone any clue???
1) what happens if the injector (electromagnet) fires a high voltage to the fet???
2)the mosfet has an internal diode, can it be used parallel with the fet itself??
i mean if there is a flow of voltage trough the diode and i switch the fet on what happens then???
Tks
