Have you replaced injector drivers in your SBEC or SBEC2?
I developed an easy procedure to get them off the board that I will write up shortly.
First does any one know what to replace these with.
They appear to be a 5 pin TO-220-5 MOSFET of some sort. Is something for peak and hold?
The V6 uses a standard TO-220-3, the 3 pin N-channel MOSFET. I was able to identify this with my "transistor tester" with a Vgs of 1.4V
