How is an overstroke switch supposed to work?
When running at idle and I manually operate the ESA switch the engine stumbles as it should, however, whilst keeping the ESA activated and then activating the overstroke switch nothing happens ( the engine stays in "stumble mode") so I thought the o/stroke switch was faulty, so I got the manual and tested both switches with a multimeter as it said in the book, by probing the female plug with the four wires going in to it( 2 black, 2 blue)
The results were spot on to the book, but the male plug that goes into the female only has 2 wires coming out of it( I assume they go to the coil)
My question is, how does the o/stroke switch do anything to cancel out the ESA switch when it is activated, if there is nothing connected to the pins in female plug?
Also should there be 4 wires coming out of the male plug not 2?
Can anyone explain the working of it, should there be another 2 wires somewhere, if so where?
BTW both switches work as they should when tested
Any help or info appreciated
