No joy still, and a bunch of dumb questions related to bypass valve and ME-SFI
I re-soldered the MOSFET but I'm still seeing the same result - one weak revolution then the SC disengages.
I found a procedure for "resetting the bypass valve", but it's unclear exactly how to do it. Supposedly this is in SSM - can any of you with SSM find this procedure? It would be nice to know 1) What position the valve should be in to start the procedure, 2) How far I'm supposed to manually turn the valve with my finger, 3) At what point I'm supposed to remove my finger, and 4) What I should expect to see if it works as expected.
(I'm also not sure how the reset procedure knows that I'm holding the valve with my finger -- is there some sensor that tells it this?)
Also, if anybody has a wiring diagram for the 99 ME-SFI - that would be most helpful too (so I can diagram what *all* the MOSFET's are for, not just the one MOSFET for the SC clutch).
