Yes splice 105 as the red lead IAC enters and your fault keep showing IAC. The bad IAC caused the fuse to blow. Hopefully I helped with some info here as I thought something in B7 or splice 105 was shorted or bad connection. I have to ask I thought you ohm tested all the leads found nothing to be opened or shorted. A blown fuse would have shown a open circuit. Anyways just asking cause really I am surprised that I missed the fuse totally. I am glad you got it fixed and a good job on your part. A lesson learned for all.

Oh also thank you for keep reposting all important info and the final fix.

See I belong to a marine tech org only that is world wide and our forums are somewhat different than here as if the tech with the problems never updates us he is basically looked at to never help out again unless he posts everything including updates that he did including the final fix.

BUP, i had continuity thru the green wire to the IAC. The thunderstorms stopped all progress from there.This morning I got the wiring diagrams and determined I should have power at the red wire tn the IAC connector which I did not.Checked the working engine and I did have power. Went back to the wiring diagrams and went thru the circuit and found the fuse. Opened the cover and BINGO.Thanks Again.


Power at connector with key on!

Rich sorry my bad I thought you checked the red wire already. that's what thru me way off. Ok no big deal really glad you found the problem without a huge expense. Thanks for the all of your posting another job well done on your part.

BUP, sorry to throw you off. Electrical was never my strong suit and articulating it over the computer is not easy. Nice working with you.
