That service bulletin is from Mercruiser, not Volvo.

Hi Don,
Just noticed that too, but I will do the voltage checks at the coil and the grounds, etc.

It's also for a MEIF 3, not 4 like Volvo is using on your B model. Completely different, so don't even try to use it. Use the manual I gave you, it's Volvo and the proper year.

You don't have that kind of coil or ignition system either. You are listening to the wrong info because it sounds easier :facepalm:

OK noted, breakfast time now. Will do your purple wire suggestions and the grounds and let you know how I go.
Thanks, Allan

So after a few hours baking in the 35 degree Brisbane heat.....check out the pic, this is where the purple wires join on the back of the trim gauge (of course the last one I got to). As soon as I started moving wires behind the dash the pumps started buzzing / the buzzer beeped etc. The nut was loose and the yellow line highlights how loose this contact was. And the nut had seized on the stud in this position, so the wires had been like this for the near 2 years I have owned this boat. I am surprised this thing ever started. I took it out for an hour to test drive it in 25 - 30 knot winds and bay chop and it did not miss a beat.

So above all - thanks to those who sent info and posted suggestions - especially to Don who's purple wire suggestion was the culprit!!

Glad it was an easy fix without a few 1000 more going to your dealer.
