Anybody good with merc's?

bad news guys i just switched both boxes around and i'm still getting no spark on the starboard. so now i eliminated the idea of a bad switch box what should be next on my trouble shooting?

if its not the switch box check the stator,im not sure how to do that but im sure someby will tell you

yep sounds like one side of the stator is out, you can ohm out the stator but i always thought that test sucked. best test to do is to DVA the stator but you need a special meter or an adaptor from cdi elec to do that. or you can ghetto dva the engine like you did just you dont get any cool numbers to look at. before you drop 300+ on a stator check the grounds and if they are good then thats most likely what it is.

is it hard to somehow remove the stator and take a look at it? i seen them on the internet for about 150$... if it isn't the stator or bad grounds what could it be.

Could be the power pack for that bank of cylinders.

Does that thing have 2 regulators or powerpacks that are controlled by the stator?
If so and if the part numbers are identical, swap them around and see if the spark problem moves to the other side.

i hate to say this but if i was you the good thing is its not working so it would be easy to find the bad thing is i think you should take it to a marine shop and let them diagnose it for you unless you can diagnos the stator yourself i replaced mine 3 times or the marine shop did it you need special tools also it would be garranteed by them could be a bunch of things

I would reccomend you wait for Bigshrimpin to pop in. He sold me some MERC parts for one of mine a couple weeks ago. Plus he knows the MERCS. The bare minumum though you need a peak reading volt meter, or a DVA with a PRV adapter from CDI.

Sure sounds like a bad switchbox to me. No spark on one side is almost a dead give away. Make sure they are both grounded. If you 100% positive that your didn't make a mistake swapping them . . . then There is a test for the trigger and stator in the manual using a multimeter . . . You won't have to pull the flywheel to test them . . . just disconnect them from the switchboxes and check for continuity . . . specs are in the manual. If you need me to scan some pages . . . . I can do it. I have TONS of 9/16amp merc parts, so don't go buying anything new. I have 30+ switchboxes and several stators and triggers for that engine.

How's the wiring (harness to coils, trigger wires, stator wires)?

I have a flywheel removal tool. I'll be going through RI on Tuesday if you want to borrow it for a few hours :) I'll bring a couple of stators too. It's EZ to swap them out.
