Anybody good with merc's?

i would agree switch box you have two of them one for the left side plugs and one for the right side its easy to replace could also be the stator but sounds like switch box to me

Knock on wood, my MERC has been trouble free. If I had to guess I would say switch box though. Common problem for the MERCS to lose em. RAPAIR/CDI is regarded as being the better replacement for the switchboxes.

thanks guys for the quick response. i didn't know the switch boxes were interchangeable.. that will definitely be my saturday morning project, switching them around. i'll keep you guys posted. thanks again!

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?

[steplift20]

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.

boxes sounds good, still sounds like the stator. it probably isnt the trigger because that usually would give you two dead cyl, one on each bank. and if you still want to be sure bring it to a shop and tell them you want them to put their meter on the yellow wires tell you what they find. they probably wont charge more than 50 dollars.

bigshrimp, im going to try this in that link you sent me

No fire on the 1,3,5 or 2,4,6: Swap red and red/white wires, also blue with blue/white wires. If the problem moves to the other set of cylinders, the stator is at fault. Disconnect rectifier and retest. If the engine fires normally, replace the rectifier. If no change, we recommend replacement of the stator. If you replace the stator and the problem remains try another flywheel, if possible.

I'm a bit confused. does this mean i leave the whites and black/yellow stripe alone on both switchboxes. and switch the reds and blues between the 2 switchboxes?

If thats what there telling me to do it seems easy enough. i just want to make sure 1st. thanks again.

sounds right, what they want you to do is swap the leads comming from the stator around from one side to another.
