I am about to go insane and need some assistance. I have a few other posts as I have been figuring things out. I have a Mercury SportJet 175xr2 Power head. The previous owner to me changed the switch boxes and apparently switched them to outboard boxes. The season before last I had a new stator installed and at that time they did the trigger since everything was apart (Merc certified friend no cost on labor for me). After that we did have some timing difficulties but got the boat running good. Last season did the key switch and since the prior owner did some hack jobbing we replaced the harness with one that was not hacked to shreds. This season I got very low power output and checking found I dropped spark on one side of the motor. The switch boxes had not been done and from swapping them back and forth it looked like one was bad. Got 2 new boxes and installed. I tested before bolting everything together. Bolted everything back together and no start. Checked and no spark on one side of motor. Did some testing and finally tried swapping stator leads. Problem follows the stator lead change... What the heck. Talking to my friend he felt there was no way just in putting things together even if I goofed somehow it would take out the stator. I am really at a lose. Troubleshooting shows stator leads swap means new stator but I just don't know how it would have gone out. I'm hoping to get some input here and anything else to check besides the cdi guide that could have caused my stator to be taken out if that was the cause.

PS - I did talk to CDI and confirmed 100% that the sportjet switch box and outboard box is identical internally the only difference is the wiring connections (bullets for sportjet, rings for outboard) and the sportjet box is more sealed for the potential of water getting to it.

OK Update just went out and did a DVA test. CDI says DVA should yield Low speed 180-400 and high speed 25-100 volts. I get that a stator is the item I should replace unless anyone has any other reason it would not be however what I want to figure out is what would kill the stator so I don't have this 2 weeks post my stater change? Trigger tested within proper range just as an FYI.

Yellow side
High speed - 29 volts
Low speed - 195 volts

Black side
High speed - 24 volts
Low speed - 5 volts

Stators fail due to rectifier problems(overheats windings) beat and banged around during repair and if its got the external ground wire a ground issue
