Motor stall beyond 3000 rpm-cuts out

[spareparts]

its hard to do a running test with out the engine being loaded, you would have to use a test wheel, a dyno, or hang off the back of the boat while some one is driving. I usually just check it at cranking speed, pull the plugs out, set up a spark board and spin it over, it will usually show up

OK, I will retest at cranking and check the readings. Thanks!

Ok guys, with the bias wire between the switch boxes disconnected (BTW this is a 16 amp flywheel) and plugs out, these are the new max readings to ground with the DVA:

blue=217v
blue/white=222v
red=53v
red/white=53v

Trigger check
wire read to / resistance / dva connected / dva disconnected
brown white 1248 / 5.26 / 5.20
white purple 1268 / 4.81 / 5.77
purple brown 0 / 1.52 / 4.56

According to Mercury CDI trouble shooting, since the readings are within specs when disconnected, the trigger is good and the pack(s) are bad.
What do you think?

sounds like a switch box, if you replace one and its better, go ahead and replace the otehr one, it won't be long before it takes a dump as well
what was the outputs on the green wires?

[BuilderFL]

Spare, did not check the green wire. Didnt see it in the troubleshooting or just missed it. Will do tomorrow and report back.

[spareparts]

green wires, they are the outputs from the switch boxes to the coils, that should tell you the output voltage

Had a chance to take the boat out yesterday and the motor performed perfectly. I had some spare power packs that I had gotten from bigshrimping back in 2007 and I replaced both of them, even though only one was testing bad. Problem solved!
Thanks Guys
