MS3 pro issues

I have 2 issues I am trying to figure out....Everything else looks like its good to go.

1. When testing spark output, I can get the leading coil to fire on A, but then it fires again on B....even though there is only 1 wire going to the trailing coil. If I do the "sequence" mode all of them fire. Is this normal because of the "rotary" mode? bug maybe?

2. I get nothing with the idle valve when testing, however I need to check that it is getting positive power. It might not be getting any

how are you confirming spark?

spark B could be getting grounded by the leading coil and jumping back through a leading spark plug

try unplugging the trailing coil and testing B and see if anything happens.

What are the odds...

From your build thread:



I re-tested and it does exactly as that says. A and B fire leadnig, then C and D fire the trailing individually.


everything has tested successfully EXCEPT for the idle valve. I followed Aaron's guide and I'm curious if having the diode backwards could have messed something up in the MS3pro? The valve does not work when testing, however if I take the valve and put a positive and negative connection to it the valve moves as expected. The banded end faced the positive wire, and the non banded end was attached to the PWM idle 1 wire. I got nothing. Then after reading closer Aaron's guide says its not REQUIRED. So I pulled the diode out and still got nothing from the valve. I tried a second valve as well and that did not work either.

I have verified there is 12v on the positive wire, so I'm not sure what is going on. I can post my MSQ if that would help.

are you sure you have the right output selected?

maybe re-pin the MS3 side connector and try the PWM2 output?

I temporarily ram PWM3 and that worked. Very strange. Going to reinstall the diode and try again. How do i pop the pin out of the connector? it would be great if i didnt have to re-run the wire.
