Help to Turn on A5 E-grip W.A.S. board

[badger]

Inherited this 13 year old A5.
I have No idea how to turn this on.
Installed a new 9v, and held the trigger [micro switch] down. Nothing.
I put a meter to the, wire harness, micro swtich, and Cap. and all show 8.5 V.
I think it's a WAS board <?>

This is one of the awesome ones! That red pot is the on off and mode switch in one. The white pot is rof only. I think it topped out at like 10 bps or something, but its true fire modes. I'm pulling from memory here, but I wanna say like 1 is semi 2 is off, 3 is turbo, 4 off, 5 ramp, 6 off, 7 xxx, ect.

Thank you.
There is literally no documentation that I can find of this grip. A lot of composit but it works.
All my life I've been a Cocker guy [still am].
This is the first time I cracked the shells of a Tippmann.

The charging handle that sits on top, do yourself a favor and clip 3 rings off of its spring. It won't effect anything but makes putting the marker back together much easier

Thank you. Your Google-fu is strong!
If this has a market the I might put it up for sale along w the Low pressure kit.

Can I just say, this is probably the most MCB thread I've seen in a while.

Not making fun of you badger just the situation, I understand tippmann chose a really weird way to operate it

"It has batteries! Help I can't turn it on! "

About the only thing missing is someone telling you to try stock class instead

No offense taken.
This new tech is impressive but there's a Zen -the satisfaction of figuring out and rebuilding a mechanical marker.
One doesn't just shoot it, you understand the soul of it.

One does not shoot the marker. One must become the marker
