Board/Eye problem

EclipseBaller · 01-12-2010, 03:18 PM

I'm not new to pbn so I know better to look before I ask but there was nothing listed in the stickies...

Picked up an Ion from my friend to repair it for him. Board turns on great with a fresh battery, light blinks fine. Turn the eyes off and try to dry fire, it shuts off. Same with or without paint or air. Is this an eye board/cable problem or main board problem?

You are just pressing and releasing the button, correct? not holding it?

Yes sir. I've worked on Ions before but never had this problem.

you using a brand name battery? Ions are really picky with that. Try getting another brand name battery from another pack and see if it solves the problem. Sometimes it has enough power to turn the gun on, but once you shoot, it shuts off.

Yeah, it's an industrial energizer. It still stays on, with eyes on, and pulling the trigger, but once something is in the eyes and trigger pulled, it's off.

Try it with the board out of the frame. It's possible that the button sticks, or something causes it to stay in for an extended period of time.

and make sure the connections to the battery itself are all good.

Connections are fine and i've tried it with the board AND eyes out and still having the problem. If I had a good set of eyes and cable I could tell right away. Where can I get them for cheap? or will SP replace it?

www.smartpartsparts.com should have everything, but www.punisherspaintball.com might be cheaper.

Picking up some new laser eyes on here. Have we diagnosed that that is the problem? They're worth the money either way but I'm convinced that's it.

I highly doubt the eyes are the problem. If they were the problem, it would show up as the gun shutting off immediately when the beam is blocked (or unblocked), even without pulling the trigger.

Does the gun shut off with the eyes on, nothing in the chamber (no ball), and the trigger pulled? If yes, then something is wrong with the switch (very doubtful), the board, or the wiring between the switch and the board.

Since it sounds like the gun only shuts off when it activates the solenoid, I'd start checking for a short in the wiring to the solenoid. Maybe even some dirt stuck to the backside of the board is shorting it out.

Brand new eyes didn't fix it. Once something is in the eyes it completely shuts off. I see no damage or debris on the board or any jumped connections. The ONLY mark is on the capacitor, it's very very minute, about an 1/8 of an inch scratch which I highly doubt would cause a problem.. would it? Any other solutions?

Sounds like it needs a new board.
Looking at the Ion schematic,

, there isn't much that can be making this happen.
From the schematic, the signal wire to the main board is high (~5v) only when there is something blocking the eyes. But, that 5v is through a 24.5k ohm resistor, so max current if that signal wire was shorted to ground is 0.2mA (0.0002 amps), not near enough to cause this problem.

So you're down to either the chip thinks the power button is being pressed (possibly when something jostles the gun), or something is shorting out the 5v supply and sending the voltage regulator into thermal shudown (which looks like battery removed and re-installed to the chip).
