emag xmod 1.8 question

[BigEvil]

Amps are the big thing with the batteries and that is tough to measure easily.

[knownothingmags]

so the board turns on. displays the xmod 1.8 message.
and after using the best battery I have.
it is not engaging the solenoid anymore.

and I adjusted the magnet in half turn increments from all the way turned down into the trigger to almost all the way out of the trigger.

so, that's kinda funny.

I have yet to check the grounds at the board and the ground pin up by the battery.
and the wires I need to check to make sure everything is still attached where it should be.

if you check the grounds, wiring, etc. and everything seems to be OK, here is another spot to look for a potential problem:

The plungers would naturally bend a bit through the cycling process. The best way to check for a binding plunger is to remove the valve from the gun, point the barrel end of the gun straight forward (so gravity is working to pull the plunger down) push down on the back end of the sear (part that contacts the on/off valve) and then let go and the sear should fall down and the back end of the sear should be all the way up. If it doesn't the plunger is binding in the solenoid and bending the clevis rod a bit will get it back in alignment and the solenoid won't have to work as hard to pull it down. Solenoids do go bad, but very rarely. I think I replaced maybe one or two in my time teching E-Mags...

ill add that to the list.
makes me sad that the marker went to bed great and now its being difficult.

what, did you forget to whisper sweet nothings into your 'mag before you went to sleep?

Sounds more like its acting like a wife than an Emag.

Make sure the HES plug is fully engaged. The tiny wires can also become an issue if you remove the HES and plug it in quite a few times. Perhaps one of the wires broke. You can simulate the HES by shorting the middle wire to ground. You can also test the HES function by measuring the voltage at that middle pin. It is 5Vdc when the HES is not within the magnetic field and goes to 0Vdc when you pull the trigger and the magnetic field is sensed by the HES.

true true. :P
ill try that too. tonight got busy.

the reason this is a hurry up and get perfect fix is because someone here is interested in a purchase.
after a recent buy of the #3/13 xmag i just sold i will not let another mag leave my hands without it working perfect.
add to the list of checks****

aha,


here it is shooting properly now, just double shooting.
im guessing its because im using a gold spring, I prolly should switch to a red?

the spring shouldn't have any thing to do with it. is the solenoid tripping twice? like, can you pull the valve out and hear it double-click? does it do this in mechanical or hybrid mode? is the board still on semi-auto?

its on semi,
and it doesn't do it twice with the valve out.

What is your fix at?
Is the trigger rod hitting the back of the trigger? I always back them out a bit shorter than spec because with Xmod it bounces.

Also, adjust the trigger pull to be a bit longer. After watching the clip on a monitor its hard to tell but the trigger looks real short. Also - how is the magnet above the trigger shimmed? Dont shim it any more than one oring.

[athomas]

If it is doing it with the valve installed but not with the valve out, it may be one of three things. (1) Trigger bounce. (2) HES retriggering (3) A leaking on-off area.

- Make sure the trigger rod isn't hitting the back of the trigger.
- Make sure the trigger is stable enough that it isn't bouncing due to the valve firing. You may need to make the upper trigger magnet stronger.
- The collapse of the solenoid field may retrigger the HES if the trigger is in the right place. You might mitigate this by changing the polarity of the solenoid. You can check the polarity of the solenoid by placing a compase at the base of the grip frame. As you pull the trigger and the solenoid engages, the north tip of the compass will point away from the grip frame. See pic:solenoid orientation.jpg
- make sure the on-off orings are good and that the pin is working properly.

The on-off is probably not your issue and can be verified if it is working ok in mechanical mode.

Increase your fix value above 35 to eliminate the HES retriggering issue if that is causing an issue and the solenoid is wired properly.

[knownothingmags]

awesome I think with these two new posts, ill get it fixed I have a feeling I know whats going on now.

[knownothingmags]

AHA FIXED
boils down to a bent plunger rod, who would have though such a small bend would be such an issue,
couple that whith a low battery I was using, and the fix on Xmod was too low so it was bouncing, and I shortened the mechanical sear rod some.

yippy. I knew I could hammer this out with your guys' help.

that's what I get for only buying and never playing with my markers.
you don't use it you lose it.

[Cyco-Dude]

nice. now all that's left is to take it to the field for a proper test.
