Help with an Emag

[punkncat]

I have been trying to tech one of the PTP Emags for a friend who is a part of the forums.

Now given that my knowledge of an Emag is pretty limited, I know a few things, and am pretty decent with a mech, but this thing has me stumped.

So, here is the deal. The mag was working fine, the sear broke, and was replaced with a new one. The owner took loose the clevis (whatever) on the solenoid and just placed the new sear right in place of the broken one.

He brought it to me to look at and try to tune the LX a bit better. I cannot get the marker to fire properly at all. At first I was convinced that it was an LX problem because it would fire and the bolt would stick forward. I messed with it a bit and then the bolt will not move, so I put it back in its original configuration.
If you remove the valve and press on the sear, it clicks fine, seems good and strong like it should be.
With the valve in place it does nothing in E, or mech mode. This is the same with two seperate valves, and with two known and measured e mag on/off pins.
The battery has been charged.

What do I need to look for?

I figure even if it is a problem with the battery, or solenoid it should still fire in mech mode, but it does nothing.
I had thought that perhaps the trigger pin needed to be lengthened, but I know its pushing the on/off at least far enough to allow the valve out of the marker when you disassemble.

Help?

That's a doozy. Did you try transplanting the valve into another mag to see if it works? I would start by fixing the mecanicle mode first.

I actually think that is what I am going to do, is to take the valve out of the Emag and put in a mech marker, get it working on a stock RT on/off pin, get the LX right, and then go after it in the Emag.
I had considered putting in the Lvl 7 bolt just to eliminate that as a possible problem.

Yeah here is how I would attack that problem..

1. Ideally you have another E-mag to transplant the valve to, if not, transplant it to a mech and make sure the valve works. Since you tried a second valve, I'm assuming thats not the problem, but I would still start there.

2. Air Pressure good? on/off? What about the tank reg? ULT? Level 10 in working order? Check battery with voltmeter for those 16v? Oil? -- not gunna lie it seriously sounds like an air pressure issue.

Assuming all those things are how they should be..

3. Get out the calipers and measure the sear to AGD standards: http://www.niedtech.com/index.php thre is a manual there with pictures on how to do it.

If that doesn't fix it, you need to start looking at the logic of the situation. If you are using valves that you know work, then you know it has to be an issue with the lowers. If you cannot fire in mechmode you know it is an issue regarding the sear. Either the pin lengths are wrong, or the solenoid is the issue. And go from there..

And of course the standby - send it in.

One question - those PTP bodies are done to AGD standards right?

[punkncat]

The battery is 16 or 18v?

I am going to put that on a meter tomorrow just to be sure. As I said before though, even if that is the problem in Emode it should have no effect on mech mode.

As far as I know the PTP bodies are to spec. I know that before the sear issue that this marker worked fine.

Micro Emags need a differnt pin length, .67something its in a sticky somewhere yes that short. It will not shoot otherwise. in e or m

that makes sense, we changed the pin before I left last week.

[punkncat]

What happened with the original on/off pin that came in that?

Anyway, grab out your calipers, and we can make that happen assuming we can verify the proper length. Don't you have some contact info for PTP still?

Anywho, talk to you tomorrow Alex.

[punkncat]

LOL leave it to the stickies....

Micro-E-Mag on/off pin should be about .670-.675. Trigger rod lengths and stuff like that I just eyeball because MicroMags never seem to work right wih AGD tolerances

We should be able to get it going tomorrow assuming you have some way to shave the pin down or have the one that was that length.

Pin sounds like the right direction. I have some (too much if you ask me) experience with these things so if you need more help hit me up.

Did you guys remember to reinstall the spacer plate?
