Vamo cuts out after firing, resistance all over the place... bad coil? (sanity check)

[LeoRex]

Rinsed out my evod, just ran water over the coil and sat on a paper towel to wick out what was in the coil... threw it on my new Vamo V3 and vaped away. About an hour later, I go to vape and it fired for a couple of seconds and just petered out... Did the same a second time. I re-seated the evod and checked the resisitance and it was showing as like 4.9 or something (these were 2.4 ohm heads). I checked the resistance a couple of times, all different values, even got a 9.9 once. I checked and the leads and battery post looked dry and perfect... no issues.

I've had the evod two days, naturally I kind of freaked a bit, thinking it was going t'd up...

But I threw a new coil on the evod and all is well again.

Sanity check.... Is this a sign of a messed up coil, like a loose or broken wire that was making intermittent contact?

make sure the coil is tight to the base

Possibly you have smashed the grommet in the Vamo. Check the Vamo forums for possible fixes.
Also try slightly lifting the center pin
Also - The evod coil could have been slightly loose causing erratic behavior.

I just picked up a couple of evods and neither of them work on my Vamo. They work fine on my Evics and Ego batts though.

If yours WAS working, like the guys said above, be sure the atty head is screwed on tight.

Almost certainly a bad coil. I had a similar problem with a Kanger MT3. The battery would flash and refuse to drive the tank. Replaced the head and all was well again.

Thank goodness for battery circuitry that detects a problem with the coil and refuses to fire.

I've had a couple of new heads do similar things on the Protank. I'll fiddle with it for a few and if it doesn't straighten out, I toss the head and reach for another one.

First
99% no fire is center pins Not reaching each other to close the circuit. Pull device pin UP or Evod pin down

Second
Coild inspection is simple. Pull pipe from Evod coil(easiest when on base) pull 2 top wicks Look at coil. Look for broken coil(open) or coils touching each other or tube(short)
Adjust with tooth pick if needed.
Test with battery and 2-3 second burst. If starts to glow, good to go. Re-assemble

Do exactly what it says in this guide: http://www.reddit.com/r/electronic_cigarette/comments/17ai9i/low_ohm_reading_on_vamo/c83uj18

My Vamo had this same problem 3 days after I got it. I figured out I tightened down an evod too far which caused this issue. After following the instructions in the guide above it fixed my problem and hasn't given me a bad reading or misfired since. It's been 2 months now.

yeah.. had to have been a bad coil... I'll tear it down when I get the chance to see where the issue is. But it was a well-used coil... a couple of weeks, at least, of daily use and occasional cleaning. I did take a close look at the center post, but it looked like it hadn't budged since the day I got it.

I can only assume that when I do an autopsy on that coil, I'll find that something... one of the legs, part of the coil... is messed up or snapped... something that causes intermittent contact and shorts. To me, this would explain why it would fire for a few seconds than trail off, then not fire at all, then show resistances all over the map, etc.

All I know is that a new coil worked fine. Phew... I was surprised at how much better performance I get out of the V3 as opposed to the Spinner I have, I didn't want to have to start triage on it so soon.

I have the exact same problem with on a t3.
I guess it's a bad coil.
