Okay, Failed Coil Question

[TamiP]

Thankfully I was using this on a vv mod and it caught something I still am not quite sure about.

I was using the coil I had mentioned in the last thread, the 1.9 ohm single coil with the vamo v5. It was working fabulously for all day long, and I was vaping away on it, and then suddenly a few minutes ago the vamo stopped working and said "check atomizer" on the display. I don't see what's wrong with it at first glance, I'll tear it apart later. There's plenty of juice in it, and nothing looks burnt or "blown", but still, I'll look later.

My question is this.... I would not be aware of any problem at all if the apparent short circuit protection cut the vamo off. How in the world do you know if you have a problem when vaping on a mech? I mean aside from something glaring like a severe burnt taste, or a flame shooting out of the atty, (okay that's extreme) but how would you be aware of a problem like a short circuit if the atty had been reading a consistent 1.9 (or whatever it was wrappped for) on a meter all along, and vaping normally all along, then suddenly shorted? Is there something I should have noticed that I didn't?

Asking because I have a mech coming (hopefully) next week (slow boat from China)... and this kind of threw me. I would never have known (that I know of) that there was a problem if the vamo hadn't just stopped and said so.

when you're using a mech the two major signs that you have a problem with your buildare the mod will get hot or will not fire. There are other signs but those are the two big ones

Thanks... Im still wondering what is going on with this, I guess I'm going to have to put my work aside and tear the build apart to look at it. The vamo didn't get warm, or anything. Too bad they can't make one that actually tells you what is wrong with the atomizer besides just saying check it (lol, I'm not asking for the moon or anything, hahaha).

Fairly new to mechs myself and experienced the kind of thing you're talking about yesterday. Vaping away, everything fine, and all of a sudden it just... tasted funny. Not burnt, not metallic, just weird. Not wanting to try to fire it again in case it was a short, I immediately took the atty off my mech and stuck it on my ohm meter... what had been a 1.4 coil all day long was suddenly metering at 4.6... then 2.7.... then 5.0... I popped the top cap off and grabbed a screwdriver. The positive screw had backed itself out a quarter turn and was causing a poor connection. I tightened everything down again (immediately getting my 1.4 reading back) and was back in business.

So in addition to the "button shouldn't get warm" rule of thumb, there's a "doublecheck resistance if it tastes funny" rule of thumb.

These are all excellent points and I'm really glad I read this thread; I just got my first mech today, a Fallen Angel (EA Mod clone) and it's nice to know what to watch out for!

Thx y'all!

Repeated heating and cooling cycles will often work screws out of RDA/RBA...

Well too bad I changed the coil out (it didn't look 'damaged' in any way, it wasn't touching anything I could tell... but I changed it out to be safe anyway) before I read this. It might have just been a loose screw.

Well DANG... lmao... perfectly good coil that was working well all day, and it might have just been a screw loose (I've had that said about me plenty, now my coils have screws loose too. egad). Thanks for all the info! I'll know now to try fiddling with the screws before tearing apart what seems to be a perfectly good, and new coil.

THANK YOU
