Help...resistance rising!

[Joanne75]

Hi everyone--hoping someone can offer some advice.

The past few days, I have been running a mini protank 2 on.an iTaste mvp2. I typically vape somewhere between 3.7 and 4.0 volts, with a 2.5 ohm coil in the protank.

Last night I noticed that vapor was down to almost nothing, and flavor was really lacking...I checked the ohms of the atomizer and was getting 3.6. I re-seated the protank, checked again, same. I thought maybe the coil was just bad, so I swapped it out for a brand new one.

Ahhh....good vapor, good flavor and reading 2.5 ohms. By the time I went to bed last night (vaped for maybe 15 minutes on the new coil), it was reading 2.7; when I got up this morning, it was reading 3.0; and now it's reading 3.4 and vapor/flavor are nearly nonexistant.

I'm vaping a juice that I have vaped many times before with no issues re: gunking up the coils (it's clear and pretty high PG).

Any thoughts on what could be going on?? This stinks LOL!!

I'm guessing the 510 "pin" on the MVP is starting to recess a bit. Can you extend the pin on your tank(s)? If not I have to take a small flathead screwdriver to my MVP2 pin and gently pry it up every so often if I'm using a tank where its own pin is fixed.

+1 on Kodiak's advise. Here's a video to show you: Center Pin Issue - Fixing a non firing eGo battery

Clean the contacts really well too, we tend to overlook those easy fixes.

Awesome, thanks

Thanks everyone...tried prying up the 510 pin a bit (and it definitely moved upward) and no change--still getting weird readings on my attys. Any other suggestions?

 

[Joanne75]

Oh, and cleaned the contacts too

Try adjusting your coil a little. I was getting varying readings on my Aero tank. Took it apart and found that the coil had moved some; not enough to short, but when I moved it back the Ohms went down considerably.

I find that the ohms count goes up on my coils across a period of time as they get gunked up. Maybe try cleaning and dry burning the coil amd see if that makes a diffetence.

If I've done everything to trouble shoot it then I just assume its about to go and toss it.

Have you tried just turning up the voltage when this happens? See if it helps the flavor/vapor improve until you get a replacement or find a permanent fix.

If you can find another OHM meter to test on that would be good.

How long have you had the MVP?

Also, perhaps you got a bad batch of coils. I recommend buying them at 1.8 or 2.2 ohms as those seem to have the most consistency in my opinion. Bad batches of coils happen all the time.

Any time my resistance jumps around, there is always either a spotty connection or something is loose. Sometimes my R91% resistance would fluctuate, it's always the center pin has screwed itself up into the atty and isn't making a good connection. Sometimes the resistance in one of my RM2's fluctuates and it's always a post screw that's come a bit loose.

 

[Halcyon2501]

How long have you had the coil in use? Coils wear out over time due to fatigue from the wire repeatedly being heated and then cooling again. When this starts to happen, the resistance reading will rise like you're describing.

Might try getting the coil tighter in the Base. Loose = High resistance.
