MVP 20 WATT NOT READING OHMS RIGHT

[bman1977]

My MVP 20 watt recently started to get a little wonky on me. I use 1.5 ohm coils in an aerotank but for some reason the MVP is readin it as 4.9 and sometimes even higher. Of course its not hitting right either. I know its not the coils because if i put that same tank on my MVP 2.0 it reads correctly. The MVP 20w doesn't do this all the time but today its been doing it all day. It won;t go below 5 ohms and sometimes its even higher. Is this thing shot?

Have you thoroughly cleaned the 510 connector lately?

I don't have it with me right now. When I get home i'm going ot try that. I guess just alcohol and a qtip right?

Yes.

If that doesn't help, try some other attys to see if its just that one not connecting well with it, or if its the mod. It could have a bad solder joint or loose wire.

Yes, I know exactly what the problem is.


The MVP 2.0 is NOTORIOUS for having bad 510 connections. In fact, back when I used an mvp 2.0 I had to buy a 510 to 510 connector, and keep it on the mvp at ALL times, because after a while the mvp stopped reading several of my delivery devices.

The solution is to clean the 510 connectors,
if that doesn't work, try RAISING the 510 connectors.

If that doesnt work, youll need to buy a 510 to 510 connector like I did

Thanks. Ill try cleaning when I get home.

Ok so I cleaned it. Now it's giving me ohm readings of 7and goes up to 8. I tried a different tank and it reads spot on. Tried yet another tank and that one is spot on as well. Changed the coil in the one that I'm getting the crazy reading on and and the ohms jumped even higher. Is it possible that the tank is causing it?

Sadly, some tanks and mods don't get along.

But, it could be the atty. Does it work on other mods?

sounds like a poor connection problem in the 510 on the MVP

Not sure how the MVP 20 Watts positive pin works, but my MVP2, it wasn't unusual to occasionally have to pull up the positive pin for it to make better contact. I used a pick or small screwdriver to gently work it back up.
