Just wanted to chime in and get some opinions about an issue that my friend is having. He has an IPV 2 with a zenith and has a 0.6ohm dual coil build on it. Intermittently when hitting the fire button it will jump to 1.2 - 1.8 ohms with volts spiking concurrently and then going back down. Other times it will flash "check atomizer" and "check battery" I initially thought he was having a short so I instructed him to re-build it and change battery (both are VTC4) and he is having problems still. Since he has done all of that and all the battery connections and 510 connections are snug I am at a loss on this one. Anyone have any advice to keep him from having to fulfill his warranty already? Is it possible he has an internal short in his zenith not related to the coils? I will see him tomorrow and let him throw my IGO-w on there to see if it still happens but with both 'check atomizer' and 'check battery' going on I am lost. Thanks for any advice that I can pass along to him, I will see him tomorrow so if anything in particular needs to be checked I can handle that when I see him and report back in case anyone else is experiencing these issues.
Open the cover and check the ground wire that is at the top soldered to a screw. You will have to remove the sticker to peek at the 510 connection. The only reason you will get an off reading with your build is limited to a few different things.
1. The coil build to the posts in the atty.
2. The 510 center pin of the atty
3. The 510 center pin of the atty to 510 center pin of the mod
4. The 510 center pin of the mod to the circuit board
5. The ground network which goes from the battery to the circuit board and is paralleled to a screw on the inside of the box.
The is the only reasons that I can think of that would cause bad ohm readings. Well other than a bad circuit board.
If you have a meter you should be able to probe all of those things that I mentioned.
1. Install the build and make sure it is snug. Measure the resistance from the center post of the build deck to the white wire inside the unit. There is a little exposed silver part of the white wire so you should be able to hit it. ou should read as close to 0 ohms as possible.
2. Measure from the ground lug of the battery box to the outside posts of the atty. Again it should read as close to 0 ohms as possible.
If you get higher than say 1 ohm then you know your problem is on the positive side or the ground side. If on the positive side you can luckily half-split it to narrow down the problem. Remove the atty and measure the ohms between the center pin to the white wire. If it is good then your problem is the atty or the atty to mod connection. If if is not then you have a problem with the 510 connector (center pin)
Repeat for the ground side if it reads higher than 1 ohm.
For reference I read 0.2 ohms from the battery negative terminal to the negative posts of the atty, and 0.2 ohms from the center post of the atty to the white wire.
