shorts

[Zutankhamun]

I read this:
''Short doesn't always occur in the atomizer, test the unit itself as well. To do this with a multi-meter, take out your battery, with one probe touch the positive pin of the mod and another on the body. If the meter shows any kind of resistance, it means the current is flowing and you have a short somewhere.''
Could somebody explain this to me please. Am cool with building and battery safety but I don't understand this. Finally want to start using my mech tomorrow but better to be safe than sorry. Thanks

Basically this is checking to make sure the positive pin is insulated from the rest of the mod. If resistance is showing then there is a pathway for electricity to flow from the pin directly to the mod body itself. A short. Likely problem would be the pp insulator.

K thanx. I have a rubbish dmm which shows my freshly charged batts at 4.13. I know, You get what you pay for. I am a total noob with mutimeters as well. What setting should I set the dmm to to check this. The same 20V setting to check battery voltage?

In the OP you are trying to measure the resistance between the 510 pin and the body (ground) of the mod. Set your DMM to the lowest resistance scale, then touch the meter leads together. The meter should read 0 ohms. This will verify that you are reading resistance. Now test the resistance of your mod as stated in the OP. If the mod reads anything other than open your mod has a problem.
