Ohm Meter bad?!?!?!

[Krazirob]

This may be the wrong section but wanted to ask some of the veterans out there.......

I have been having shorting problems on my mod and it only shorts when I attach the 510 volt meter.......are those supposed to have any internal resistance? and if not how can i test it out to see if it is the reason why my mod keeps shorting.....

When i attach my atty it fires fine but as soon as i attach my volt meter I get a short and pop my fuse......

Thanks in advance for any help

Correct me if I'm wrong but it sounds like you're trying to measure ohms while the battery is in your mod. An ohm meter is only designed to operate on a dead circuit, that is with no battery or other outside power applied.

WAit.. are you hooking up your MOD or your ATTY to the meter?

You should only be hooking up your atty (the one with the coil on it).

.... .... ............wow i was in a hurry......i was talking about my 510 connection VOLT METER.....HAHAHAHAHAHAHA.........wow i feel embarrassed...i was thinking ohms because i was asking if the volt meter was supposed to have resistance.......

I don't even know how to respond except with a I'm sorry i have a idiot moment there....LOL

That makes a bit more sense... It would sound that you have a short being caused by the volt-meter's connectors. Try without any atty connected, just connect to the mod, see if that gives you a reading. If so check the connector on tha atty side to see if the insulation is damaged. If no visible damage attach an atty to it, but screw it in very slowly while checking the voltage. It may only short out when fully screwed in.

i did...this was happening without the atty connected.....it was just the volt meter on the mod.......

 

[Rickajho]

What mod and what atty?

 

[Stosh]

The next step would be taking an ohm-meter and checking the ohms at the connector on your voltmeter that screws into the mod. A voltmeter should read a very, very high resistance, sounds like yours is not, may read a short right there.

i have done that and it doesn't read anything.....it like there isn't anything connected at all.......im thinking its the voltmeter but can i confirm that being that the ohm meter doesn't get any reading at all when i connect the voltmeter to the ohm meter?

What mod and what atty?

mod and atty are irrelevant as i stated the mod and atty works fine with attached....its only when the voltmeter is attached where the problem starts.

My original question was only wondering if the voltmeter is supposed to have internal resistance or not.

Yes, and a very high internal resistance is normal. Strange that you aren't getting any ohms reading, should be in Megohms. Have you reset the ohms scale on your meter?

ok I'm back home and not using the 510 ohmmeter to get a reading.....im using my actual multimeter and I'm getting 9.40k ohms on the voltmeter.....but when i connect to my mod it shorts out the circuit but when i connect my atty everything is fine......so something is definitely wrong with this 510 voltmeter

Think I read somewhere that your coil must be above .6 or you could fry the voltmeter but you are popping the fuse correct? And this is with the Reo?

 

[Krazirob]

ok guys i found the issue......i have an 510 connector extension on the voltmeter and thats the piece that was causing the short.........took off the extension and put on an ego adapter and viola its working again.......

wouldn't matter what my coil was at cause there was never an atty attached when the voltmeter was shorting out the mod.........when i attached my .4 ohm coil it would fire just fine.......

so with that being said everything is working after 10 fuses.....HAHA.....thank god for the fuse mod!!!......

and thanks for the responses.
