Help : Misfire on MOD

[antonmichal]

Hi guys - i have a puzzling situation :

i have a 26650 Vanilla Copper Clone powered by purple Efest IMR 3500mAh battery and
i wanted to test it out for the first time with my Veritas rda (dual vertical coil, 0.8 ohm).
The thing kept misfiring on me so i took the mod apart, checked connections and gave it a good clean
however this didn't help and it only fired about 1 out of 5 times ...

i checked my battery on volt reader and 7 out of 10 times it kept showing around 2.3 V and the other 3 times 4.17 Volt ....
i put the battery on my charger for a double check and that also showed as 4.17 and in a healthy state !

Now, considering my mod is new and so is the battery there is no way i could currently tell which one is causing problems.

has anyone experienced something like that before or would anyone have any idea whats causing such voltage jump ?
i suspect it is something with the mod but cannot pinpoint what could cause such abnormal behaviour

HELP !!

Get a reliable meter and then test. Sometimes meters are suspect especially the cheap ones. The probes get dirty as well make sure they are clean. Alcohol cotton balls work

Check the fire button and 510connector head are securely tightened.
Check that the positive end of the battery is making good contact good contact with the 510 pin. Some flat top batteries have problems in this area.
Check the firing pin is making solid contact with the negative end of the battery
Clean everything with alcohol

When you say misfire what exactly is it doing ?

 

[antonmichal]

@sparkky1 - you hit the fire button but coils are not heating up. Volt meter showed that the fire button does work but only provides around 2.3v only (most of the time)
so looks like i get only half the power... i'll try to give it a good clean once again right now

26650 Vanilla Copper Clone

The thing kept misfiring on me so i took the mod apart

has anyone experienced something like that before

As I recall... some have reported that their version (there is more than one switch assembly variation of a 26650 Vanilla Copper Clone) of the mod's lower insulator holds the battery negative up too high for the available button travel... with intermittent and/or no contact.

As there are two distinct button versions I'm aware of (maybe more) - one version (large OD insulator) can be effected by the batterie's negative surface, if it's raised or flush... while the other version (small OD insulator), less so.

Small OD:

Large OD:

Some have removed material from the insulator to "lower" the battery... some have extended the threaded contact upwards with a small washer, in effect "raising" the contact closer to the battery negative... to create a more firm contact. The former has no effect on button press resistance... the latter will.

Either way, the fast diagnosis is to remove the switch assembly and press the button... is the battery negative contact rise above the insulator? No - see above "cures". Yes - other issue.

@stateOFlux - thanks ! i have the first version (small OD) will play around with it - i have a feeling you nailed the issue i'm having !

Actually, EBates got it first... I just added a bit of specific detail. ;-)

Easy fix... hope that solves your problem.

The top cap pin sounds like it needs to be tightened.

These kinds of threads make me shudder...

and why exactly is that W-Rat ?
