So I filed a ticket with W9 and called them but had no response. So, I'm hoping someone here can help me troubleshoot my sr71.

My sr71 reads at 1.72 ohms according to w9's ohm reader. I'm still convinced that it's the white rod that got burnt after disassembling and reassembling a bunch of times. Pics attached.

Can someone please confirm or deny that it's the white rod? At least I can order another rod and get my sr71 up and running. I've iso bathed it a bunch of times already and the black does not wash off.

I just want to find out what's wrong at least..

If you have a multimeter you can test the resistance of the rod by touching the black probe on the metal part closer to the burnt looking side and touch the positive on the bottom metal on the rod. I don't think you can burn out that rod so easily. test the rod on its own though. You should get around 2.0-2.1

Are you sure it's burnt? If so, that is an amazing feat my friend. If it's fixable, run it dry without the coil to get rid of the black shit

1.72 on the tester = Perfect.

You just have to run it dry to clean it up.

If its not working then something else is the issue not the rod as the rod reads perfect.

Thanks a lot Gary, @konmo and @DaNi_DuB!

Isn't the optimal ohm reading for a sr71 1.5? (or 2.5 on the w9 ohm meter).

My sr71 had a reading of nearly 2.3-2.4 when I first got it.. Should I be concerned about the change?

Electrical reading are not set on stone. They can vary a little since electricity can hAve many variables. As far as the sr71 reading above 2.2ohm, this usually indicated a faulty connection. Causing increased resistance reading.

Ya I wouldn't be focusing so much on the reading if it wasn't for the fact that my sr71 doesn't fire at 7.4v with batteries, but it does with the core.

But it does fire at 3.7v with 1x 18650.

I'm just caught in this dilemma of... The Herc technically works but I'm scared to use it cause I know some thing is wrong. I know it's the Herc itself and not the persei but I just can't figure out why....

Maybe a bad battery? Have you checked the 18350 individually?

The 2x 18350 fires with the kiss cart and my nitecore charger charged it fine.. :\Other than that I don't know how to check them. But I do have a set of other batteries coming.

so your herc wont fire? what batteries or i should mean what brand are you using? the ones that came with the Persei?

Yah, the ones that came with the persei.

The herc won't fire with the 2x 18350. It fires with 1x 18650 (aw brand from w9) and the core from 7.0 and 7.4, I've only tried those two settings.

The persei and kiss cart fires fine with everything.

theres your issue, the stock batteries work with the carts not the Hercules. The Hercules requires AW 18350 batteries to work.

Lol... Well I'm glad it's that simple :lol: good thing I got some coming soon.

So it's ok to run the herc at 3.7v with 1x 18650 in the meantime? I was a little thrown off cause the instruction manual for the core said "minimum voltage set: 6.4 and max voltage set: 7.5" for the sr71?

It's fine to run it but.. is it even heating up at 3.7v? Unless you have the black rod..
Stacking 2x18650 would make it 7.4v with the SS kit and make it last around 3x longer than 2x 18350, just FYI, if you have the kit.

Yah it's on the list of my next order to w9 lol. It's turning into an early Christmas for myself right now :lol:

Thanks for the confirmation that it's safe, I have no idea if it'll get hot enough but I'll try...

And thanks @THC SCIENTIFIC! Appreciate the time!

On a 3.7 kiss gr2 will a 35 amp 18650 wreck the coil? I plan on just running my neglected 18350s but i was wondering if anyone had a definitive answer for me before i couldnt resist doing so.

No 35 amps means it's capable of providing that current when needed but it won't provide it unless required.

Are kiss carts known to leak as well? Oil seems to be leaking from the center screw under the cap. Do kiss carts require the same hitting and cooling method as the herc?
