Trouble with my Grande and SLR

[Cjax]

So I've been rocking my Grande for 3 months now and absolutely love it. It's definitely the thing I go to whenever I walk out the door. Couple days ago it started giving me problems. Lots of misfires. I followed the cleaning instructions in the sticky thread (wash with hot water, took an emery board to the firing pin, and just a dab of noalox), and I'm not getting any more misfires, but what I am getting is sparks, lots of them from the firing pin to the top of the battery. It looks like a light show underneath the delrin cover. To be totally honest, it could have been doing this for the entire 3 months I've had it, I've just never noticed it until it started misfiring.

Now to answer any initial questions about this, let me say I'm using an A7, and the center post is nice and tight. My coil is a 3/4 wrap of 28g and meters at .7 ohms and my batteries are all high drain IMR, with at least a 10 amp continuous rating. I'm using both nipple and flat top batts and either one will get hot, but just on the top (positive contact) of the battery. I use this same set-up (same battery and atty) in my tube mod with absolutely no issues (I've been pulling the battery out after chain vaping to compare).

Is this normal? Does anyone else running similar ohms see the same type of electrical arcing from the firing pin? I'm not too terribly worried about anything venting or anything like that, but it could happen (?) and I don't want to fry a spring from the battery getting too hot either. I haven't used my Reo since yesterday and I'm jonsing for my feeder back, dripping on a tube mod is so messy!

Ha ha, just read a post about this same thing. Should I use more noalox on the firing pin to ease down the arcing? I'll try it anyway.

I dont think an emery board is enough. Use a good nail file on the rough side and put some pressure on it. Then a dab of Noalox.

^^^^what he said. Give it a good filing with a little more pressure than you might think you need to with a metal file....then add Noalox. Should take care of the sparks.

Ok, thanx. I'll take it all apart after dinner and get in there and show it who's boss!

Just pull the battery, press on the firing pin to expose the tip and file it. No need to take it apart.

The sparking has effects on the battery's surface too. Check that, clean it, metal polish (?) Also, here's this.

had the very same issue with my grand. a week after receiving mine I started to have all the same issues as mentioned above. I also read the maintence records and sanded the tip, also adding the noalox. this totally stopped the issue until a few days later when I stated once again. because the reo was new, and was my first one I thought it was a misaligned firing pin. I sent it in and nothing was actually wrong with it. I believe this to be an issue with ultra low resistances, well maybe not an issue but something that requires more maintenance then a higher resistance coil. I am going to up my resistance by 1 ohm and see if it makes a difference.

Unfortunately a 1Ω coil on a mech just doesn't cut it for me. .8 is good, but .7 is better. Now if I could just get off the couch, but the nail file is all the way upstairs! I gotta do it tonight, cause I don't want to be at work tomorrow without my Grande, I'm just having a lazy moment.

I run a . 8 all the time and I dont have the problem . I clean it every two months weather I need it or not . I am curious to see if running lower ohm coils requires more cleaning

Here's another thing. New batteries . . . . having just played with that worthless circuit writer pen . . . . I notice the AWs have a coating (a fine gray seal on pos. & neg. contacts) . . . old batteries, bottoms, "oh, look, there used to be a coating, can still see it on the edges".

Anyway, those batteries were in tube mods. Especially the "telescope", where you screw it shut to make contact . . . (screw, screw, screw, rub, rub, rub, month 1, month 2, month 3 . . . . .) . . .. Am I rambling on?

Ok, the deed is done, and it'd back to bottom feeding for me! I may not have had to take it all the way apart, but popping the screw out and turning the firing pin outside the doorway sure made it easier to work, especially since the rough edge of the metal file I used wouldn't reach the pin without opening it up. I'm back to .7Ω bliss and the only fireworks I'm getting are from the satisfying vape this thing puts out. Thanx to all for the tips!

Yeah, pdib, I took a look at the top of my batts and noticed there was some small black marks on those too. I just hit those with the emery board a little very carefully, just to make sure. I'll check the rest of them tomorrow.
