Hi Reoville

My apologies in advance for the long post. Silver Vein Grand just got delivered together with my RM3. Got a really weird problem with the atty and I thought I would check with all the REO gurus...

I'm looking at the atty and seeing the really tiny wire holes in the posts, I had a hard time believing I could get dual coils through those. So first thing I did is drill all the wire holes out to 1.2mm. Now I'm wondering if I screwed this atty up.

After drilling, I wind dual coils for the RM3, install and measure the ohms. Its supposed to come out to around 0.7 ohms but the multimeter says 1.5 ohms. Huh? Fire it up on a mech and only one coil is glowing. I check the coil tails and one of them breaks off. OK, I'm thinking maybe that's why I'm getting a high reading so I make and install a replacement coil. Multimeter still says1.5 ohms, and still only one coil glows. I check the coils again and they're both snug so I'm thinking maybe the negative tail on the non-glowing coil isn't making contact due to a faulty screw. I change the screw out, no dice, still not lighting up.

At this point, I'm thinking it cant be the positive post since one coil lights up. Right? So it must be the negative post. I decide to test positive and negative connections a pair at a time, using one coil. As it turns out, one pair of connections fires fine and the other doesn't. The bad side won't register a connection on the multimeter (says 1) and it certainly doesn't fire. I'm looking at the problem negative post to see if it somehow got loose but it doesn't even look like it's screwed in. I'm absolutely not discounting user error but I cant really figure out where the problem is.

Does anyone know what's happening here? I sure would appreciate any suggestions. Thanks!

Sounds like you have one negative post not making a connection at all. You can test this easily. The threads on the bottom of the atty are negative, so put one probe there and move from post to post. Post one (negative) ought to give a reading, post 2 (centre one - positive) no reading, post 3 same as post one.

If you are more inclined to use coils to test it - then put one coil either side of the positive and 'good' negative and both coils will fire. Repeat using the 'bad' negative and neither will.

Thanks for the quick reply guys

I did as you said, one probe to the 510 threads and the other to the posts. One negative had a reading of 0.5, the postive and other negative post had a reading of 1 (no connection). I tested with no coils on. Is it safe to conclude that the other negative post is not connecting to the rest of the atty?

yup. Specifically, it's not connected to the negative side at all, so maybe it's not screwed in - hard to speculate really. Try screwing that post in maybe?

Incidentally, if you have one good negative and one good positive, you can just put a bend in the legs of your coils and still run duals on your good posts, one either side, but it rather defeats the purpose of a 3 post atty.
