Do you have a voltmeter? Set the Vamo on the highest voltage or wattage setting and measure the center pin voltage. It should read about 6 volts. If it reads around battery voltage (3.7 - 4.2), then you may have a ground problem or possibly a bad circuit board.

This is what my Vamo reads on my TR001 mod... it reads the same with my voltmeter...

The ground to the circuit board is brought in by wire soldered to a screw in the Vamo head. Sometimes that screw gets loose, gets corroded, or simply makes a bad connection. It may sound weird, but you might try whacking the head area a little to see if it makes any difference. You may cause the ground to improve and at the very least give you a hint of what might be happening. Don't whack it too hard! And yes, I've seen this problem before.

Good luck!

Thanks for the replies everyone, I'll try some of the suggestions out.

To answer a few questions: It's like this for all three batteries I have, the connections seem to be good and my cleros work on my back up.
But there might be something to the burial ground thing.

I don't have a meter, but I'll try banging it.

If that doesn't work, I'll take it a part.

I'll update as soon as I find anything out. Thanks again.

I tried taking the top off a few days ago and that sucker is stuck on pretty tight. I used a bench vise and I couldn't get it off for the life of me. So I either will be ordering a new one or a different brand. Are there other types of AVP's that I can use the same batteries as the Vamo? I'd hate to have to buy a new set.

I'm pretty disappointed this broke without suffering a hard fall or abuse.
