isn't the battery positive hooked up to center pin of dc jack?
no sir. center pin goes to ground. i did swap where it was wired to the battery+ and board+. still no 9v to board.
just checked the 9v jack and it was not completing the circuit from 9v battery to the board. replaced it. now i get around .5v and when i switch it back and forth it slowly goes away.

Is the metal dc jack insulated from the enclosure in any way?

Because otherwise it looks like your 9v is shorting to earth...

well, there was only a metal washer and nut for mounting. it's a Radio Shack #274-1582, panel mount, size M, coaxial power jack.

I'd suggest trying a plastic-bodied DC jack, i think the metal is definitely why the battery was getting hot and you weren't getting 9v to the board.

i just busted open the one that was defective. it's insulated internally.the battery no longer gets hot, unless i physically ground the battery to the chassis, and that was before i changed the jack wiring.

UPDATE!!! i got it working! it's definatly the input jack! i decided to try grounding the ring again, battery -,and the LED came on. i plugged everything up and she sings like she did on the test box! i new it just didn't add up, because the ring and tip make a connection when the patch cable is out and when you push it in the connection is broken! either way, the battery never grounds! now i just have to figure out what type of input jack to get so the battery will turn off when it's unplugged and i'm in business!

thanks a million, pryde! it was your comment on the hot battery that made me look at grounds again! i used a stereo jack and completed the circuit through the patch cord ground. i was afraid it might make noise, but it's quiet as a church mouse. thanks for the link, i'm gonna stock up on them!

Those are the jacks I always use. Had a batch of 25 smaller ones which, on paper were better, and now I'm stuck with them! So definitely buy the ones in that link! Steet clear of any others ;)

the 9v jack was not the problem, although i did get a bad one to start with. and i may have killed it because i had it connected wrong. it was the 1/4" input jack that was the problem. does anyone know where to get the ones that are used in the standard wiring diagram?
