Name's Bob, live in WI, one little one now, and the wife and I happen to have a little acreage as well. Bought a little hobby farm last year, it's old but sure feels like home. I mess around with old tractors on the place and such, fixing things, making hay, all that good stuff. Happen to have a far...

Re: Miller 300 Shopmaster Amp control trouble

Fixed the wire on my meter tonight and started checking things again, the only thing I really did was test some more with the panel switch for the remote, checking for voltage, was moving the connections around and things started working, ran some beads and my amp control on the pedal works real nic...

I need to recheck things tonight, I was getting some off readings with my meter, found a broke wire on my meter, I will try to get some pictures and do some more testing tonight.

Re: Miller 300 Shopmaster Amp control trouble

This evening I followed C back to the panel, with minimal voltage at the panel, the meter reads about a tenth of a volt on both pin 9 and pin 5. The panel switch checks out.

Re: Miller 300 Shopmaster Amp control trouble

Thanks for the help. I checked the pedal out with a meeter tonight, I have variable resistance on the two pins however I don't have any voltage on C when I check between C and D. The book says that C should have 10V DC but I don't have anything there.
