This is for a Hyperball... Been trouble shooting a issue where the cannon coil is blowing F2 4amp fuse... So in trying to troubleshoot that mess, I started to check the voltages on the power switching board. To cut to the chase... They do not seem to be right... The trans is a Williams 5610-09806-00 and the voltages i think I should be seeing are on the image below of the power switching board... Below that image I added the transformer and how the voltages look there. Input voltages are driven from the AC into the cab thru a filter but look good before hitting the transformer.

Also included the pictures where I moved the lines from terminal 3 to 2 and from 7 to 6 to up the voltage (did, but minimally)

Could assume it is the transformer (I did) and I had an extra that I wired in its place to get the same low voltages. I am lost here. Any help for suggestions at this point are welcome!

How are you measuring? I know this sounds stupid, but I want to ask. So many people don't measure voltage correctly. Also, check your grounds, and make sure they're all contiguous.

Totally legit question considering it's me. I have the ground going off the ground cable that comes up to the head. For the voltages I checked on the power switching board. The voltages I pulled off the Transformer I was running my ground to the side of the Transformer itself. But also tested to the negative / neutral lugs of the Transformer

Can close this thread... was being.... slow.... figure out I was measuring the wrong points.. sorry guys... all is well on the voltage. Now back to the display issue and blowing f2 in the other thread...

When measuring AC, you can't neccesarily measure from ground. You need to measure on each branch of the AC circuit. For example, in the first picture, you would put one lead on transformer terminal 11 and the other lead on terminal 12 to see if that winding is working. In the second picture, one lead goes on pin 1 and the other on pin 2 to verify 125v AC switched is working.
