Hi there.
I have a serious problem I can't seems to fix.
When we where out playing a gig last weekend the bass player almost got electrocute when he touched the bass and a radiator simultaneous.
Not good not good.
We do not run our PA-rack with a grounding connection because a lot of our gigs doesn't have a plug with it in. Most of the time we play in small village halls build before World War 1.
I powered up the rack in my storage hall and measure 120VAC with my voltmeter between an radiator and our rack. I have unpluged all machines and tried to eliminate the source but every unit seems to add some voltage to ground. Some of the units has 44VAC between rack and ground and some units have 120VAC.. I have tried to pull all the units out of the rack but nothing helps. When I puts one unit back the 120VAC is showing again.
What am I doing wrong?
Cheers
Søren
