Was a faulty GI bulb holder causing the short
For some reason my tspp started blowing the f27 fuse on the gi circuit. Most of the go works fine apart from 7 or 8 bulbs on the right hand side. Checked wires of bulbs out and can't see any wires shorting.
Boards look clean and caps too. Any ideas how I get to bottom of what's causing fuse to blow?
