Noticed this on the other side. Manual says the one on the left is the motor field rectifier, one of the components looks cracked. Could this be the problem?
Its posible, is that the one fed via a fuse F1 on the diagram, wires 65 & 66 ? Especially as you can visually see some damage.
Might be worth removing the fuse if so, while testing the main rectifier.
To test the main welding rectifier you will need to remove the AC connections in marked by the wave symbols.
I would take Jim up on his offer to talk you through some diagnostics. He does this sort of thing every day.
