this all looks a bit iffy, relay J2 and the three fuses or resistors below it, unless its just muck. poss short on the transistor close by?
That is good. It means we have AC mains, there's no blown fuse, the auxiliary transformer primary is OK, and the secondary output voltages are correct. ( I don't know why it needs all those outputs, most auxiliary power supplies are a straight single 24v.... )On checking the wires you described there is 26v , 18.6v , 18.6v , 26v.
The Tec-Arc photo is of the older type of pcb, with 'thru-board' components, not smd. See what they say.
A replacement from Sealey is £82 plus vat, so it's not that much more.
