Hmm I have an issue.
I followed the pin outs M1 to M1 and gate to gate. soldered them on and tested and same issue with the GI. I left the old "earth " wires on a ring connector bolted to the old triac. Should these be soldered to leg 2? Should I run a new wire and ring connector to the old triac and then solder the wire to pin 2?
Thanks
Clive
