I am fixing the fencer.
The diac checks out OK. Thanks for the advice on testing guys.
The resistor values are way out, a 270 ohm is 102, the three 270K are now between 670k and over 1M ohm! They are the 6 band type, I hate them as its not obvious what value they are with my ancient eyes. All will be replaced of course.
The gate trigger cap is sound. There is a neon that flashes as the trigger voltage come up, I can hear the tick.
The triac is getting gate voltage but not triggering, its duff, ordered some.
