Suprima victim called up - boiler sounding as if it's trying to fire up
but not lighting. Not locked out - reset button doesn't help. Later it
was working again. I'm thinking HT cable?


Is it red?

Even if the HT lead is red, the boiler should still fire up and stay
alight for the duration of the 13 sparks before the pcb ditches out. It
should then try twice more to go through its sequence.

When you say "trying to fire up", what do you
mean exactly
