I cleaned it all, fitted a new battery And replaced switch with one
that works.
The + from the battery is connected to the switch - checked with
meter; no resistance. The other pole of the switch is neither live nor
earthed as if it it isn't connected to anything, although the wire
runs towards the ignitor.
The '-' from the battery connects to earth - all the metalwork of the
hop.
Nothing is happening at the ignitor.

could it be that all four ignitors are broken?

Thanks

The other side of the switch must go live when the switch is operated - or
the switch is faulty. Try bypassing the switch
