30 year old Potterton Neatahet MK2. Having problems with ignition of the pilot light, the boiler fan etc will run but the pilot light will not light, have changed the Ignition monitor for a old one that I had in stock,, this worked for a couple of ignition cycles then stopped working. Checked original Plessey Unit (which has earth) and there seemed to be dry joint on the circuit board, resoldered and worked OK for a couple of hours and several start cycles now stopped working again. I notice that the spark generator neon is flickering. Has anyone a clue what might be the problem. If not able to resolve would like any information on a boiler that may be a direct replacement.
Thanks in advance for any info.
