I have an ancient Ideal boiler as part of an equally ancient system. Last week the mains fuse blew and after replacing it I found that the controller was dead. I've done various things such as changing thebattery in the controller, which confuses me a bit as it's a rechargeable battery with no way to recharge it. I assumed it trickle charged when in place. Anyway, still no go. I've tried two different new controllers to no effect. It seems that there is no power going to the control box but beyond replacing the mains fuse I don't know where else to go. The wiring on the plate looks ok. I'm pretty ignorant when it comes to central heating and any advice will be much appreciated.
Thanks in advance,
Jim
