Hello.
I have a Pyronix Sterling 10 installed which was working fine until I switched the mains power off to reposition the fused spur feeding it. The power has been off several times for various DIY needs as the house is in need of general upgrade and I've never had a problem before. The beeper sounded indicating that power had been lost and it seemed quite happy to run on battery for a few hours, until the battery drained down. Fine I thought, it will be o.k when power is back on, but the whole thing appears utterly dead. I have changed all the fuses assuming there had been a surge on power restoration, starting at the 3 Amp Fused spur and all fuses on board, including the one that supplies the transformer in the mains connection block. Still Dead. I then presumed that I had blown the circuit somewhere, so have now gone to the expense of buying a new board. Have changed that out fully and still nothing. I am pretty sure that mains power is getting onto the board as I can see the meter flicker when I test, but I only have a rudimentary voltage tester for checking mains voltages.
On another forum thread I note that someone seemed to suggest that the battery needs to be connected first, but in their case it made no difference to the problem they were experiencing. I am wondering if like a car, if the battery is dead (the original installation must be about 10 years old) and not recharging, it is taking the whole system down. Does anyone have any thoughts or ideas what to do next?
