Wow! Someone willing to work for free and no takers? I know there's an economic downturn etc but free labour has to be worth a chance, or has insurance and PC got too expensive? If it doesn't work out then you can always say goodbye. With all due respect KDG, I'm sure you weren't born an...

Hi HYP I see you've posted this on the sparks forum too and as you can see there is a lot of discussion and disagreement, this is because 6mm is marginal at best and depends on many factors, some of which are listed directly from BS7671 by Goldberg above. However there is no substitute for an...

HI HYP I can't advise on the shower but first check what size of cable and trip/fuse you have. A lot of the earlier electric showers, (possibly before you had the 8.5kW) were lower wattage and have smaller cables/trips. Might be worth having an electrician mate check it for you. Probably...

Hi Coleaine I don't claim to be an expert at this but please have a look at a thread of mine "Burner problem", currently on page 5, similar problem to yours, if you are not certain about the solenoid opening try a photocell for about £6. Mine was breaking down and not allowing the coil to...

Thanks for all the advice Martin, much appreciated. I'll call someone in and get it set up. Cheers

I know the components need to be disconnected Tony, that's why I made reference to my initial test results, then I just wanted to prove that the cell was light responsive, or not. Tonights test was only on the two photocells, unplugged and I even held them in the same place to try and get a...

Ha, you think like me! I wondered the same thing, unfortunately nothing clear cut. The original photocell is about 50-60K in garage light and is just about making infinity when covered, the new one (MZ770s), is around 40-50K in garage light and easily makes infinity when covered. When I was...

Martineire/Agile Photocell did the trick, the boiler fired up first time. I should have done the laymans thing and just stuck a new one in at the start but I like to know why things don't work and then pickle my own head! I can only guess that the cell was breaking down or resistance has...

Thanks Agile The photocell cable belled out OK, I've bought a new potocell to try tonight, I'll let you know, if not I'll try the resistor trick. Is the controller looking for a fairly specific resistance? As you say it seems about right and is changing resistance with light but perhaps it...

Thanks to both. The electrodes are sparking and the solenoid does open with 230V, (new pump and solenoid). This is what I changed originally when I had no oil to the burner. At that time I checked for voltage at the coil and had 230V and checked the coil resistance, about 2.2K ohm from memory...

Hi folks, I'm new here and would like some help please, I'm not a boiler guy I'm a M+E eng. and have always serviced and repaired my own boilers and those of my family etc. I'm not getting voltage to the oil pump solenoid on my Sterling burner. I've tried a spare, (new) Satronics TF 830 with...
