A good few years ago I had a similer problem with an old Patterson timer, Many will possibibly hold their hands up in horror, but I gave and the a good clean and spray in Rocket WD 40, it was over a bank holiday and the shops were shut, and I always have WD in my old car, cleaned it and it worked fine, ifnyou do go that route spray carefully and do not apply to much, and leave it a while to dry

Personally, I'd stick with the contact cleaner, IF you are going to do anything at all, as it leaves no residue, unlike WD40. Also as said, timers on ebay are listed constantly at some very good prices.
As a side note, I love my cans of WD40, I use it for so many things but NOT on electrical switches etc. In fact check out the actual WD40 website, where it lists HUNDREDS of uses for it, but none like your problem. BUT, they do have a specialised item that they do recommend (but of course they do! ) = 'WD40 electrical contact spray.': http://www.wd40.com/uses-tips/constr...s#video-player If still unsure, check out the first comment on the following link, which was written by someone who really sounds like they know what they are talking about!! http://www.goldwingfacts.com/forums/...nnections.html Terry S |

Personally, I would be inclined to look out for a good used one, they seem to be as chips these days, and would probably be more reliable than the one you have, most these days have a LED or LCD read out of the times set, and are a lot easier to use in the dark than the one you have, which looks to be a very old type. why not look at Second hand darkroom supplies, they usually have a good range at good prices and are Forum sponsors

Timer
Can I ask what make it is please. To me it looks like a RAYCO model but I have never seen one where the switches were one above the other like yours. I had one where the switches were side by side.
If it is a RAYCO they are/were exceptiojnally good products, so I would try to get the one you have working properly - it will outlast you! Probably the timings discrepancy is down to lack of use. Once cleaned, (it doesn't need lubricating)it should be as good as ever. |

It looks like Polysales (I think), or DeVere. I have a Rayco which has the dials horizontally and a toggle switch for power

DON'T use WD-40, it leaves a deposit which will only make matters worse. You may find that turning each switch back and forth over the whole range several times will clean the contacts enough to get it working.

In addition to the above (except the WD40 - as others already mentioned, don't try that) check that all the resistors on the switches are making good contact and are not shorting to adjacent ones - tho it does look OK from the photos. Likewise, check the wiring is all well connected (give it a little tug) and is not shorting against the next one along.
Not too keen on the way the indicator lamp is wired up - you can see bare conductor that will be a few mm from the metal case (unless it's a lot deeper than it looks in the pictures). If there is no earth wire going to the case either chuck it in the bin or add one. And then run it from a RCD adaptor - the whole thing looks very how-you-doing to me.

This timer uses a combination of resistance (selected by the switches) and a capacitor to set the on time. It's quite old, so it's likely that the timing capacitor is not as good as it used to be.
Do you know anyone handy with a soldering iron who could replace it for you? However, try the switch cleaner first. See if you can buy Servisol contact cleaner. Steve. |

I have ordered some Servisol cleaner - should be here either tomorrow or after the weekend (depends on the weather and if the boat runs). I'm the kind of person who with a bit of knowledge is not afraid to dive in - I can borrow a soldering iron or get one - my way of learning needs to be hands on with some written and directed input also. Point out to me what is what and I can research and move forward with my skill set. Switches and resistors I recognise (there is no indicator lamp), there is a fuse case... Capacitor I guess/assume is the orange coloured cylindrical part on the PCB..? Last edited by longhouselife; 10th January 2019 at 07:33 PM. |
