pullcord switch

[colwyn]

hi people,friend of mine taken down old pullcord in bathroom asked me to have a look,4black wires in connector block,4 red wires on their own and 4 earths, pullcord has com L1 and L2 any ideas on how to connect them would be much appreciated

 

[fireman22]

where were the wires before

 

[colwyn]

good question that would be to easy he had already taken all the wires out before i arrived and now all he remembers is the blacks are as they were cant remember were the reds went

 

[fireman22]

yes well, all blacks together in block untouched. then one of the reds, the one going to the light in L1 and the other three together in C. unless you can trace it in the attic its trial and error i'm afraid

 

[colwyn]

thanks for help appreciated

trial and error? heard of a multimeter?

 

[fireman22]

crafty, as it is a bathroom light i was assuming he could trace this red in the attic, from his post i'm sure he doesnt have a multimeter or know how to use it really so trail and error quicker method for him i'm sure

 

[Steve]

i was thinking, as his friend called on him, he must have SOME electrical know-how, or have something that sets him apart from his other friends, such as . . . a multimeter? maybe i was too optimistic

from his post i'm sure he doesnt have a multimeter

Shouldn't be messing with electrics then.

 

[fireman22]

ban, most of the people posting should not be messing with electrics. some posts i just look then look away and shudder

hmm i do own a multimeter but i hardly ever use it when doing electrics.

but then i'm not the kind who gets wires mixed up in the first place.

hmm i do own a multimeter but i hardly ever use it when doing electrics.

Mostly use it when cooking, perhaps? Has it got the temperature sensor accessory?

 

[plugwash]

ok so i should have said mains electrics

tbh the thing it gets used for most is checking the values of resistors (i'm getting better at spotting common codes but unless i'm trying to identify a resitor thats in circuit there is no way i'll look for a code chart or write one down from the rather obscene menmonic i know (i would post it here but it could be viewed as racist and i'd rather not get accused of that here). I'll occasionally use it to test a lead or to try and find a track break or check a chip is getting power or something like that.

could really do with getting arround to buying an ossciliscope though

When you do buy an oscilloscope, my advice is not to but one of the portable LCD ones, I brought one and I find it hard work to use.
btw, isn't it BBROYGBVGW or something???

 

[plugwash]

yes that sequence matches with the menmonic i know but i'd still have to write it down with numbers against it to actually use it by which time its easier just to use the multimeter.
