nasty shock

[Billy Bob Bob]

had a nasty electric shock to day,was faulting a potterton puma as some of you know when faulting you do it under live conditions,anyway what happened was this no power on lights to boiler so after checking fuse and supply cable i had todrop down the main pcb houseing[done this with power off]turned on and went to put my meter on the wireing strip and wham i pulled away quickly droping my meter.what had happened is the ignition bored had been replaced by some prat who had re-fitted it with just one of the 4 plastic locateing pegs,as soon as i dropped the houseing the bored moved making the caseing live obviously what i done is touched the boiler some where inadvertently.you cant see this bored on this boiler because its got a steel plate over it and mains in connections are behind it,goes to show you dont know what somebody has done before you d i yers you have been warned!!!!!!!!!!!!!!

Hope you are Ok gas man
You are right though ,we all should know better but we all test to many things live,we do not need to most of the time but we never learn,I even still use a neon tester while leaning on my multi meter for just a quick check,no quicker really
I have not had a shock for quite a while,last one was from a double live into system,isolated,never checked correctly,rush,rush,rush
With regard the puma ,was in dry joints on main neutral on board

Went to a puma today,board damage,resoldered,fan gone,pressure release valve leaking,customer said heating sometimes not coming on,so divertor wax capsule on its wasy out,pressure gauge leaking,casing all loose but apart from that all ok but it will be humming tomorrow after I have finished with it......hopefully....maybe for a week anyway
New boiler I hear you say....Landlord job I reply

Gas Man,
If the ignition board made contact with the outer casing of the appliance then assuming it was the 230V input side then somewhere the fuse/MCB should have tripped as the the appliance should be earthed. If it isn't then it needs rectifying as the casing could become live again under fault condition and do someone more damage.
Glad ur OK though
