How do I test that the multimeter is working.
no you are getting technical.
to be honest i've never really used an analog multimeter been with a digital one that does it all itself it makes you lazy.
try it on the next setting up, its basically gining me a reading that i suspected anyway.
I so much appreciate your help but I am feeling out of my depth and really don't feel comfortable dealing with electricity. Is is your guess that the solenoid on the shower has broken? If so is it worth replacing or getting a new shower? After this I think I need to call it a day and go over the pub.
