I've recently moved into a 1978 3 bed detached house and it seems to have a few strange electrical issues. I won't list them all here but there's one in particular that I need to get sorted and that's the bathroom light because trying to bath a toddler by lamplight is a royal pain in the @ss, as is shaving!
The other day my gf plugged the iron into one of the kitchen sockets and as soon as she switched it on, it immediately tripped the MCB in the consumer unit. Bizarrely though, it'd tripped the one for the upstairs lights. I flicked it back on and all seemed ok until I tried the bathroom light, which no longer worked. I hoped that maybe it'd just somehow blown the bulb but there's not actually any electricity going to the switch itself.
My question is, where should I start in trying to figure out what the problem is? Should I trace the wiring from the switch and try to find out what it's connected to, or would it make more sense to start at the consumer unit? I studied electrical and electronic engineering at uni years ago but only ever went on to work in electronics since then, so I've never done any fault-finding on this sort of scale.
