If I had a modercom of electronics capability, I'd have a go at whacking a multimeter on a few parts, but I have problems working out where to plug the leads into the multimeter.
Seriously, give me a chainsaw and a forest and I'll build you a house (no steel pleeease), but if it's electronic and it ain't modular (as in, I do a pretty good job of the home entertainment system
) they you can forget it!!
