I had to buy an old mobile home from an oilfield roustabout wanting to make a 'killing' (literally). His DIY electical repairs are only a tad better than his DIY plumbing repairs. The first thing I had to learn the hard way was that the aluminum BX armored wiring 'acquired' from an oil rig requires special connectors, i.e., Cop-Alum (or just plain black electrical tape), to connect to the copper wires on the new electric water heater! Burning electircal wires have a distinctive smell, don't you know. Different issue In the same week, a breaker in this guys' 'new-to-this-trailer' breaker box that he installed popped. Good right? Vote still out. Tripped the breaker 15 minutes after I plugged a fairly new vacuum cleaner in but hadn't turned on yet. Trying to figure out the circuits ... .. 18 to 21 switches, outlets, etc. (still a mystery) on one circuit but only 4 on the circuit that I plugged the vacuum cleaner into (the microwave was not in use). Lost 2 power supplies, a harddrive and a one motherboard on a different and what I thought was my best circuit. For 3 months, I've had all the parts incluidng a circuit tester to repair an outside outlet in a box by the door but still too chicken to try without supervision.
Please, I really do need this book! I'm getting better at rebuilding my computers but Internet is sporadic, my repair book was published about the same time this trailer was built, and I think all of my friends' husbands are avoiding me.
