I'm off work this week, so I've been pottering around doing things and wasting time playing Warcraft and suchlike.
This afternoon, we went to the airfield and installed a new battery on to the plane. We took it up for a while, and everything was fine for the first half an hour or so, but later on the electrics started playing up again. We had a few people tell us the radio sucks when we were back in the circuit, and after we'd landed I managed to get the whole panel to go dark by wiggling the wires around. That's not good. As the fuel pump and strobes still work, I'm suspecting the switch.
