After two months in maintenance JT has arrived back at its spiritual home with a mystery battery charging problem. Her new battery is excellent, but the low voltage light refuses to extinguish, while the ammeter proves to be very lethargic indeed, to the extent of not showing any charge at all.

Amongst the suspected culprits is the ancient voltage regulator, the antiquated generator or worse still, horror of horrors, a hidden earthing problem lurking somehwere in the midden of tangled wires that lies behind the instrument panel.

The most likely of these is the voltage regulator and we have a couple of potential spares robbed from an another old aeroplane, but the problem with old aeroplanes is that they are made up of parts that nobody makes anymore and more to the point, know that much about. Will these be compatible with JTs museum exhibit electrical system? Who knows.

Yep, the problem with old aeroplanes is that while they delight the pilot with their nostalgia and charm, every now and again they throw a problem at you out of the past and their nostalgic and charming parts suddenly become the bain of your life!
