Has anyone experienced the ignition warning light on a Ruby failing to work? The bulb has been tested and is OK; the ignition and charging systems both work (having worked out where the wire I pulled off went) but no red light. A clue: when pulling out the dash panel (don't you just love those seven inaccessible 4BA screws) there was a short-circuit and the main fuse blew. Having persuaded all the instruments and dash lights back into life, just this one little problem remains.
Another question: on the Seven, does the ignition light bulb (2.5-volts, 0.2 Amps working through 30-Ohm resistor) provide a "trickle charge" to get the dynamo charging?
