Hi guys, Just FYI, when it comes to clock repair, cheaper may not be better, try and get some references before leaving your clock for repair. In my 30+ years as a professional clockmaker I've seen a ton of stuff screwed up by inexperienced/sloppy repair people, especially car clocks as they were very inexpensive clock movements to begin with and were never designed to be dissassembled and serviced. I recommended ISI in my post above as I've used alot of their conversion movements in the past and had very few problems, but I'm in no way affiliated with them....... I can tell you that a quality quartz conversion in your original clock results in a MUCH better clock than an overhauled or even NOS original, It will keep much better time using almost no power so you won't have to worry about drain on the battery, and low voltage won't damage the clock. Once installed, the conversion is almost undetectable with the exception on the second hand motion. A quartz clock's second hand moves with an abrupt jump every second, the original balance wheel mechanism moves the second hand in more of a sweeping motion. I know that the vette guys can lose points in concours judging having a quartz clock, but I'm not sure at what level it becomes an issue in mustang classes, maybe one of the judges here can chime in.................
As for disconnecting the battery, I personally feel that your chances of a spontanious electrical fire in a well maintained/restored car are extremely low, but being able to move the car quickly is pretty important. ( I still do clockwork by appt. only, but I became a professional Firefighter in Phila, PA when I was paying 2100.00 a month for healthcare, we had a job about a year ago where a 66 mustang A code 4 speed convertible and a street rod burnt to the ground cause they were parked in by another, immobile car in a body shop) I'll stop rambling now,...John
PS. Disconnecting the battery may be a good idea on a rimblow car with an old switch, I've had 2 cars over the years start spontainously blowing the horn while parked cause the switch shorted
