Clock

[Cormanus]

Today's update:

1. The fuse box cover is properly oriented — even if it weren't it would be hard, even for me, to be confused as the internal layout can align only one way with the diagram on the cover.
   
2. If I remove the Clock/OP fuse and turn on the ignition, the clock turns on and works. However, it does not retain its memory and has reset to 1:00 when I again turn on the ignition.
   
3. If I remove the Meter/Illumi fuse the instruments (including the clock) don't work.
   
4. The power for the unused accessory connector in the headlight bucket is fused by the Meter/Illumi fuse.
   

I've checked the connectors in the headlight bucket and they seem ok. The clock is keeping time at last check, but it has done that before and then subsequently reset, so I'll check again in the morning. If there's still a problem, I guess I'll take the instrument cover off again and check the connectors on the instrument panel.

It seems to me the clock can get power from two sources — one when the ignition is on and the instruments get power via the Meter/Illumi fuse; and the other when the ignition is off and the clock is kept powered by the Clock/OP fuse. I can't see from the wiring diagram that the Clock/OP fuse does anything other than power the clock when the ignition is off.

I've no idea how the memory of the trip meters is retained.
