Now the clock will keep perfect time as long as the ignition is on. Once the ignition is off I think the clock continues to run for around 4 hours before it stops. There have been various upgrades to the stereo system in the past. I am not stokum on electronics at all, so I'm wondering, does the power for the clock come directly from the battery, or do the capacitors power the clock when the ignition is off. Would they power the clock for 4 hours with no power at all. I'm thinking maybe someone in the past may have spliced wires behind the dash and the clock power is no longer continuous but should be.
