    How many amps should my veglia clock be pulling on my 1979 308? My battery has been running down after a few days, and it certainly didn’t use to do this. I had some other “anomalies” I was able to fix with the current draw, but after painstakingly going through the fuse block and double checking through the battery cable in series, my clock is the only thing still pulling current with the door closed and ignition off. It is pulling between 1.2-1.6 amps, which seems excessive. It was repaired bout 2 years ago with new internals from Palo Alto Speedo. I am wondering if somehow the radio suppression capacitor, which is on the same circuit, could be the culprit. Any thoughts?

    thanks in advance.

    Are there only two things on the one fuse? On 1985 cars, the clock, cigarette lighter, emergency lamp socket (I think) and horn are on the same fuse.

    Lots on the fuse but was able to trace down to one wire. Onlybthings Only things on that circuit are the clock, emergency light socket, and supposedly the radio noise suppressor (capacitor) which I have no idea where it’s at. But when I unplug the clock, the amps drop to zero with the circuit wire continuing to the emergency socket, if that makes sense.

    Not quite sure what you mean. Does the power wire go to the clock connector and there are two wires on the same pin? e.g.

    i.e. if you disconnect the clock connector, the noise suppressor is still in the power circuit, but the clock isn't?

    Wire comes in from the harness to the clock. That terminal has two wires and then continues in parallel to the socket. Terminal on socket has two wires, which then continues in parallel, to what I assume is the suppressor. The first load on the wire is the clock, but either way when you pull the connector off the clock, the circuit is still complete to the next loads, because they are in parallel.

    I think you're going to have to draw a diagram for us. If you don't have a graphics program, just draw it on a piece of paper and photograph it. Then post the photograph.

    If everything is in parallel, it does sound like a clock issue, but we need to be sure.

    Thanks… so when you disconnected the clock, the power wire is still connected to the power socket, etc?

    This definitely means the clock has broken (again)

    Well the clock is working, just pulling 1.5 amps

    Not sure what do with that. Last time I had it fixed it was $800 for the new mechanism, which took 6 months to source

    As I recall, Fiat Spiders from that era also used a Veglia clock. Used Fiat units are cheap as chips and handy on such places as eBay.

    Buy one, gut it for the motor, and swap the 308's hands and/or face plate if they should not happen to already match.
