Digital Clock Stuck at 1:00

The battery was disconnected for awhile and now the clock is stuck at 1:00 and unresponsive. Other boards (E21) report this problem and suggest pulling the fuse multiple times. Sounds unscientific. Others suggest disconnecting the battery negative terminal and touching it to the positive terminal to ground out lingering charges throughout the system. Maybe. Lastly, the hazard switch has been noted on this board (and others) as a culprit. The clock is working, but it just won’t keep time (although it is correct twice per day).

Any other suggestions? I’ll post a solution so it will be in the FF knowledge base.

Solved.

I pulled the fuse in and out multiple times to no avail. I also fiddled with the hazard switch and it was working fine and did not affect the clock's situation.

I disconnected and reconnected the negative lead a few times, but the clock remained stuck and unresponsive.

I then connected the (disconnected) negative lead to the positive terminal (with the positive lead still connected) and presto, when I reconnected the negative terminal the clock had awoken form it's stupor, responded and is now keeping time.

Hi,

I came here to ask this exact question, and it's atop of the page. Awesome!
So what you're saying is to disconnect the negative lead from the battery, let it touch the positive end of the battery, reconnect the negative lead and things should be fine?
I am really bad at electronics and have no idea what this does in electrical terms, that's why I'm asking what is essentially pretty clear in your previous post.

Thank you!

This is what worked for me, yes. It would be great to have a second data point.

Verified. Worked like a charm!
