Clocked fixed but strange

[Blockpower]

I've just fixed my 1980 clock. It was a little odd to be honest. After stripping lubing cleaning contacts etc applying power to it did nothing.

I had an earth on the plate, 12v at the positive. I traced the 12v feed to the coil and to the contracts. Contacts closed showed a12v circuit passed on the switched side when closed but the clock didn't energise.

So I put it back in the car thinking I'll get a new one sorted.

To my amazement the clock worked and continued to work. How very strange.

I can't think why having had a positive feed on the contacts so the earth was obviously good.

Anyway happy days..

A classic case of switch it off and back on again lol gotta love old cars.

That's happened to me many times, something doesn't work, I strip it down and find nothing wrong, put it back together and it works!

The real `Master Class` is when you put a component back together , have a bit left over and it still works
