I've fixed over a half dozen Borg clocks and they are a cinch to get working. Only real down side is if the magnectic coil is fried and I haven' found one yet. With a small screw driver, remove the back screws and holding the Time set shaft with a pair of needle nose, screw off the set knob. Open the clock and look at the points which I almost guarantee you will need cleaning with a point file ot crocus cloth. Then pull back the movable point to wind the spring. As it winds down , clean everything in sight with an alcohol swab and then lube with a thin oil (watch oil from local clock guy is best but I have used silicon and its OK). Keep winding the clock manually until it continues to run. Then apply six or twelve volts and let it run overnight on the bench. I always put a one amp fuze in the test circuit. Good Luck --'s fun and easy. ,,,Dick Curtis You can use a 6 volt clock, in a 12 volt car, if you add a sufficient value, voltage dropping resistor, in the power feed.
