Guys, trying to get ready for repairs to my factory Rally gauge pack on my 73 to get them all working. Did some trouble shooting to the tach and found I do have voltage to both the gray, from neg. coil, and blue wires , 12vdc, to the tach. Still not working. So, have ordered the replacement printed circuit board for an upgrade when I pull the gauge pack. Now to the clock, not working. I do believe it does have voltage , but not 100% sure. Are there any kit upgrades for the clock. Would like to have anything available to repair it before I get it pulled, or an aftermarket unit if I cannot fix it. Thanks
