I can't get the rallye gauges working in my 1970 Challenger. I have replaced the instrument regulator and condensor. I am getting 12 volts to the regulator. I have tried to ground rear of panel with a jumper wire. The alternator gauge and tach work but not the fuel, oil pressure or temp gauges don't. I don't know what else to try.

There are only two things in common with the malfunctioning gauges: Ground and the 5 volt regulator. Check the octopus that comes off of the regulator for 5 volts. Use the ground that you have jumpered. If the 5 volts is there, bad news. As mentioned previously, a shorted regulator will pass 12 volts to the gauges and will fry all of the ones it feeds. It does not take much time for this to happen.
Good luck,
