I have a 72 Charger that is in overall good condition that is finally back on the road again after 27 year break. The previous owner had plans to make it into a Super Bee clone. He had pulled the engine and really didn't get much more done before I bought the car a year ago. A complete rebuild on the engine to what I hope is closer to the 71 power out put. On the first start and since several hours run time in the shop and maybe a combined 10 miles on the road the factory tack is reading high 400 to 500 at idle and its seems more so as you throttle up. From what I have read in the factory service manual the early 72's had a voltage limiter coming in to the instrument panel. I haven't started digging into this yet but am about to. The other gauges are working correctly. The tach actually moves up some when you place the car in gear, seems to hold at 1100 on the car when checked with a DVM on RPM setting it looks like 750 as it sounds to be about that to me also. I plan on checking the tach electrical connections but other than that I am looking for suggestions. I have thought about running a slaved in wire from the coil to see if that makes any difference but I suspect it should be ran to the voltage limiter. Is there any adjustment on the tach itself? Any help is appreciated.
