Overcharging

My battery is located in the back on my 1966 Glassic Phaeton (31 Phaenton) with heavy duty cable going up front, would this cause my volt meter to read higher than it should?

Bad voltage regulator or it's needs adjusted...

Last year a Summit alternator (10 DN) welded my regulator points together and I had the same condition your describing... I ended up having to replace the alt and the wiring harness...

The volt meter might be inaccurate also. What is it reading? Is it the meter in the dash or a hand held unit? Either way, check the voltage with a multi-meter before you go any further. The cable will only cause a drop in voltage if it isn't big enough. No way will it cause higher voltage.

How do you know it's overcharging? What is the voltage?

I'd look up the air gap and the point gap in the manual... Every new regulator I ever bought needed adjusted.. On my 64 Bonneville, I set the voltage to 13.5 volts @1500 rpm, the points will last longer and run better..

To me it's not worth the trouble to chase this down...... much easier to convert over to an internal regulated alt, I had such an issue with my old elec system before I convert to an internal and finially I re-wired the car...... no more electrical issues!
