Leroy, You are absolutely correct, if a Voltage Regulator has ONLY current control relay, they will charge fine NO MODIFICATIONS REQUIRED nor would a Cutout Relay require modifications. Its the Voltage Regulators that have VOLTAGE CONTROL RELAYS that must be adjusted to work properly at 8 volts. Some VR's have only current control (2 coils, cutout relay plus current control relay), others current PLUS Voltage (3 coil relays), others have a combined curent and voltage control coil (2 coils). So long as you have the correct VR or a Cutout Relay, they will charge fine. On the coil, if you increase current through them by increasing their input voltage (8 instead of 6) since I = E/R and Power = Volts x Amps, the heat they dissipate MUST INCREASE or we have violated the laws of thermodynamics and physics. However, it may well not be noticeable from looks or a hand touch as its not all that much of an increase, but it MUST AND WILL RUN WARMER if its voltage and resulting current is increased. On the points, they are a mechanical current switching device and the same laws of thermodynamics and physics still apply. With more current passing through them and being switched and the accompanying arcing, their life must be shortened somewhat since its the current and heat and arcing that eventually destroys the conductive silver coating. Its indeed true if you increased the current passing through the coil (which the points switch) you increase the coils stored energy which eventually gets discharged across the plugs gap for a HOTTER HIGHER ENERGY GOOD BLUE SPARK. If you applied 12 volts on tha 6 volt coil the spark would even grow stronger UNTIL THE POINTS BURNED UP AND/OR THE COIL OVERHEATED AND WAS RUINED !!!!! !!!! Fun discussion yall, hope this helps your understanding Thanks n God Bless John T Nordhoff in Indiana, retired Electrical Engineer
