I installed a new battery to replace the weak battery in the 300DT. Took a reading today and it is charging at 13.9 volts with no loads (at the battery) at 2000 RPM. If I turn on the headlights and blower, it drops to 13.6 volts at 2000 RPM. I may still do the diode mod and add a switch to short it out so I can select high or normal charge.
