Hi Ron,as you know I recently converted my PV 6v to 12. I am finding that the wiper DR gets VERY hot and was thinking that I should spread the load. Looking at the write up I note that the blower motor DRs would be wired in parallel but the wiper should be wired in series.Can you please explain why that should be so?

Heater blower motor. DR = [0.6Ω 150W, (3 2Ω resistors in parallel). Bill reports a 90 degree F rise above ambient after 15 minutes of operation.
