Well, we tested the motor today in both directions. With the field connections reversed (compared to “stock”), the motor turns much more slowly: 1480 RPM @ 12 volts, vs. 2275 RPM.


I’ve just posted a question to the EV list. 800 RPM seems to me like a huge difference to be fixed with a brush timing adjustment alone. Then again, what do I know? I’ve already demonstrated I’m no expert!


Will post back when I’ve learned more.
