Converted 46 Ford heater to 12 volts

[dono50]

Purchased a 12 volt heater motor from NAPA part # BK6551022 for $50.
Original shaft was 1/4 inch, new motor shaft 5/16 INCH so fan hole had to be enlarged.
Rotation on original motor CCW , new motor CW but specs state the rotation is reversible. Changed the polarity and rotation now CCW.
An easy and inexpensive fix. Was planning on using the original 6volt motor on 12 volts but my motor was NG. New motor is SINGLE SPEED
