hmmm.....just thought of something....
in a previous post, I said:
"there's almost nothing else in an old rig that's
polarity-sensitive. watch out for radios tho..."
just now started wondering about heater
fans, and wiper motors. i mostly work on
older cats and such, so i don't -have- any
heater fans! sob sob...<g>
anyway, it's possible the fan and/or wiper
might run backwards. some of those motors
have 2 external leads, so it's not a problem to
swap the one going to ground; but some of
them connect one wire internally to the motor
case....
