My 1957 TR3's windshield wipers are driving me crazy. When I first bought
the
car I turned on the wipers, they wiped one time and stopped. Never to move
again on their own. I sent the motor to Clock-Doc for a rebuild. I got it
back yesteday. It is painted nicely with the black crinkle paint and the
body
was bead blasted. I mounted it with a new TRF mounting kit. It looks
wonderful... only it won't move. Anyone have any ideas? >>
Have you checked to see that you actually have 12 volts at the wires? You
can purchase an inexpensive volt ohmmeter (instructions included!) at Radio
Shack that will do this task and many others. Alternatively, you can make a
simple current tester by soldering two wires onta a 12v bulb. Disconnect
wires from the wiper motor, then hook up your current sensor to one of the
hot wires ( red wire for the Volt ohm meter) and the (black) other to the
ground. Turn on your key, then turn on the wiper switch. Use a wiring
diagram as you go and check each hot wire and each switch position. If
there is no current detected at the motor connections go to the switch and
check for current on both sides of the switch as you operate the switch.
It should be safe to assume that the motor is actually OK but I would not.
Make up a couple of test leads, one red and one black with alligator clips
on each end. using 22 Ga. wire or so ( all also available at Radio Shack). I
have two sets of these one about three feet, the other about 6 feet. Conect
one end of the set up to power somewhere ( battery, solenoid, fuse block, use
your current tester to locate if you are not sure) then connect power
directly to the motor to see if it actually operates.
Hope you have some luck.
