INSTRUCTIONS
- PROFESSOR MOTOR POWER & POLARITY PILOT LIGHTS (PMTR2030)
Application
: Any Professor Motor "Silver Series" Slot Racing Controller
Installation
Installation
WITHOUT The Use of Reversing Switch
·
The LEDs are polarity sensitive as noted by the "short" and
"long" legs in the picture above
·
Use only rosin core electrical type solder
·
Solder in the dropping resistor from #3 to #8 on back side of board (front side
of the board is shown in the picture above) and snip off excess lead length
·
Install the green LED from positions #1 to #4 flush with the circuit board with
the SHORT leg down
·
Install the yellow LED from positions #2 to #5 flush with the circuit board with
the SHORT leg up
·
Solder in both LEDs from the back side of the circuit board, be VERY careful
using a low wattage iron, too much heat can damage the LEDs
·
Snip off the extra lead length and clean up any residual flux with lighter fluid

Installation WITH
Use of Reversing Switch
· It is
easiest to install the LEDs BEFORE installing the reversing switch, if the
switch is already installed the Dremel cut in the next step may need to be
accomplished with a small grinding stone or rotary "bur" because of
the limited space very near the reversing switch
· Place a
Dremel cut through the gold circle at position #7 on BOTH the front & back
sides of the circuit board to isolate the electrical input for the bottom legs
of
the LEDs
· Solder
in the dropping resistor from positions #3 to #8 on back side of board, as shown
in the picture above, and snip off excess lead length
· Install
the green LED from positions #1 to #4 flush with the circuit board with the
SHORT leg down and on the back side of the circuit board bend the short leg
installed through position #4 over to the round pad at position #6 for the
reversing switch and solder the led to that pad
· Install
the yellow LED from positions #2 to #5 flush with the circuit board with the
SHORT leg up
· Solder
in both LEDs from the back side of the circuit board, be VERY careful using a
low wattage iron, too much heat can damage the LEDs
· Snip off
the extra lead length and clean up any residual flux with lighter fluid &
