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 & Q-Tip

 

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 & Q-Tip
