How to's / Re: Adding lights to a circuit controlling a 997 dc motor
« Last post by John Rudd on Today at 05:01:34 AM »ok, so in Forward direction one relay is energized, in Reverse the other relay is energized....
To add a direction indication, the simplest is to add a lamp (or led with a resistor ) across the coil of each relay..terminals 85 and 86.
if you go the led route, you will need to add a series resistor of about 1k Ohm..(1000 Ohms, Brown Black Red for the colour code..) With the cathode lead connecting to the 85 pin on the relay. The resistor can go in either led lead.. but the Cathode needs to go to pin 85.
