Stepper motor wiring


Recommended Posts

I have an RV8 in my TR7 and I am installing Megasquirt 2.  One of the jobs is to connect the stepper motor but I need to know the function of each wire. So far I have this information:

Green/white. Pin 1
Red/ green. Pin 26
Orange Pin 28
Blue grey Pin 29

Does anyone know the functions covered by these pins or where I can find out?

Cheers

Connect MS to the stim and set the stepper fully open 256 steps at 20 degree engine temp and fully closed at 90 degree engine temp

with the laptop.

If you like make a gauge with the steps from 0 to 256 and a water temp gauge if not already on the dash.

 

Now you can play with the wires changing water temp at the stim an find the proper connections. It was quite easy when I did so some years ago
