Hi Guys!
I have a problem with the activation of the relay to control the fan of my car.
I'm using js11(pa0) with the output circuit
Relay pin:
87 - Positive Fan
30 - Positive Battery
86 - Megasquirt 2
85 - Positive Switch
But fan is always on

That would explain it (always on, that is), alright!9alex16v wrote:Relay pin:

You need to decide if you are switching the positive or ground to the fan motor. That circuit shows the ground switched.
Personally, I don't like that circuit. I'd have a separate 12v with fuse for the high current fan motor. The 12v for the relay coil is low curent, and could come from the MS 12v side.

Re: MS2 v3.0 Relay Control JS11(PA0)
You configure the output status by setting the "power on value" and the "active value".
Correctly identify your MS ecu here
