Ecumaster forum

I am trying to hook up a fan to a relay through one of the Aux output. I can set it up in the ECU and see it function on the lower status bar but there is no voltage coming out of the ecu lead that I set up. Tried all of the the available outputs to no avail. Any thoughts would be greatly appreciated.

Thats because you havn't read the manual.....

Yes, when everything else fails, it is time to read the manual

(AUX outputs switch to ground.)
