DIYPNP - Can't get WLED output to turn on radiator fan
So I wanted to use electronic boost control and realized that the only output I had available to do that was PA0 which I had been using to turn on my radiator fan. So I switched the PA0 output to the IN point for boost control and it works great. I didn't get to play with it long, though, because I noticed my CLTs were well past the allowed 207 when I pulled over to play with settings. Sure enough, no radiator fan.
I have the WLED output at the top of the board (near the DB9) connected to the IN on RELAY 1. I copied settings over from PA0 to WLED (1 and 1, coolant > 207, hysteresis 10, no additional conditions) but the fan just isn't turning on. I made sure the connection for WLED was good from the Microsquirt to the IN port on the relay. 0 ohms. All I did was move the wire. Any suggestions? |
Do you have a pullup on WLED?
|
Nope. I read somewhere on here that it wasn't used except for ignition purposes.
|
Use PA0 for fan, then PT7 for boost...
|
maybe try reducing hysteresis from 10 to 2
I have PM5 is green power on value = 1 trigger value = 1 output channel = coolant > 196 hysteresis 2 I'm still using PAO for boost, WLED for fan, ALED for VICS |
why? I like to turn them on at 200 and off again at 190.
power on value should be 0. |
Try using a much lower coolant turn on value until you get your settings dialed in. WLED can drive a relay directly; you don't need to run it through a relay circuit on the main board.

That was the problem. Works just fine driven directly by wled. Thanks for the help!
