Hey guys,

Finally have my old v4.0 board and zero W combo working. Boots up, connects to wifi, reads probes, all good. No love for the blower though, and only see 0.15v or so on the blower output with blower at 100%. I'd like to do a voltage check on the board but I can't find the old v4.0 voltage check diagram. Anybody have a link or picture of one to share?

Also suggestions on what to check first on v4.0 board with my low blower voltage symptoms are appreciated as well.

Cheers,

Tim
 
So turns out I found the diagram in an old post I made many years ago!

I will check these few points here in a bit. Any advice on other troubleshooting to do for this old v4.0 girl is appreciated.

Cheers,
