Aux fan controller

[Sleepin6]

Anyone ever have a working SP63 aux fan controller? I bought mine used and even had the pots replaced and the fans still haven’t turned on yet. There’s power there when you ground it out at the terminal on the board but it won’t stay on by itself.

There are lots of threads with people struggling to get them to work correctly. Might just be a bum pirce

My 2nd hand unit worked fine. Tuning it was tricky as the SP63 instructions were backwards.

I took mine off though for reasons, desperately need to put it back on.

When you say backwards can you explain?

Old notes are old...


It took me forever to get the temp right, turns out the enclosed instructions for tuning the pots were wrong for off temp. Made my notes, adjusted accordingly, and it worked great for like 3 years before I removed it. Gotta throw it back on...
