Fan Control easy question

Post by cheap_sticker05 »

Okay, hopefully someone can answer this quickly. I bought the board mod from DIY to controll a fan relay, My question is does this mod switch the coil GROUND on the relay, or does it send power to the coil on the relay? I am just guessing and have looked at a few diagrams and it seems like it could only switch the ground.
thanks,
Rich-

It switches ground, your interpretation is correct.
