Yep the metal dc power jacks attached to the panel are causing the issue. I temporarily removed them from the panel so it wouldn't be grounded and it works as it should.
The control-side Vcc pins are tied together but not used. I'm curious if the metal dc power jacks for my pumps that are mounted to the panel are grounded and causing the issue.
This is the schematic for the MOSFET board.
Yes, the 5V and 24V grounds are tied together. The control inputs pins are Ground, Vcc and Signal from left to right. I didn't have the ground wire connected because I read the input and output grounds are tied together. I just added a ground wire to all the inputs. Still getting the same...
I have the signal pin on each of the control inputs wired up to a digital output pin on the Mega 2560.
The 24v DC power supply is connected to the power input and each pump +/- is connected to channel output +/-. It seems relatively straight forward but I'm obviously missing something.
I've been following this thread for a while and have almost completed my build. I'm not a hardware guy at all, I'm a software guy, but thanks to this thread I'm almost to the finish line. Can't say thanks enough, the thread has been a great resource for a newcomer like myself!
I'm testing...
Thought some of ya'll would be interested, Varner's Tavern, Suburban Tap and North River Tavern are having a homebrew competition.

I think they are taking the first 20 entries.
Yeah I was planning on replacing the beer lines but can't seem to figure out how to disconnect them from the faucet hook ups since it's insulated all the way up.
I got the faucets off (Perlick's) they seem to be in good shape. I think eventually I'll clean it up, but right now more interested in getting some homebrew flowing through it
Anyone have an experience getting an old tower back into working order?
A friend of mine gave me this to me and don't have a clue where to start. It's been sitting in storage and I like to get it in working order.
It's got 4 lines going in and is insulated all the way down. I was going to...
So I put the fermenter in the beer fridge. Theory being if it's CO2 release then if I dropped the temperature of the beer then it would absorb the CO2 and the foam would go down. We'll see what happens....
I'm getting ready to keg my IPA and I went into my laundry room to check out the fermenter and it looks like fermentation has started again after 4.5 weeks. Possible?
