So I'm taking the plunge today. I plugged in my control panel and hope to have my brewery operational this weekend.

So far pretty good but I've hit my first issue. The Amp and Volt meters aren't lighting yep (everything else appears to be working).

A few details.
I have a DIY 30A kit from Kal.
I did turn the adjust the DC power all the way down per directions as I didn't realize Kal's are pre-set (oops!)
The meters were unplugged when I plugged the panel in. I adjusted the DC to 5 before plugging in the meters
The meters have never lit up at all

Upon additional testing I found that the plugs going into the meters read 5 when unplugged so I assume that's wired correctly
However when the meters are plugged in I see the DC drops to about 1.5.

Any ideas or additional questions? I may have already fried them without knowing but thought I'd ask.

Thanks

Hi!

Take a look at our troubleshooting tips here: http://www.theelectricbrewery.com/forum/viewtopic.php?t=25460
Specifically the "Volt and amp meters" section. It'll walk you through everything, step by step.

Good luck!

Thanks Kal. Always fast with the help. I have the post printed out already but did read it another time. Didn't resolve anything for me. Will be a bummer if I just fried them but given that they never flashed on at all and I actually had them unplugged at the start before confirm ~5 DC. And even then I plugged one in at a time.

Does that fact that the reading drop from 5 to about 1.5 when the meter is plugged in mean anything?

If the voltage out of the power supplies drops greatly when itís hooked up to a load (a meter) the power supply is either defective or itís trying to keep up with what the load wants (and not able to) which could mean the load is defective. Miswiring issues can result in both the power supply and load being damaged. If you have any other 5v dc power supply you can test the meters to see. Good luck!

I should add too: Make sure to use the nylon standoffs/screws/nuts we include to mount the power supplies and not a metal screw as otherwise you may short the metal screw against the backplate. That could also cause issues (though usually it just destroys the power supply).
