Hey guys, I need your help please. Any idea why is my DC system showing 0V for both battery bank - PORT and STBD? All of the batteries are brand new and all of the switches and brakers are ON. Actually I can turn ON bilge blower, nothing else. I don't know what I am doing wrong. Boat is Sedan Bridge 360, year 2007 and I am a new owner (boat was sitting for a couple months). Thank you so much!

Are your battery charger switches on (main distribution panel)?

And are your main battery switches on?
 
Yes, battery charger is ON and charging, also battery switch is ON. If I am trying to turn ON port or stbd on the DP I can hear click from relay, but nothing happened. What is weird all of the bilge pumps and bilge blower are working (they are green on the DP), but nothing else from DC (no lights, no stereo). Maybe electronic addressable module or bad ground? Thank you.

Bilge pumps are powered before the switch 24x7 power
So if they run likely batteries are ok

the red lever on each is a manual override
Turn them on Locked symbol
If you get power the realy or control issue
 
Do you have a NEMA box where the main relays are? Need a picture of your main switch panel where you turn on your batteries. In the main box where the DC relays are located there are fuses (mine are 7.5 amp slow blow ATC). If my main battery on off switches are not working that is where you go, probably blown fuses that control the relay.
 
So you system is completely different with EDS. I looked up your diagrams and you have 2 100 amp breakers that feed power to your EDS controller. You need to verify you have 12v on the controller side of those.

I can't tell exactly but I think your breakers are off that feed these, check and reset the yellow levers and let us know.

I checked all of the fuses and they are looks good. I think the breakers are showing label (I) like ON and (O) like OFF, not sure, I will check that. I think one of those bigger battery switches (with red lever) is not correctly working, I am not able to turn it ON or OFF like the others. I have to check that with multimeter. Thank you.

Yep the key is to read 12 volts in and out of those 100 amp breakers.
 
OK, I checked every single breaker and switch again. I have 13.5V on the 100A breaker, but weird think is, also when the breaker is on off position. Same think with those bigger battery switches, always measuring 13.5V no matter what, on or off position. I think one of them is bad (first one on the picture). Also the electric modules looks bad..thank you guys for helping

Yea, a couple of those modules don't look good. Did you suffer from a high water situation in the bildge?
 
I had termites everywhere, but there are finally gone after tenting. No water. I probably gonna start replacing one thing by other..thank you
 
What do you think, how can I test those 3 gang battery switches (the big ones)? I have voltage on the output cable, but not sure, if they are working..

You can test everything with a volt meter.
 
Looks like a module 366hmm sr is bad and makes issue with DP. Do you guys know about some to buy? Thank you.
