97 Dutch Star DP No coach power

I recently removed my house batteries and cleaned them and my terminals.
After reinstalling I no longer have any power in the coach. The store/Use switch does not light up or appear to work when pressed. The stairs do not function. Generator will not start. The battery is fully charged.
When I start the motor home engine the stairs will work. I do not have a breaker on the positive cable line inside the battery compartment. I did find what looks like a push button manual reset in the engine compartment. Labeled 80 on top. Pushing it does not seem to change anything.
Anybody dealt with this before?

Did you take a picture of the wires to the batteries before removing to clean the terminals, so you could confirm you hooked them back up properly?

Did everything work before you removed the batteries?

Did you hook the batteries up properly?

Stairs are usually powered from the chassis (engine) battery so that’s not the issue.

The Battery Control Center light is usually powered from the coach batteries - so that it’s not light indicates something wrong in the coach battery wiring or battery charge.
And since you took the batteries out and reinstalled them - leads one to believe you didn’t get things hooked up right, or may have the battery polarity wrong.

Followup

I did not, but I searched back a ways and found pictures that I took last year. As it turns out a wire fell under the tray and I did not realized it. The picture response, was spot on and helped me find the issue.

Thanks,

The one only issue I have left is for some reason after correcting the above issue, I can't seem to get any response from the generator when I try to start it. Is there a special solenoid that might be an issue. Does the house batteries or engine batteries supply power to start the generator? Engine starts just fine.

Thanks,

Mike

Generators usually power from the house batteries.

Have you tried pressing the Emergency Start while trying to start the generator?

FWIW - all the Emergency Start button does is parallel the house and chassis batteries. The current path goes either way (although I’m not super familiar with how diesel battery setups are wired - I.e. 24 or 12 vdc).

Finally - did it work at any time before you did any type of wiring work to the coach?

Doing the above will prove if there is a true wiring or component issue or not.

I tried the boost and still did not work. All batteries are fully charged. It had been over a month since I had used generator, prior to removing all batteries and cleaning cables and terminals. So can't say for sure it was working. Any other trouble shooting guidance?

Thanks

Where are you trying to start the genset? For the local panel on the genset, or a remote panel in the coach?

If local and nothing is happening, then you need to locate the service manual for the genset and use it’s troubleshooting guide.

If trying to start remote, then try to start local. If it starts local, you’ll need to start investigating how the remote start panel is connected. Usually remote start wiring is shown in the genset’s service manual.

Does not work local or remote. I’ll look for a manual for he set.

Thanks

Problem here is - you don’t know if it worked previous to your removing the batteries. If it did, you likely still have a wiring connection issue.

I don't know how closely your 97 DSDP resembles my 99 but the power stud (red box in picture) is the firewall end of a power cable from the coach batteries to Newmar installed wiring. This stud is the point where battery power is connected to the gen set (mine is an Onan 7500) the cable is protected by a 150 amp manual reset circuit breaker mounted on the frame behind the battery box.
The circuit breaker is only visible looking up from under the coach, so if there is no power at the stud, you'll have to go under the coach, to find the circuit breaker.
