Howdy yall. As the title suggests, I have a MEP806b here that has 24 volts coming from the battery to the slave. But no power or lights or anything to the control panel or anything behind it in the box. The manuals I have seem to be extremely lacking in this department. Any help would be greatly appreciated as we need this generator up and running asap. TIA

Is this set new to you? Have you ever seen it run right? What manuals? Did you down load them from the SS forum? What have you checked? Did you look at S17, the emergency off switch? Do you have 24 VDC to one side? If pulled out, to the other side? Is the set complete? Parts missing? We need a little more info.
So quick update. This set is not new to me. I had it running before it and I got moved to a new location. The set is complete. I just got back in from tinkering around a bit more. I swapped out the batteries just to make sure they are charged and good to go. I definitely have 24v to the slave receptacle. But now when I hook up these batteries and then try to press cb1 in, it will trip. And of course if I try to hook them up with cb1 in, it'll try to melt the cable and terminal. So I think the problem lies somewhere between cb1 and the batteries. The ground is well grounded. All cables are tight and the same goes for the bolts on the slave receptacle. TIA

CB1 is the circuit breaker for the alternator G2
In the main electrical wiring diagram CB1 is referred to as F2
This indicates a problem with the alternator

And under normal circumstances, all the wiring diagrams are printed on metal plaques and installed on the inside of the side doors of the generator.

We have two wiring diagrams available in this Forum's TM section for the 805B 806B
There is a discrepancy as to the labeling of CB1 / F2 and how TB P6-c actually connects, either before or after CB1 / F2
The colored Drawing from MCII shows connection to TB P6-c after CB1
The published TM wiring diagram shows connection to TB P6-c before F2 (directly from Battery +24V)
Note: The plaque wiring diagram(s) inside the side doors overrule any and all published TM's or any other Wiring Diagram
