Hope you can make sense of this. If not I will draw and scan a schematic of how it is currently wired.
Tanks, Mike Stout
Mike – yes, drawing please. Easier for you to trace, I think.
You replaced PS1? Those were the only wires disconnected?, Doug.
Hmm. Is there a label on the alt? Is it a Furnas or Hubbell 47AB10xx or? Where does the power source connect? Is there not another wire at control#2?
ps#2 pic and drawing conflict – which is correct?
Did it alternate and duplex originally, as “in a perfect world”? Maybe look here for a couple of drawings –
Sorry for all the Q’s, but we want to get this right, right?, Doug.
It is a Furnas 47AB1 0B. There are separate 220 power supplies into each control from sub panel. There is no other wire at control 2. Diagram is correct picture not. Yes it did alt and duplex originally, only quit after I changed out PS 1.
No problem with the questions it needs to be right the first time, Mike.
“There are separate 220 power supplies into each control from sub panel.” OK, but where do they connect – I presume those go to starter relays/contactors.
Where does the power for the alternator/pressure switches connect?
If all the power is connected in the control box(es) where does it first appear in the alt/ps circuit?
I’ll guess one leg must be from the #2 box, where is the other leg of power or ground? I see that alt has a 120V coil?
Will take picture of inside of control.
Anyway, this is really hard to read – any chance of getting it in color?
Is pic 2 a different view of the same panel? If there’s any notation on it, I can’t see it.
And pic 3, I presume, is representative of either control panel? Doug
