Please help and tell me what each of these are. I have power to the fuel solenoid but its jot working. Will not fore unless i use starter fluid then it stalls out some time later. I have replaced all the normal culprits already. The top right solenoid is hot to the touch.

Your fuel shutoff solenoid has two hot wires . One is hot when starting only and the other is hot to keep it open while running . The solenoid itself could be weak, even some new ones .

Have you tried using a zipp tie to hold the fuel shutoff all the way open ?

In your picture , one solenoid is likely a starter solenoid and one is a battery combiner solenoid or house power disconnect. There might be another starter solenoid on the frame underneath , mine has one on the a frame rail .
You also have a relay in the picture , could be the exhaust brake if you have one .
In the picture the flat one with the arm on it is a breaker .

Harold your comments are spot on.

I would suspect the solenoid. Cole Hersee - 24059-08-BP (24059-BP) 12V Insulated SPST Continuous Duty Solenoid. I have not seen one that old in 10 years. I carry 2 as spares. I have had multiple fail. On my 94 Aristocrat I had multiple fail. Don’t buy the knock offs.

On my 97 Monarch 8.3 I have one in the front electrical compartment, one on the frame rail below the motor and one in the rear electrical panel box. I’ve had them seem fine until load applied and fail. Of course there is power when you check because you are not putting the load.

If that big shut off is still functional that would surprise me also. That is original. I put in a mechanical Perko to replace long ago. I relocated to a bay along with my batteries and inverter charger.

No two Barths are the same. I sometimes think they had a plan to never do anything the same. We had 5 Monarchs together at a GTG in Minnesnowta. We went from one to the next and electrical was so different it was scary. 4 had 2 electrical panels. One only had one we could find but also there were electrical items we never found.
