Today, I found that PO has disconnected the dash battery boost switch from the boost solenoid. I tested the solenoid and seems to works fine. Can anyone think of a reason why the dash boost switch would be disconnected? Or any reason why i shouldn't hook it up again?
Cheers, Wayne

I'd check cables very carefully. There are over 25 feet of places where a circuit could be very short.

Wayne says he has a "1973 Glacier 260". If stock, it doesn't have the 25 foot cable to the rear.
BUT... 1973's and 1974's are more likely than others to have battery systems changed from stock.
For example: If a PO wanted to put a large house bank in the rear he may have moved the house battery to the rear (leaving only the engine battery up front) but not installed the large gauge wire and assorted equipment to make the boost work. (That large gauge wire isn't cheap!)
I have seen exactly this, (on a 1974 Glacier 260) but they left an effectively disconnected, dead battery up front. ... Just an easter egg for the next owner to puzzle over.
I agree to really check out the system BEFORE reconnecting the boost switch. --- Could it be that someone was working on the dash and accidentally left it unhooked?

Thanks Everyone
The setup seems almost stock - I have two 6v house batteries up front, along with the engine battery.
The Solenoid side terminals are well utilized with several wires connected on each side - and I notice that there is an isolator in place nearby.
The one of the smaller terminals on the solenoid goes to chassis ground and the other is bare. There doesn’t seem to be any wire nearby that was disconnected from the boost switch, so i was going to either run a new wire or trace the original wires.
As i recall, the PO used a short heavy wire with clips to jumper across the solenoid when charging. I have used the same wire for charging the engine batter when on shore power and when the engine battery ran dead in the summer - I used it to connect the house batteries to start the engine.
Just as another data point that may, somehow, be connected: The PD9140A charger/converter died recently so i replaced it. The system seems to be working normal and the charge-wizard is behaving predictably.
Thanks for all advice
