OK, here's a question for all the old AWA techs on here!!
Looking for some info/schematics for a power supply 1LP82162, made for AWA by Antaron Aust. 13.8VDC 8A supply, from old commercial 2-way site.
Also some info on the AWA "Automatic Battery Changeover Unit" 1LW82185. This little box has 6 wires exiting - Blue, Red, Orange, Black - then Red & Black, connected on the PCB to points A, B, C, D, E and F respectively. So, I gather from the simple cct and testing that Blue (A) is power supply/mains
+, Red (B) is output (to radio) +, Black (D) is negative, and (E) Black, (F) Red is the battery - and +. So, my question is - what is the Orange (C) wire for? It seems that power applied to (A) also appears at (F) as a charge voltage? But is (C) also a battery charge???
I'm hoping one of you knowledgeable ex-AWA techie types in here will have seen these old things around and can give me some helpful insight as to correct connections. The PS seems to have 2 outputs, but are they the same output or separate??
Don't feel like fully dismantling these if I can avoid it!!!
TIA
