I need some help, before I dig into the circuit board

inside the EVI Power Pack that I wired to 240V AC

but got no response, even after pushing the test button

to simulate an EV had connected to the AVCON pilot signal.

 

I checked that the unit received the proper 120+120V

(because the internal transformer to power the logic board 

is wired to receive 120V, which is odd since it has two 120V 

windings that are in parallel, instead of putting them in series 

for 240V, but oh well.

I checked the output from its internal power supply and

saw that the transformer delivers about +/- 16V AC that

gets rectified and regulated by a simple LDO to 12V,

so it appears that the circuit receives power, but the

many chips on the board I did not check yet,

hoping to find someone who either has a schematic

or who has experience trouble-shooting those old units.
