I have just cracked open a G9200-52033 Inverter, I bought on Ebay, I got it the part numbers wrong before I managed to get a L210 + Inverter combo. So anyway I decided to open it and have a play.
It's on the bench but I cannot get it spit out any data. Looking at its innards it seems to be missing one of the Denso Se617 ICs. So not sure what signal they decided to go without.
CLK? Perhaps, So I tried pull the request line low ( What I assume to be request as I cannot get my paws on a wiring manual for this one.)
But even trying to pull down all of the pins one at a time with my can setup, I still get nothing out. It's pulling a steady 1.02A from the 12V supply, but otherwise no signs of life.
OK maybe REQ? 500kHz clock, sequentially on all the pins. nothing.
Anyone have any ideas?
Or maybe this is just a candidate for a Damien Control Board...
