Proteus: Help! I might have fried something
Posted: Mon Apr 10, 2023 3:23 pm
I might have done something wrong, I hope it's repairable.
I first pinned my ETB and cam/crank sensors on my proteus (v0.5 january 2021 in case it helps), everything was working.
I then pinned the injectors and coils (gen 4 ls based engine)
Everything was still working.
I then tried to wire my CEL, I wasn't sure if it needed a negative or positive wire so I started with a lowside pin which didn't work.
I then tried and ign wire. CEL light was working but I little too dim so I used and high side which didn't work soo I wen't back to the ign wire (ign 11 I think) since it was better than nothing.
So after that, I was ready to find TDC and set the TDC degree.
That's when everything went south.
ETB stopped working (at first, I thought it needed only to reconfigure the TPS then the ETB autotune but ETB wouldn't work)
After, I found out that the fan relay would only activate the fuel pump.
I tried to leave only the 23 pins black connector and manually activate the fan relays with a probe but that would activated the fuel pump as well.
I continued to diagnose the issue today and found out that the pin 23 (power from main relay) was causing all the issues.
I have basic knowledge in electronic but I'm not sure where to look on the board.
I the any diode that could've shorted to ground or something like that?
