I purchased a J1939 Simulator with the hopes of using Carloop to parse J1939 messages. Specifically, this one:
However, when I plug in my Carloop (with Electron connected), it doesn't appear to be getting any power (the Electron LEDs don't light up).
The OBD port on this simulator is supposed to output 24v. I tested it with a multimeter and it reports 23.2v on pin 16 and between 2-3v on pins 6 and 14 (the CAN pins). Pins 4 and 5 go to ground.
I'm using Carloop 2.3 which I believe is using a stepdown converter capable of handling 24v:
However, something is going wrong somewhere because my Electron never gets power.
When I try the Carloop/Electron with another simulator that outputs the usual 12v it works fine.
Any thoughts on what is going on here?
