MTX-L keeps reseting

[TAMA_player]

So, today my MTX-L start to have this issue.
It just keep starting up over and over.
I tried to change ground, and 12v power. Also changed a spare o2 sensor.
Disconnecting the sensor is the only way to have an error code (e2), but every time i connect the sensor it starts with this issue again.

Any help will be really a appreciated

Where are you taking your switched power from? They really do need and like there own supply otherwise they throw a fit. try taking it from the harness from your key barrel and having its own power with a 5a fuse inline. This worked for mine ever since changing or go with a motorsport fuse power block that give you a few independent power supplys from 1 feed, this is now my new route for multiple gauges

I have a separated direct to battery line for my progressive alky controller and for the wb.
I tried also to connect directly to battery.

Edit: Today i replaced power lines, and in the process the positive cable just breaks, so seems that the issue was a bad power cable.

Oh corrosion in the line would be a good reason for it to do that, glad you sorted the issue.

Thank you ec17pse for your response.

It was the copper wire broken inside the plastic cover, in the original MTX-L harness.
Is good it was easy.
