Poll for owners of Diesel powered Monaco/HR motorhomes
This question only relates to Diesel powered Monaco/HR motorhomes. I am trying to find out how many other years have their J1939 diagnostic port wired wrong. On my 2012 Knight it's power supply is from the ignition and I recently found out it should be powered from the battery (always on). In the picture mine is connected to pin 4 of the VCN firewall harness (VCN4 IGN+ DIAGNOSTICS PLUG, ALARM). My question is does anyone show theirs connected to a BATT+ source? You should be able to find this information in your owners guide or on the door of the front 12v wiring/fuse bay.
If yours shows BATT+ as the source please leave a response as to the year, model, and engine.
Thanks

The diagnostic port on my 2002 Dynasty is wired to the battery. I know this because I have a ScanGauge-D.

Here is the picture of what to look for that was missing from the original post. Pin 4 is the one on my coach.

It's wired to my ignition on my 2001 Diplomat. When the key is off my scan-D goes off

I can power on the ScanGauge-D without ignition -- a convenient feature. It will eventually shut itself off. That means power is constantly available via my diagnostic port.
