We are trouble shooting a 22KW and disconnected the controller to check the connections and are now getting a Fix Harness Resistor message . Is this a part of the controller itself or can we just purchase a new harness ? Any help would be appreciated .

The harness resistor tells the controller which generator it is controlling.  If you are getting this message then I would examine the harness and make sure those connections are good ohmed back to the resistor.  The resistor harness connector has to be plugged in first so that when the controller powers up it sees the resistor first.  I would have to look which connector has the resistor but I'm sure it is shown in the diagnostic manual.

Also, check all wires that plug into the controller. I have run into problem when there not seated properly.

plug the largest of the 2 connectors first,this is the one with the resistor.
you can then plug in the rest of them afterwards.

Adding the same attachment from the other post to this post also. Sure looks like it applies here

I don't see why steps 4 through 9 would be necessary. Once the 7.5A fuse, N1, N2, T1, and negative battery are all disconnected there isn't going to be anything else live.

i only completely disconnected the controller and pulled the fuse.plugged the large connector first then the rest of them and lastly the fuse.
