  So thanks to those that replied to try to help for my thread:

  https://ogm-energy.com/community/ogm-user-forum/topic/89665/p-van-opt-2-harness

   

  It was determined that the wrong harness was used for my Nations second alternator and WS500.  I had a "P VAN OPT 2" harness that was meant for Lithionics canbus battery system.  I need a harness that is not canbus and that uses shunt information for current flow.  It is being sent to me ...

  My question is - has anybody had any exerience splicing into existing (already installed wires) to a new harness.  It would make things SO much easier.  I really am only talking about 2 wires that go from my inside RV WS500 out to the alternator. 

  I have one dark blue wire that connects to my Field connaction on teh alternator and a larger black wire (the alternator temp sensor)  - I actually already cut my existing harness balck wire.  It is insulated (like a coax cable) with three wires inside - an insulated black and red wire and an uninsulated silver wire.   I was hoping to splice each wire and the recover with shrink wrap.   Has anyone had any experience with splicing for repair or anything otherwise the WS500 harness wiring ??

   

  Thanks

  If your batteries have No CAN, it is usefull to connect the 2 shunt wires to the shunt at the batteries.

  But without shunt wire the system will work also.

  It dont explain, why the system dont charge, or why it stopped charging after 4 hours.

   

   

  I can not follow what you wrote about the black cable end  blue cable.

  The Blue (field)  and black (tempsensor) on alternator side have nothing to do with the CAN cable or the shunt cable.   The CAN and shunt cable will not be routed to the alternator at all.

   

   

  The cable can be rebuild, BUT IF you make any fault rebuild the cable the WS500 can be damaged.  It will be visible on the board from WS500 why it was damaged, this means NO warranty on the WS500. Rebuild the cable can only done by technician who knows what he is doing. Not something to learn from Facebook or Youtube.

   

  But as a technician I would choice rebuild the cable, becasue it is easy and it is much easier then install a new cable.
