[TG] EV-1 Error Code "No Seatalk"

[VT2C]

Oh Wow, the terminators! Didn't realize they had to be in place, but hopefully that will do the trick, and thanks for the heads up on the solar charger.
Thanks Tom.

Usually this is one of 2 things:

1. Incorrect layout of STNG network, e.g. something other than the required 2 network terminators (blue blanking plugs, must always be exactly 2)
2. EV running old software compared to the ACU. There is a known condition where if you have old software on the EV and new on the ACU then that can cause the EV to continually reboot. The solution is to unplug the ACU, update the software in the EV through a multifunction display (MFD) and then replug the ACU.
   

To this, in your system, I'd add a question mark about the solar charge. We frequently come across poorly-regulated solar output which might look like a stable 13V on a multimeter but is in fact anything but stable when you look with something more sensitive (oscilloscope.) That doesn't matter for batteries, but it does with more sensitive electronics. The same, by the way, can apply to other non-DC charging sources.

If I had to hazard a guess though, I'd say terminators not fitted or not fitted in the right places.

Regards,
Tom
