Wakespeed Error #43 Low Voltage DVCC version

I am receiving an error code #43 Low Voltage on the Ekrano GX on one of my 2 Wakespeed controlled alternators after updating settings to enable DVCC (which is fantastic). I will be diagnosing further but have not yet seen the voltage issue on VRM. I also could not find any manual or forum entry on #43 associated with low voltage. Any insights to help troubleshooting are appreciated.


I will be testing adjusting whitespace, and increased VRM log to 1 min to monitor voltage.


Thank you

Matt

@Matt Looking at the Wakespeed configuration and communications guide that is available on their web site. The error is defined as

#define FC_NO_VALT_VOLTAGE 43 + 0x8000U // No voltage has been sensed on the VAlt+ line, blown fuse?

It would be worth checking the Alternator voltage wire and check the fuse/there is voltage on this connection.
