Flight1 BN Islander - Generator Undervolt lights

[Rich_Cooke]

I don't know if anyone can help but I am having trouble which SimConnect Variable/FSUIPC Offset is behind the operation of the port and starboard Generator Undervolt lights on the Flight1 Britten Norman Islander. I am trying to work out which values illuminate/extinguish these lights so I can emulate that in my panel set up. I'm sure this is down to my lack of knowledge of FSUIPC logging. It looks like it should be "2880/2890 8 Generator alternator 1/2 bus voltage" for both engines but if I monitor these it stays at zero throughout during the start up process. Hope someone can help me sort this out.

Thanks Rich Cooke
