Hey there!
A common issue I found over the internet was the fact that people's geothermal generators weren't generating power despite the fact there was lava supply and correct wiring. I even saw people calling it a bug, etc.
I do not pretend to know about power drops in wiring but the solution I found for this problem was to have a batbox immediately after 1 copper cable coming out of the generator.
I presume that this is to do with the power drop in the cables, i'm not sure.
But for anyone who has this issue, this was my solution! :D
