Only Engineering. You need Timers, which precicely giving the Geothermals Input, or better:Im using a grid of 6 geo generators attatched to pumps and they just keep eating lava!
Is there a way to stop my redpower pumps when my geo/pump are full?

They fixed it in minutes, but they didnt release the fix.Its not the only coding issue in Industrial Craft. The energy net has errors too. Hence why it took them so long to track down what was causing, and still is causing in some extreme circumstances, the ghosting bug.
What? I'm pretty certain you could say this to every support request out there and it would be equally true.well considering that most mods have to re write there code for 1.3.2, i wouldn't be surprised if they "did it right"(not implying ic2 was poorly coded). and the issue would just "disappear" yeah know?
