BuildCraft version: 7.99.17
Forge version: 14.23.4.2708
Link to crash report or log:
Singleplayer or multiplayer: Singleplayer
Steps to reproduce: Put any RF emitting device (not a buildcraft one) like a solar panel, and the quarry will not work.
Additional information:

After 7.99.0 buildcraft produces and consumes MJ, which is different to (and separated from) RF.
