Aboard a Learjet 35* and Learjet 55* aircraft, the generator control panel controls the voltage for generators that charge batteries, start motors and control the ground power unit. When working properly, these generators share the electrical load. But if upon aircraft startup the amp meter registers a different reading for the right-hand and left-hand generators, you have a paralleling problem due to faulty relays which will need to be replaced.
The relays are located behind the generator control panels and not easily accessed. Removing the control panels is a difficult job and once removed, I highly recommend that both relays (K5 K6) are replaced at this time, even if one is not faulty.
