# Maintenance
You have to flash the magnetic field of the generator if it looses its magnetic field. Residual magnetism in the generator exciter field allows the generator to build up voltage during start-up. This magnetism is sometimes lost due to shelf time or improper operation, among other reasons. Restoring this residual magnetism is possible and is sometimes referred to as "flashing the exciter field". [^flash-batteries]
Furthermore, we could get a flashing module to automatically flash the generator. Another option is to use a drill to excite the magnetic field again.[^flush-1]

__Step 1__ [^flash-2] </br>
Start the generator. Check the circuit breakers. Reset them if they are tripped.
Step 2__Step 2__ </br>
Insert the steel rod into the chuck of the corded drill. Tighten the chuck.
Step 3__Step 3__ </br>
Insert the other end of the steel rod into the cordless drill. Tighten the chuck.
Step 4__Step 4__ </br>
Plug the corded drill into the generator. Make sure both drills are set for forward (clockwise as viewed from the handle) rotation.
Step 5__Step 5__ </br>
Hold both drills tightly. Press the trigger switch of the corded drill.
Step 6__Step 6__ </br>Press the trigger switch of the cordless drill, so that it spins the chuck of the corded drill. The corded drill acts as a small generator to feed current into the windings of the larger generator to magnetize the field and force it to start working. When this happens, the corded drill will start fighting against the cordless drill.
