Kirloskar Generators are fitted with Stamford make alternators. One of the most common problems with alternators is no-voltage build up due to loss of Residual magnetism.
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" which is explained in this video.
