There are several things that will cause a capacitor to blow.


The biggest reason is that it is the weakest link in the genset - they simply go bad.


Other things that will cause it are:

The set surging (not running smoothly - revving up and slowing down constantly)

Over loading the genset

A short in the windings of the set.

Bad diodes, if the set has any
