The brushes may be worn down. The spring tension drops off as the brushes wear. Generators don't like high rpm. They tend to put out less the higher the rpm gets and worn brushes don't help much

A person can perform a running voltage check pretty easy but an unregulated output amperage test may tell more about generator function.
