There are several things that can cause this, so more info is needed. Here are a few things to check first.
* any alarm lights on?
* all engine gauges (oil, temp, rpm) nominal? No surging?
* check regulator fuses? (Behind panel)
* check 24v fuse and 50/60 hz setting?

If none of the above, then I would suspect a voltage regulator problem…. There are several posts on how to diagnose this…

Good luck!
