over-voltage

[n86121]

While a diode, that is technically a high current rectifier. Allows each alternator to 'pull' current onto the power bus. Yes, if it is internally loose, then its shot. It could have been unloading and reloading the load and all sorts of mischief.

If you have trouble finding a 'cessna part,' I might think any common 100 AMP rectifier will do the trick, anything way above the current an alternator can actually produce. Modern rectifiers will also have less of a voltage drop, so everything works easier.
