Small Engines (Lawn Mowers, etc.): John Deere RX 75 Recifier, ac volts, plastic casing

Question
QUESTION: Hello John,

Hope you can help me.

I have two John Deere RX 75s that have severed me well for a good number of years.

At this time of year, I use one to mulch the leaves and the other to bag them. I started the process the other day to discover one had a melted fuse. The fuse was not blown but the plastic casing was melted.
I replaced the fuse with the correct value and now discover the battery was dead. Charged the battery started the engine, no problem, them a puff of smoke came from the rectifier.

Your thought please.

Thanks Thomas

ANSWER: Hello Thomas:

What is the Charging System Output when the Engine is at Full Throttle (Checked at the Battery Terminals)? Has the PTO Unit been Giving any Problem? Thanks.
