Update:
I now have the whole generator completely disassembled - if one looks at the active components it can only be diode on the rotor, or the capacitor in the exciter winding. On the passive side - it can be any of the windings - but these are really heavy gauge copper - so hopefully the inherent design of the generator is such that these are never overloaded for their size.
After much frustration - I finally have access to the rotor and diode - there is only one. I took it out of circuit and tested it to be open circuit in both directions. I have ordered a new diode, and will get everything back together next week. I have also ordered new capacitors - this generator has a 30uF and a 2uF connected in parallel - so will test the old and new when it is running again.
If anyone needs to go through this disassemble process - please contact me as I can try to guide you through how to get this accomplished. I think the workshop manuals are not available as there are a few different generations of this product in the field, and maybe the documentation has not been able to keep up.
More to follow as I assemble.....
