1992 245 Intermittent Charging Problem Alternator Exciter Voltage Low 200

Hi everyone!

After my cam seal change and degreasing the engine, I've got a intermittent charging problem. Sometimes it's charging at a full 14.3vdc, other times nothing, with the dim warning lights. When not charging, the voltage on the alternator exciter wire is 6.3vdc while the engine is running, and 9.4vdc when the engine is off.

The brush pack/regulator have plenty of brush length, only 20k miles. There was some oily residue on them from the cam seal, but I cleaned them, and what I could inside the alternator. The exciter and other connections looks clean.

Possibly there's still some oil inside the alternator causing the problem? Why would the exciter voltage be so low?

Any ideas?

Thanks!
