1097R1 with a 200A gen intermiten charging issue

Venio said:

I got a 2005 R1 form the auction a little over a month ago. Pretty much all operational beside LOTS of loose stuff that Red River Army Depot had left. I'm going to rant about this some other time. However, there is an odd issue with the generator. It will ether start charging with a little delay, a lot of delay or not at all. Anther odd thing is the time it takes for the Wait light to turn off. Usually if the time is too short and the engine is cool it will start but the gen would not come on. At first I though it got to be the voltage regulator but those things usually ether work or they are a toast. I'm not sure how the protective module ties in with the generator, but it definitely does not act right. I went trough some of the connections and used dielectric grease to better the contact, HMMWV dwells now in pretty humid and corrosive environment.

When it is not charging turn on the heater fan and see if it is working, if not it is likely the EESS (protection) box not feeding exciter voltage to the alt.
There is a relay in the box that does that and they can go bad.
It is normal for the alt to delay after starting it is called soft start.

Is this something that can be repaired or should I start looking for a EESS box replacement?
