All, 
what I found is the SSI & amp-l-start both failed.  I have installed the ML-ACR and will get to the switch next.
2nd problem, Leece Neville alternator has failed internally that was causing a battery charger to surge from float mode down to 70% about every 5 seconds.  This only happened when chassis master switch was turned “on”.  So I’m in the process to either rebuild my LN or I’ll get a DR 28si (I am still researching how to hook this up through the ocean of posts).
hope this might help others troubleshoot their charging system.
happy trails & happy Thanksgiving.

How often do you run the generator?   If it’s not exercised properly, the temp sensor can get corroded and bridge itself (not contacting any fluids).  That or a thermostat is not a difficult repair but if access is limited it could be (I’ve not seen a non-slide gen install so I have no clue).  
My temp sensor was heavily corroded over and broke when trying to remove.  It took a right angle drill and some countersink bits (the Ryobi brand from Home Depot) to get through the blockage.  I removed the thermostat and fluid level in the pipe to below the sensor and inserted rags to keep drill cuttings from going down pipe system.  
 
If you can remove the thermostat and some fluid, you could use a mechanics mirror to see if the sensor is bridged over or not… again if access allows that.  Just thinking of some easier steps to help verify the issue.  Note the fluid level below the t-stat so you can replace it.
Good luck.

Yes, it still works but I am getting quite a delay before it engages.  I took apart and cleaned everything and adjusted the rocker inside thinking that over time, it’s sprung which requires nearly bottoming out the pedal to engage.
