Oh, I for sure ain't going to start guessing. I am guessing on what to check if you want to say that. But I ain't guessing on what to replace! I always checked to make sure the connectors were pushed on good but didn't think to check the actual wires pushed into the plastic piece. Thanks for the idea.

Alright guys, I checked the chiller out today. Everything was normal. I have come to the conclusion that it is one of the t-stats that is a nuisance trip. If you have been readin along you know that I have already replaced the MCSP, since it wasn't de-energizing the male unload solenoid. But I believe the damage has already been done to one of the stats being I had reset it over a couple of days until I found the problem. It's probably a weak t-stat now and opens prematurely. After coming home and reading your post Manu1, it has to be the case because I have felt the compressor a couple of times after it has tripped and it never felt hot. I didn't know that they were under the terminal plate, but I have felt the suction end where the windings are at, which was cool with a little sweat...all the way to under the terminal plate, which was cool/warm. By the way, where did you get information about the winding stats? I only found what temp they open at and that's all! Thanks everyone for the help.

Resolved by cleaning terminals at comp withs some sand cloth and then connecting wiring and coating with corrosion inhibitor. SP400 I believe, got if from Grainger.
RTAA hi mot. Temp. Resolved
Bklyntek, here, hope all is well. Had a similar problem last
Year. New contract, owner had RTAA070.compB tripping hi
Motor winding temp. Stumped me for awhile, finallyclimbed
On top, found c fans right behind bad. My fault assummed
They were for ambient controlled. Well, changed both and
Never had a problem to this day. At same time, changed
Both oil filters on.compressors. Just thought I'd chime in,
Take care, guys.
