ThermoKing Tripac bogs down when A/C is on

Hello everybody, I was wondering if anyone could help me on this problem. I have a 2006 Thermoking Tripac Yanmar 270 that I just recently added A/C to. A brand new condenser, drier, condenser fan, and hoses. Everything runs fine with the A/C off, but once the A/C compressor kicks on and the condenser fan turns on, the engine starts to bog down and run really rough but doesnt come to a halt. If anyone has any ideas, please let me know. Thank you very much.

 

Sounds like a weak alternator possibly?

 

I replaced the alternator as well, my apologies for not stating that. It was a thermoking original part not an ebay one

 

It will a little, turn up the idle if possible,

 

Idle is already at max

 

Has the fuel filter been changed?

 

Yup both fuel filters have been changed along with the oil filter

 

Brand new fuel pump as well

 

Sounds like the injection pump governor is going bad

 

Possible bad compressor if it wasn't changed or high head pressure.Do you know how much freon was charged in the system
