    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
