Blue bird ac questions
I was referred to you I’m helping a friend on his bus . This is my first time working on one .
Two compressors top one 135 -A conversion
Bottom one looks like R-12
I need to jump out the low pressure switches can I do that at the terminal strip by the drivers side.
So two evaporators w/ TXVs
But the condenser has me stumped it had two 1/2” lines tee’d on the left top and two lined tee’d on the right top side of the condenser .
Are fuses behind the toggle switches / control board for the fan switches and high low cool.
Where could I find the wiring diagram for the buss
Is there a refrigeration circuit diagram
Can I drop in 409-A so I don’t have to change the oil on the R-12 system
Do you charge with sub cooling ?
