Chassis A/C

[David Brady]

Hi George,

Thanks for your help. I tried your diagnostics and found
that the clutch internal resistance is good, but the 12v
supply from the harness is non-existent. I may have a
fuse or circuit breaker issue, but I can't find a fuse/circuit
breaker at any of my load centers that's labeled anything
close to chassis a/c. Ralph, I looked in the outside
compartment next to the pilot seat, but there are no
fuses there for the chassis a/c that I can tell. Any help
in finding fuses is greatly appreciated.

Thanks,
David Brady
