Hello from the Diesel side of the tracks.

My 87 300D keeps blowing fuse 7 (ACC). I traced it to the (ND) compressor clutch drawing about 20-amps. FSM says it should be 4.20-amps cold, 3.75-amps hot. Ha! AC cools as it always has with 20-amps to the clutch.

I don't hear of this being a common issue so I plan to head to the PnP for a clutch off a 300E. The FSM makes it sound easy except for "On vehicles with 6-cylinder engines remove A/C compressor." Uh, I'm gonna try in-situ first. I'm not giving up the R-12 in there. Anything I should know about this job beyond what's in the FSM?

Thanks,
Sixto
