M1010 A/C questions.

[KamikazeKunze]

Hello everyone,

I have a few air conditioning questions for the 1010.

1) the fan for the a/c will run even if the master kill switch is off. Is this normal?
2) the unit has been converted to R134. It was overcharged so I bled the pressure off until it was in the green. The compressor still doesn’t turn on.
beside the two 30amp fuses (Cab compressor & Box fan) is there another one I should be looking for?
3) I’ll hook a direct power lead to the compressor but I’m unsure which lead. Green or black?

thanks a bunch

One part. Put 12 volt power of the green wire make sure the black is grounded good

Gralmk,
thanks. I recharged the system tonight and nothing. I then ran leads from the battery to the compressor and it would fire up but I still wasn’t getting cool. Of note we tried this 3 times and on 2 and 3 the clutch wouldn’t fully engage. After the 3rd I smelled a bit of clutch material (not good) so not only do I not have power with the harness to the compressor maybe my compressor is shot as well.
thoughts??

thanks

Other than troubleshooting through the TM check list no, sorry, but it requires hands on testing. It does sound like you have two separate issues. Unit not cooling could also be low Freon! I believe there is a cutoff switch, if the unit is low it shuts down, Mine did, then after recharging it worked! Well, it did after we check and fixed a few other issues. Also there might be a fuse in the stock fuse box, and I know there is a relay under the left bench in the back. So as you can see, too many if's! The TM is your friend, both 20 and 30 level books!

If the compressor isn't running how are you telling if it is over or under charged?

The compressor will run when I run my own leads the first time, then subsequent runs it tris to engage but can’t or doesn’t. When it was running is when I checked the charge.
