Sanden 508 Wiring
Hey wondering if anyone could help me out got a new sanden 508 for an original ac truck and need to wire it. A black and a dark green wire go into the og compressor. The sanden only has one black wire. I’m assuming that because the dark green is switched 12v from the poa valve/pressure switch that, that dark green wire should go directly to the black wire on the sanden? Is that the case? Have any of y’all done it? Is there another way I should be wiring it? Anything helps thanks!

Dark green is hot and the black is a ground with a diode if I remember correctly.
So yes you would tie the DG into the new compressor for 12 volts. I'm not going to say use the black without you furnishing a picture of it though to confirm.:chevy: |

Look at the 1 minute mark and the clutch only has the single black wire. He says the coil is grounded so the black wire has to be the hot wire for the green to connect to. If you have a voltmeter measure the ohms between the black wire and the coil. If you get some resistance then you are reading the coil windings resistance and the black wire is the hot wire and the coil is grounded to the compressor body.

Thank you I think we are in the same page and I’ll do some testing this afternoon. But it would be awesome if you link directly to a YouTube video I’m fairly sure my yahoo isn’t pulling up the same video. Another question closely related would y’all know what this little connecting wire with a black ball(see picture attached) on it is because if dark green is power and black is ground they shouldn’t be connected right?

That's the diode Andy spoke of.. It "clamps" the voltage spikes created when the magnetic field collapses as current is removed from the coil windings..

Re: Sanden 508 Wiring
So that black diode shouldn’t be necessary for the sanden?
