I do want to confirm a 12V Sanden clutch will pull in at a lower voltage. No explanation for why I didn't try it earlier since a compressor has been sitting available for months. I do not have a 6v battery but I do have a 50A battery charger which, when the clutch is engaged, is delivering 7.25v. Clutch current draw at that voltage is 1.58 amps. It does sound a bit slower to come in and I have no way of checking how tightly the clutch is grabbing but with Dwight and apparently others having no issues, perhaps this is something worth looking into further.

I also think it is worth looking into the possibility of one or two 6v heater motors being substituted on a typical hang on unit--or even a trunk unit. I know other forums have mentioned the possibility but not sure how (which unit) or if they did.

The heater motors are smaller but available from several Ford and Chevy places--maybe even our vendors. The shafts are smaller but 1/4 to 5/16 shaft adapters or extensions are readily available from several places or could be made. If the original wheel on a unit was not suitable, plastic blower wheels in several sizes are all over the place and many are reversible so motor rotation would not be an issue. The issue would be that I don't find any dual shaft 6v motors--just singles. The typical aftermarket hang on with motor in center and dual wheels would need some thought--but also workable.
