    You might want to inspect the cond fan wires where they are strapped to the underside of fan bracket.
    Sometimes Bruno at the factory cinches them down really tight, and a wire may just happen to be resting on a weld joint on the bracket. If the joint has a little sharp piece of slag....
    POOOOF!!!
    Sometimes they will blow clear and ohm out ok and all fans will work fine, But after time will work their way back to a short condition.

    I ordered three motors for an RTAC because they blew fuses and didn't ohm out correctly. Put the new ones in and NADA, felt kinda low for awhile.
