1 Ohm= 13.5 Amp drop, theoretically, which might be enough to prevent worn windings/bearings from turning.
Motors do not like running on reduced Voltage.
Voltage present does not equal flow necessarily.
Higher loads and Amps will be most affected by resistance, up until the point of connections and wires overheating/melting.
The ironic things is the multi-meter uses very little Amps to internally test for resistance.
I also suggest replacement of the FP Relay first for preventative maintenance.
Once had a Bosche that would randomly overheat and leave me stranded in traffic situations.
