In the process of replacing cooling fan motor

I have lower fairing removed and am working my way towards removing radiator.

Question is about fan wiring.
I presume the + is switched thru the thermostat,
but can I assume the -neg is grounded to the chassis somewhere
and if I do a continuity test with the multimeter it'll indicate this or ?

The power feed to the fan comes from the fan relay which is managed by the Motronic unit.

Thanks Inge,

I guess that means my simple  earth concept is not a runner

;-(

on the other hand you may be able to tell me which side right or left is positive,
and I assuming the fan motor wiring terminals are horizontal (knowing my luck they're not)

Yellow/violet wire is power, brown wire is ground...connector you find under the tank.

If you put 12V to the fan alone, even backwards it should run, brown+ and yellow/violet-
(after refurbish I let them run 10 minutes both ways)
