Yes ..that is what "Operators Position/Direction of Travel" means.
..R15 is the Ceramic resistor ..referred to as Aux Fan low speed pre-resistor.
If you jumper 12 V to include the R, you get low fan, if you jumper to the other side, you are by-passing the R and you then get High fan b/c by-pass gives you full Bat V.
This is just a mid-circuit test point we use to make a rapid diagnosis on lack of aux fan complaints........it is very common for these terminals to burn off b/c of the heat of R15..this test does not require key ON or any other chassis controls , as it is a direct battery jumper test, the same as if you had the fans on a Bench and were testing them with Direct 12v....which is why I posted if the other poster had a fan w/jumper , he knows he does not have ground problem on fans as he suspects b/c they would not come ON with this test as you are not bringing neg power over from battery..you are picking that side of the completed ciruit up from the chassis ground..so that ground diagnosis is included in the test results. If he gets No fans with the bat pos jumper after R15, THEN the suspect can be a bad ground... [ or bad motor].......... If one gets High fan , No low fan with the jumper test, you know the R15 is open...........Simple
