Got a 06 Magnum 330. Turn key on and HOT and check engine flashes on the display. Jumpered 12 volts to oil cooler fan and it runs then jumpered connection to thermistor in oil cooler and fan doesn't run. Checked resistance of thermistor and its 76.0 ohms. Other forums claim Polaris has this problem with 04 and 05 Mags and did recall. Also was just gonna replace thermistor and part comes up as "not available". Also maybe that there is circuit breaker or fuse in the fan circuit or/and a PDM ECU ....can't find any info. Any help appreciated...either advice or electrical schematic. Any way to jumper over diagnostic plug or do these even have a way to pull fault codes out of the ECM or PDM or whatever its called. Know nothing about Polaris but can fix a Peterbilt or Western Star or Mack.
