Hey guys.
I just picked up a 2006 Switchback 600HO for a project. It has 7559mi & 125psi compression on both cylinders. The previous owner had issues with the kill switches and temp light and decided to sell for a steal of a deal ($1k with an almost new 1 3/4" track, cover, 2-up seat, etc.).. thus here we are.
The sled fires up no problem but neither the Kill Switch, Tether nor Key will turn the machine off.. I've checked several ground points from Engine to Chassis, Harness to Chassis on the clutch side, CDI to Chassis Connector, handlebar connections, tether and ignition connections and all are good. I've pinned the CDI for continuity (E5 for kill switches) to multiple points in the harness right up to the handlebars and all is good. I checked the switches for functionality and all works. I checked all the harness /connections I can physically see without the engine removed and all seem solid. No chaffing, burning or breaks. I've never owned a Polaris prior to this one and I'm not sure where else to look for issues other than the CDI.
The sled has working headlights, hand warmers, electronic reverse, taillight, MFD and gauge which tells me the regulator is working properly. The sled runs along with all electronics functioning so I believe there shouldn't be issues with the Stator(?).
The temperature light is also lit up constantly on the gauge and the MFD is displaying "ERR" under the engine temperature section. The sled is in a de-rate condition (timing is retarded?). I tested the sensor with a multimeter and found that it is functioning properly on that end. I rigged up a bypass using resistors to simulate a good temperature signal and the result was the same. I then checked the wiring back to the CDI from the coolant sensor (E11 BK/E12 BN) and found the wiring to be fine.
Since both of these functions are controlled though the CDI, I somewhat feel that it could be the problem but I am in unchartered territory. Anyone have opinions about areas to focus on or previous experiences which were similar? Are there any common points between these two issues that could be more obvious to someone with experience?
I do have experience in electrical systems as well I have the wiring diagram for a 2007 Switchback 600HO CARB which should be similar judging by what I've seen so far.
Thanks
