Dear Ralph:
My brother in law has a 2005 Ski Doo Rev Renegade 600 SDI that he is having considerable difficulty getting repaired. His problem is that after about 60 miles of riding his battery goes dead, and then so goes the sled as the SDI cannot live without 12 volts.
The first dealer felt it was a bad battery and replaced it, guess what? 60 miles later, dead. The second dealer can’t find anything wrong, it’s back there now for the second time. My diagnosis without any tools or training is that the sled is not recharging the battery. If the sled sits for an hour or so, the battery seems to regenerate enough to let the sled run for a few minutes, then dies again. If the hand warmers or thumb warmer is on, then the sled dies quicker. Any hints or ideas?

I agree, it sounds like the battery is slowly being drained and not recharging. This is most likely a charging/rectifier problem. It is very possible with the 3 phase charging system on this sled to have two legs charging and one not. This will slowly draw the battery down, and the end result is what you have experienced. You (or your dealer) need to do a very simple visual inspection of the stator/rectifier/regulator connector. It has been found that sometimes one of the 3 yellow wires that come from the stator through a 4-wire plug in is in the wrong position. This means that one yellow “power” leg is not connected to the regulator hence no charging current from that leg.
The 3 yellow wires (on both the male and female connectors) should be in #’s 1, 2 & 3. #4 is left empty. If the regulator & stator are wired correctly, then the regulator itself may be faulty.
These are simple tests any competent dealer should be able to perform. If the dealer can’t figure it out have them contact their Ski-Doo service dept hotline and their guys will walk the dealer through the procedure.
