I have a 2012 Bennche Bighorn 700X.  I bought it used.  It had been sitting in a field for several years untouched.  I put a new sun gear in the shifter, new shifter linkage due to the old one having been patched, and a new battery (and of course fresh fuel).  The machine cranked and ran beautifully.  I had it over a year and then the machine quit running.  As it would not stay cranked, I narrowed the problem down to a bad IAC valve.  I replaced it and it ran as good as new/old.  Fast forward, the machine started to act like reverse wasn't catching and would not always back up when in gear.  Then forward quit.  I assumed a bad CVT belt and got one.  Started removing the bolts from the cover and (3) just turn in the housing without coming loose.  (2) are on the bottom, so very little room to do anything with them.  I tried cranking the machine again to see the belt move since I can move the cover enough to see the belt and now the machine will not crank.  It turns over fine.  It gets gas to the injector and has spark.  I can spray cleaner down her throat and she would run until it ran out.  I have replaced the IAC twice and put a new injector with no change.  I went out and put the old injector back in to see if that made any difference and, well, it did.  I tried to crank the machine and the starter is stuck trying to turn the machine over even with the key off.  I have to disconnect the battery to stop it.  Before I shoot this thing, what am I missing?  Is this an ECM problem or something else I am not seeing?  Been dealing with these Gremlins for over a month now and weeds are starting to overtake the motor due to it not moving.  I would love to get the thing running first and any ideas of getting those CVT cover bolts out would be extremely helpful.  Thanks in advance.

I have replaced the injector, fuel filter, and IAC valve.  I get plenty of fuel up to the injector.  So, after finding the battery was dead, I put the charger on it.  It never would charge.  Pulled the positive cable off and it charged.  I attempted to reconnect after the charge and the starter engaged with no key in the ignition.  I let it sit for a while, went out and pulled the wiring to the solenoid by the battery, checked it all the way to where it connected, and then reconnected the battery cable.  Turned the key and everything is back to normal with no zombie/ghost starter.  I sprayed cleaner down her throat and she starts and runs.  She runs longer than normal and then dies.  Turn the ignition over and it cranks and dies immediately.  If I keep my foot in the throttle, it will run.  I know the last time it did this was the IAC valve being bad.  I know new parts can be bad.  Could I be looking at another bad IAC valve or something else?

      Sector E1 Battery change out
      By Gorj
      I am going to replace the batteries in my E1. I am not interested in the high cost Lithium or the expensive 6 volt dry batteries.  I am considering four 12 volt deep charge marine batteries. I have a source for 810 amp units for about $100 each.  I have no worries about reprograming the charger because it went out a few years ago and I replaced it with generic golf cart charger. When I decide to do this, I'll keep you posted on the results.

      Want a new work UTV; who and what should I look for?
      By FTG-05
      I want to ditch my Kubota RTV-XG850 and its moronic twitchy throttle design flaw, get rid of the problematic engine and the 40 mph purposely throttled speed.
      So far, I'm looking at the Honda Pioneer 1000 and the Polaris Ranger 1000, both of which have 1000-1500 lb payload bed capacity.
      What other makes and models should I be looking at?
       
      Thanks for the help!

      Hisun Sector e1 Battery replacement: any tips?
      By didgeridoo
      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!

      Battery Life
      By Gorj
      I am into five years of ownership of my electric side by side and I am noticing some deterioration of power. Although I measured the voltage at over 49 volts, I believe the batteries are beginning to fail. I charge them about twice a week. Last year the charger went out and I replaced it with a 48 volt golf cart charger.  What has been your experience with the batteries?
