      #1   While troubleshooting an issue with temp warning light I discovered another temp switch mounted in the pipe going to the head  The two switches are literally 6 inches apart.  Does anyone know what this third switch is used for?  If i can figure out how I will post pictures.
      Author #2   Finally got the pictures took.  See the photo and tell me if you know what the switch on the right is.
      It looks to be factory and I know the girl who bought it new and she didn't install it.
      I can't find anything on it in any manual i have looked at.  Any help would be appreciated.

      i purchased a brand new massimo tboss 410 and from day 1 it wont operate in reverse.  When i pop in reverse and give it gas it will die out.  when i pop in reverse sometimes in will die right away (before giving any gas) and 1 time out of 100 when i pop in reverse it will operate perfectly fine.   and yes, it operates perfectly dine in normal drive H and L.  any thoughts??   when i called the dealer i got it from they had no idea.

      Hello I am new here but have had this machine for about 5 years. I am having issues with it surging and sometimes sounding like a small backfire thru the intake.  When putting in low, high or reverse it will struggle then go full power then struggle. It will only do the small backfire thing while in neutral reving it many times. Once in awhile it will throw a check engine light.  
      Parts replaced/checked:
        I have checked the valve lashing, timing and adjusted. Parts replaced are the coils, spark plugs, injectors, fuel lines, fuel pump, IAC sensor, TPS sensor, throttle cable, speed sensor, primary and secondary clutch and belt.

      Hey guys! Newbie here. I'm an old man who's better with plowing a mule (4-legged kind) than these newfangled beasts. I, and a friend of mine, just bought new Coleman sxs and are having to finish the assembly. I've been reading on this site and I'm falling on the mercy of you experts. The only way I'm an expert is that an "ex" is a has been, and a spurt is a drip under pressure. LOL First off, the 2 buggies have no ignition switches. They seem to mount on the dash, not the opening in the steering wheel shaft cover, so we ordered new ones that are supposed to fit. They are 8 inches long, and have a 4-wired white plugin which is slightly rectangled when looking at the end of the plug. The trouble is there's nothing to plug into. There is a three-wire grey plug close enough to reach the four-wire plug, but of course, they are not compatible. 
      Secondly, the blinker, light, ect. unit on steering wheel just spins around when touched. I see no way in heaven or earth to secure it. I've looked at a diagram on the Powersports site, but can't detect how it mounted. Fellows I'd be so grateful for any help with this. Me and my mule will even plow your garden for free, for your help. LOL
