I have a yanmar longhorn 6 seater which I believe is having fuel delivery issues.  It will run off of starter fluid and will sometimes run on gas but will not idle.  Fuel pump is new and verified to put out 56 psi.  Injector is new, I'm reading 10.5 volts at the injector, gas is new.  The unit will run when the engine symbol is not present at the gauges.  Diagnostic port doesn't appear to be present, can't find it where yanmar says it should be.  Oil is full but old.  Any ideas what's going on here?  Is there a maintenance function that will shut this machine down if it has old oil?

I know the Axis/Hisun manual says it has a low oil switch that will shut down that machine if it has low oil.

And a pull start generator gave me a fit one cold day when electricity was off due to a storm. Because the oil change I did a month before. The oil was too thick when cold.

      So I have a Bennche Bighorn 500 that I bought used a couple years ago. Was working fine until this winter when I was plowing and I think it drained the battery. And had a difficult time starting and staying running. Idle seamed really low, and would only stay running if I pushed on the throttle. So I changed the battery, and the acm valve, fuel filter and spark plug it will start up and surgery to 3k rpm but comes back down and dies, unless I give it throttle. I am getting fairly good amount of fuel from fuel pump.  It does spit at stutter right before it dies. What should I try next?

      Hi All,
      I have a 14 mile round trip on level roads to reach the property where I work with my 2025 Amp Crew Ranch (purchased, April 2026).  That 14 mile round trip uses 60% of the battery as shown on the gage for a calculated range of 23.3 miles versus an advertised “up to 50 miles” range.  A mile or two working on the property gets me a flashing gage and warning beeping by the time I get home.  The dealer was good to work with and even with a new battery (yesterday) the results were about the same, although there seemed to be more power and a higher top speed.  I own a Mach-e Mustang so I am familiar with how various conditions affect range, but less than 50% of advertised range just seems like there has to be something out of whack.
      Now I’m wondering if there is a controller and/or software issue affecting the range and performance.  At various points the Amp seems to lose power for no reason and then has trouble maintaining speed.  Any ideas?
      Also, twice now, the brakes seem to have not released fully.  After noticing reduced speed, I stopped and check the rotors and wheel…..HOT!  So, now every time I feel less power, I stopped to cycle the brakes and check the temperature.  Very annoying.  Are there any adjustments to be had?
      And yes, as noted in another post, sometimes the switching from forward to reverse or high to low speed feels sluggish or balky.
      Lastly, while an electric vehicle powertrain is quiet, my Amp was horrible from a road noise and vibration standpoint.  This was easily fixed by locating panels vibrating on other panels or the frame (even the cup holders were vibrating) and installing felt adhesive pads at the contact points (seat to frame, windshield to frame, fenders to frame, etc.).  This is a $10 and 1/2 hour fix that makes a significant improvement in the driver/passenger experience.  Tire noise, yes, but that’s because of the knobby tread.
      I’m trying hard to like my Amp and would appreciate any tips, advice or solutions.

      I have a Coleman 550.  Was having problems to start with where it would start and then shut off after a couple tries. It would take off and be good. It then got to a point where it would not start at all. I replaced the fuel injection twice the second time I replaced it I noticed a mouse or something had chewed one of the wires that connect the electrical to the fuel injector. . So two-part question first does anybody have a part number for that wire harness?  Second, any other ideas after I fix the wire harness permanently on what could keep it from starting I have gas flow up to the fuel injector.

      Hi, I purchased a used Cub Cadet 750 Challenger that seemed like the belt was slipping so I put a new belt in.  It still acts like the belt is slipping but now I am thinking it is the clutch? 
      What is the best way to remedy this problem? 
      Can the clutch be rebuilt?
      Are there aftermarket clutches available?

      My rtv 1140 won't turn over.  I've jumped the neutral switch, and the brake switch, and checked the ignition switch. I'm not getting any power to the trigger wire on the starter solenoid.  It starts fine with the key on and putting power to the trigger wire on the solonoid.
      Does a 2010 RTV 1140 cpx have a starter relay? 
      Does anyone have a wiring diagram?
