When I start this UTV, the starter seems to bind up, then it takes off and the engine starts right up. I charged the battery, and tightened the terminals. This is a new unit. The battery is a 330 cca unit. The terminals were clean, but I haven't checked the wires at the starter. Any ideas?

 

Thanks

Since you say it does it right before it starts, could be the compression stroke is putting a heavier load on it and slowing the starter down.

although most utvs have a compression release on the valves for ease of starting.

Could be something as simple as a burr on one of the gears binding it

how many HP is the engine?

330 cca should be more than enough.

Virtually all small engines have a compression release, it's usually placed on the cam shaft and provides a bump to the exhaust valve during start up.

It could simply just be a common occurrence on these machines

Thanks, Travis. I got an email from a tech at Massimo, who advised that this is a common occurrence. He says that it will do that on the compression stroke, and since the compression ratio is high on these engines, it tends to bog down the starter.

Starter motor Massimo T Boss 410 UTV.  The starter motor will sometimes stall at compression stroke. Battery wires are to small to carry the amperage the starter motor requires. When the motor stalls it uses a lot of power and heats up. It will burn out the windings in the motor. Massimo part number for the starter is 24101.

      2015 MSU-500 crank - no start
      By Prepper
      I'm working with a 2015 MSU-500.  Basic symptoms are it cranks well, but will not fire.  It has spark, and it has fuel spraying out of the injector (and spraying starting fluid into the throttle body and plug hole makes no difference).  It has compression.  I bought it not running, and no other information was available.  It has 775 miles on it and 127 hours.  It looks to be in very good shape.   Previous owner replaced fuel pump, ECU, coil, plug, and the fuse/relay box that mounts on the firewall, then gave up.
      My questions relate to cam/valve timing, considering the symptoms and diagnostics so far.  My thinking was the woodruff key sheared off and the crank spun, making it out of time.  My question is, by the pictures attached does anyone have an opinion as to the cam/valve timing being correct?  In the crankshaft picture you can see a timing mark visible.  In the camshaft picture I have arrows directed towards what I think are timing marks (which appear to be exactly 180 degrees from one another).  However, the long arrow in what appears to be bolt configuration in line with the piston/rod line.  Here is a puzzling note... in the position you see in the pictures... I have valve lash on both the intake and exhaust.  I think it's at TDC, given the visible crank timing mark and valve lash on both valves. 
      Any thoughts ?  Does this appear to be in proper valve time ?  Have I missed anything simple ?  Thanks in advance for your input.

      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.

      Code Reader for Delphi MT05 Coleman UTV 400 Hisun
      By Homeowner A
      Is there a code reader available for the Coleman UTV 400?  I tried using the HUD ECU Hacker software and cables/adapters but no luck OBD to delphi 6 pin and KKL VAG as well as ELM327.  Will not connect.  I was able to get it to connect randomly a couple of times, but haven't been able to since.  I was able to clear and read the codes briefly.  I'm aware of the Tiny Scan 301 but it doesn't seem to be readily available.  There's a few out there but they are expensive.

      HOWTO- Code Scanner & Read Engine Parameters
      By aefron88
      This post will explain how to hook up your PC to the ECU of a Hisun/Coleman/Etc UTV to be able to read error codes & engine parameters for troubleshooting purposes.
      This is applicable to all small engines using the Delphi MT-05 ECU. This should cover all fuel injected Hisun models, as well as various other Chinese FI engines, as the Delphi MT-05 ECU seems to be the favored ECU solution.
      Even though we get actual engine error codes to display on the dash, sometimes we have “pending codes” (not yet confirmed by the ECU) or other intermittent issues that are hard to diagnose, for example a poorly connected sensor that may give intermittent false readings, or a sensor that’s putting out bad date, but not bad enough for the ECU to realize.
      The setup requires 2 cables, which are available for around $25 combined, a PC with a USB port, and some charityware software called “HUD ECU Hacker”. This gives the same functionality as the $300 dealer code scanner for a fraction of the price.
      In searching I found info about HUD ECU Hacker, but I have yet to see info anywhere about how to hook it up to a Hisun, so I took the leap and bought some cables, and made it work. I will show a step by step of how to do so in post two.
      I will be breaking this down into 2 posts:
      Delphi ECU Info & Overview (This post) System setup & use Delphi ECU Info (Skip ahead to the next post if your eyes glaze over technical details)
      The Delphi MT-05 ECU was developed to allow small engines to use fuel injection. A fuel injection system requires feedback from various sensors to operate efficiently. This feedback allows the adjustment of ignition timing, fuel injection volume, etc to efficiently and cleanly produce the most power possible from a given engine.
      The MT-05 ECU has a number of sensors that are required for proper functioning including; Coolant temp, crankshaft position, intake temp, intake pressure, exhaust O2, throttle position, as well as some other optional sensors that are used on more complex vehicles.
      From the sensors the ECU adjusts: Fuel injector timing/pulse, Idle air control valve, and ignition coil

      The Delphi MT-05 puts out diagnostic data, however it is not ODB2 like a modern car, where is where it gets tricky reading it. There are three options, there is an old 16 bit piece of software Delphi has that is not able to run on a modern computer, there is the motorscanner tool for dealers ($300), or there is freeware HUD ECU Hacker with the proper cables.
