Hisun 700 fuel pump wire harness

Recommended Posts

Hi,

Don't know much about anything utv but I figured out my fuel pump wiring harness needed to be replaced. Installation looks pretty straightforward, plug into fuel pump and plug in the two pigtails. Question is: one of the Pigtails on the old harness I am replacing had a splice in the black wire and attached to a bolt on the engine. Is this necessary?  Is the black wire, I'm assuming it's the ground, grounded at the other end of the pigtail?

Sorry not best picture but black wire on right is spliced and attached to motor screw.  Im thinking the wire was broken and this was done as an easy fix?  I purchased this used.

Any black wire in a factory harness of a 12V system will be a chasis ground.  It may have multiple points where it connects to the frame.  This is done as 1. A redundancy and 2. To ground separate pieces of the chasis that are electrically separated by a urethane suspension bushing.

Also, the closer a ground wire connects to the frame from an electrical component the less "noise" is introduced to the circuit.  Not that big a deal for basic systems but it matters a lot for sensitive electronics like audio and video systems.  Additionally, its "safer" because electrical current runs from negative to positive, so the shorter the ground wire the shorter the current path through a skinny wire is.

      I was thinking of using one of my old head lights as a bed light for The mule, if we're loading fire wood in the dark etc we can see.
      There is a open electrical accessory connector I can plug to and run the wires alongside the roll cage, and mount a separate switch,
      I can just cut the old connectors and crimp on new ones, but does anyone know the name of the type connector this uses, all I can find are the square crimp connectors.

      Hi, I was hoping to find an "in-color" diagram, at least, of the wiring from the speedometer and where all the wires are connected.
      The entire wiring of the entire side-by-side would be wonderful!!!
      I purchased a used 2008 Joyner Commando 650 2 seater from an individual and they butchered the wiring...something has come lose and I cannot for the life of me tell where it is supposed to connect. It is a ground wire and is till connected to the frame but I don't know where else it is suppose to connect.
      What makes me think it goes to the speedometer is that when it came lose, the speedometer immediately stopped working.
      If anyone can help me with this, I would appreciate it tremendously. There is nothing on Joyner's website...and I already looked on YouTube to no avail...might be something there but I could not find it...

      Hi,
      New member from South Louisiana. I have an American Sportsman UTV with a Subaru/Robin EH65 twin cylinder 2 barrel carburetor. I had starter trouble (solenoid) and allowed my grandson to pull engine in order to change it. You cannot pull engine shroud with the engine in machine and cannot remove starter without removing shroud. Kid is great mechanic but lacks experience. Putting engine back in and he realizes he didn't mark wire locations. I have schematics but colors don't match what I have. Anyone out there that can help me wire this engine back up?

      Hi everyone, I’m new to the forum and was looking to get some help from anyone that has the same UTV as mine. 
      So I just picked up a 2016 Cub cadet challenger crew with eps. It’s needs work, the guy that I bought it from completely took the machine apart due to needing an engine rebuild, but he also took off some spare parts to keep for his other machine. So basically I’m missing a few electronics, I think I’m missing a relay box and ecu but I’m not sure. I’ve looked everywhere on the internet for some pictures under the hood and can’t find anything. I’ve found part schematics but some of the pictures are not clear.
      Can someone please open up their hood and post a few pictures of that area? There are a few bolt locations but I can’t find what goes there. It would really help me out.

      Hi Everyone, This is my first post.  I believe I have my starting issues narrowed down to decompression springs (good grounds, one way bearing, etc.) so I order them and now I have no idea how to install.  I am handy enough, but looking for a video or other instructions on how to replace them.  If this has been covered and I just can't find it, appreciate some input on where to go.  If not, would appreciate some instruction!  Haven't done this one before.  Thanks.
