It is the same battery, but it's always been hard to start. I got the UTV in an auction. It was a floor model, so it has been started numerous times. But it's definitely not the OEM battery. It reached a point where the battery wouldn't even turn over the engine without a battery charger hooked up. This battery will turn the engine over, but it is marginal at best. I have to keep hitting the key to get it past the compression stroke. Even then it's a slow crank.

Have you checked that the ground is solidly connected?

Check all the plug connections for solid, tight connections. Including the solenoid, and ignition switch. Check the ignition switch for corrosion, and proper function. 

Really, all this is just making sure that you've covered all possibilities. Because it really sounds like a starter. They can get expensive. Personally, I'd check what I could easily get to. Then I'd pull, and disassemble the starter. Checking the bearings before disassembling. Then the brushes, they can have cracks, and such, long before they wear out. Most starters don't have shims/washers, but if yours does. Make sure you put them back like they came off.

I've checked all the connections and grounds that I could get to. I haven't checked the ignition switch yet. All the connections that I could locate were clean and tight. As soon as I can figure out how to get to the ignition switch, I'll check that.

These days most of that stuff is pretty well sealed up. Getting to it could be a chore. 

To further your diagnosis of the problem. You might try lightly tapping on the starter, while it's doing it's slow starting thing. I usually use the wooden handle of the hammer. It needs to be a sharp rap, not a padded, soft tap, like with a dead blow, or one of those plastic hammer  handles. But hitting it with the hammer head, or hitting it too hard can damage it. So be careful. 

Like I said, I really believe that this is going to be the problem.

Have you tried jumping the wiring with jumper cables?

Go from the buggies Battery to the starter, if it starts fine, wiring issue.

If not, bad battery , starter, or wiring issue.

Every time I've ever tried that. It seems like all I get is lots of sparks, and aggravation lol. But yeah, if you can get to it. That's an excellent idea!

Anything is possible. But I really have no idea. 

If it turns out to be the starter. Then just because this one went bad early on. Is no reason to think that the next OEM starter would be faulty. 

I seriously doubt that you'll find anything built more robust than OEM. Most aftermarket starters aren't known for being built well.

I'd pull it apart, and look closely at the brushes, and bearings. Maybe there's a kit available?

$110, not bad.. you might check with Arrowhead  to see if they have one that will work.

. but one thing i just thought of, you might ought to check Voltage in 2 places, on the battery side of the starter solenoid, and the Starter side of the solenoid, in rare cases, a solenoid can work, but not pass full voltage/amperage through it . i've ran into it twice on a Murray and JD mower.

Does your starter look like this?

Or is the solenoid piggyback?

That's what mine looks like. PITA to get to. I can't see how to get to the ignition switch without removing the entire front body. The starter solenoid is behind the battery, facing rearward. Looks like that will require a removal of the front body, also.

We already know that it works. So if it's not under load, then it's natural for it to spin like there's no problem. 

Check the shaft for side play. There shouldn't be much at all. Then you'll need to gently disassemble it, by loosening the thru bolts. 

Or at this point you can just take it to a starter rebuild shop. They should be able to find the problem pretty fast. Either way, I'd want to be certain that it's definitely the starter at fault though. 

It's extremely unlikely that they'll be able to fix it. Because they won't have the parts. But if they'll confirm that the brushes are bad. Then you might be able to find those somewhere.

Just saw your last post. That seems pretty cheap for a starter. Don't think a starter shop would do much with that. I'd probably replace it. 

Then I'd probably find out that it was the solenoid after all lol.

Posted

Yeah, I kinda want to rule out the starter solenoid, but it looks like a very detailed job to get to that, as well as the ignition switch.  But if I manage to get to both of them, how do I go about testing them?

Posted

as far as the solenoid, just make sure you've got the same voltage on both sides, you ought to be okay..The two times i listed above, i had 12.5 on Batt side, and about 9.8 on the other side.  I don't know how it does it, but it did a new solenoid fixed it.

As to the solenoid, you wouldn't need to test it directly at the solenoid. There's a perfectly good cable already attached to the lugs on either side of the solenoid. Check it on the other ends of the cables. In a no start situation, you might need to access the solenoid directly. But not this time. 

Checking the switch is a bit more involved, but only because there's at least three positions, and usually more. But for your issue, there's no reason to check to make sure the off, or on works. It'd be more about resistance, and checking for corrosion. Sometimes corrosion happens internally, like when you wash it, and get water in the keyhole. Over time, this can cause problems. 

Checking it is a very simple procedure. You just test each position, one at a time. Unfortunately this is probably best done with direct access. 

I wouldn't spend a lot of time on it. If the starter is getting what it needs. Then we know everything else is working.

well, it may be hard to get a accurate reading  since you will need to be cranking the engine for that side to get powered up. unless  you disconnect the cable  at the starter and risk sparks and shorting something out.

The starter is out, but if I can get it checked at a different location, please let me know. I don't want any sparks! It's just a real PITA to get to the solenoid, as well as the ignition switch.

Wrap the test lead along with the terminal with electrical tape. So they're connected, or use some extra wire. You should be able to sit in the seat. Those leads are several feet long. 

Posted

Well, I can't sit in the seat. Had to remove the seat to access the starter. 

I figured if I kept everything insulated I would keep the sparks to a minimum. 

I don't have a service manual. Didn't want to pay $75.00, especially after seeing some posts from others who have purchased it and advised it wasn't worth the cost. 

The leads that I have with my multimeter are not heavy wire. They won't burn through, will they?

Posted

There's no reason why the wires would burn. There's no starter, and no amp draw, so there's no current. No reason for burning anything. With a bit of care, and some electrical tape. There shouldn't even be any sparks.

That sounds good. Sparks ain't my friend!

I will disassemble the starter tomorrow and see if I can find anything out of the ordinary. 

I have a set of wires with alligator clips. I'll use those. 

I really appreciate all your help, folks.

      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.

      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.

       I just picked up this project that I was told would crank, but not start.  This is what I’ve figured out so far….
      I installed a new battery and get all dash lights, head lights, and brake lights on when turning the ignition on.  Fuel pump even turns on.  It does not crank with the key, but would when I jumped the starter solenoid, so I replaced it…..no change.
      Figured I’d check for spark and compression while I was dorking around.  Compression is 150 psi, but there is no spark.  Replaced the spark plug… no change.
      So, is my new starter solenoid bad?  Could it be the brake or gear position switches even though the brakes and neutral lights come on?  Not sure where to go from here.

      I have an Axis 500 4x4 UTV that I was given.  It looks like an almost new machine with 39 hrs on it however it was apparently under water from the hurricane . I have no spark at the plug. I have replaced the plug, the plug wire, & the stator so far. Can anyone advise me of what i need to check and or replace to get this thing running? Any advise would be greatly appreciated. 
                                    Thank You,
