American SportWorks LM650 starting problems.

Recommended Posts

American SportWorks LM 650 won’t start at times. Starter won’t engage the solenoid just “clicks” much like a weak battery would cause. Battery was replaced and problem went away and then came back. Replaced positive battery terminal. Problem resolved then returned. Replaced negative battery terminal. Problem gone then returned. Replaced the positive and negative battery cable ends. Problem resolved and now returned. The repair lasts for maybe 12 starts, then the solenoid just “clicks” again as it will with a weak battery. So I replaced the ignition switch. Problem solved for a week. With each “fix” the problem is resolved but only temporarily. Does anyone have any suggestions ? To replace the starter is expensive especially if it’s not the problem.

@Travis Bad starter on an American LandMaster 650. “Finally “ found a starter. Subaru is out of the small engine business and replacement engine parts are scarce and expensive. Anyone ever  change a starter on an LM650? Can’t get on top mounting bolt. The service manual is no help and neither are shops in the area. Don’t want to just start removing hardware if it’s not necessary.

Installed the new starter on my LM650 with the Subaru engine. Removal was simple once the voltage regulator was removed. The starter would not engage all the time. Symptoms of a bad solenoid or bad starter. Subaru no longer is in the small engine business so locating a new started was difficult and expensive.  To my dismay, the new starter reacted the same. Here’s what I’ve done so far...replaced the ignition switch, the battery, the Battery cable ends, the battery post terminals, and now the starter with solenoid. I’ve cleaned or replaced any wire terminal dealing with the starter, ignition switch and battery. I have run out of ideas. The Subaru help line suggested the starter relay but that is part of the starter and the new starter covered that. The voltage regulator is the only thing not yet replaced but the dashboard digital volt meter indicates that it is working. Max voltage output is 14.25 volts and when the lights are turned on it drops to 12.5 volts. Does anyone have any suggestions ?

Yes, it has a neutral safety switch. If the Vehicle is not in neutral, the ignition is completely dead. My problem is not That. The starter attempts to engage the flywheel but cannot. It seems like it cannot roll the engine over. After several attempts it will succeed and the motor starts. As I stated previously, additional amps were applied and the starter engaged each time. The battery is brand new and charged. 450CCA capacity.

Old post but, I would have tried a valve adjustment. Controls  the decompression when starting allowing it t o turn over. Depending on where engine stops, it could be hard to turn over.

      Sector E1 12v battery. Just been doing a Li ion conversion on a customers E1, and with the old pack disconnected (DC to DC runs all the while with pack connected) the 12v battery was showing 4v. Its worth shutting off the main pack occasionally (big red button near your right leg on UK spec machines)  and checking the 12v battery. Once the pack is off measure the 12v battery with a multimeter, its under the opening beneath the drivers seat behind the drivers legs. . Its important if you use the winch, as the DC to DC isnt man enough on its own to power the winch under load. Its important for me as I need a decent 12v supply to run the Electronics on the conversion. The battery is a YTX20L-BS

      So i have a 2011 EFI 700. the SxS will crank right up everytime without any issues. If i let it run or ride it for about 10 mins it will shut off and then it may turn on if i am lucky but most time i have to let it sit for like 3 hours and then it will run again. i have done the following
      -New fuel filter
      -New injector
      -New spark plug
      -New coil pack and plug wire
      -New air filter
      Also could i get a grizzly 660 engine and put in it or would it not work.

      Very new to any forum. Haha We have an 09 R2 joyner renegade 800cc. We are unable to start it. It has been sitting for a few seasons. It has spark(new plugs), it get gas, fuel pump works(new), fan comes on on initial key turn, sounds like system doing its check. It's turning over but nothing.  Clean fuel, gas tank cleaned, fuel going through all the lines. Relays and fuses checked and pulled and reseated. New battery even. Thanks yall.

      2019 Coleman Outfitter 550, 160-ish hours. Was driving it slowly and it just slowed down and died. Won't start. Pops once as soon as I start cranking and that's it. I have great blue white spark on the spark tester, jumps 1/2". Changed injector, no joy. Changed plugs to new several times, no joy. Pulled injector power wire and tried ether through air intake after removing air filters- nothing! I do notice if I put my hand over the air intake where the filter goes, I get pressure  pushing back at me. Jumped time? Stuck valve? Is there a decompressor on this that could be malfunc?
      This is the one I've had that was inop for months and months while Coleman tried to find someone to fix it. Warranty is long expired now. I'll never have anything good to say about this thing.

      I will do my best to describe this so bear with me. The UTV is a Trail Wagon (American Sportsman) but the make might be immaterial with this problem. I have now gone through three batteries in a few months and the last two just a week apart. Here is the sequence:
      I use my utv lightly almost every day but that is only about 5 months a year as I live in Florida and Michigan and the utv stays in Michigan over the winter. I always store the unit and trickle charge the battery, and this does not seem to be the issue - let me explain. Last fall, just before I left for Florida, the  battery died and it was a few years old so I wasn't concerned. It did die without a lot of warning as I didn't get the gradual slowing of the start process that usually precedes the battery death, but I didn't think much about it. It died completely and would not take a charge or a jump so I bought a new battery and it worked great. I only drove it once or twice and then put it up and left for Florida. Came back a few weeks ago and the battery was in good shape on the trickle charger. Put it in and everything went well...for about a week. Without warning the battery went dead (10.8V) and would not take a jump or charge. Like the previous year there was no gradual wearing down, it just quit. I chalked it up to a cheap battery and got another battery. This one was strong and the utv started up like always...for about a week. Same thing with no warning and this time the battery was at 11.4V. I'm thinking bad alternator/rectifier, at that time but I needed to check it. I charged it, though it again did not seem to want to charge, at first, but then I got it to 12.6V so I gave it a shot. The minute I turned the key it died - no starter sound at all. I jumped it with my tractor and it started. I immediately put a voltmeter on it while it was running and it was up around 14.4V which tells me the alternator part seems to be working. I let it run for a bit and shut if off. Next morning...dead (11.4V) and struggled to take a charge but I did get it to 12.6V again so I went to hook it up. Put the positive cable on first and just for kicks I checked the voltage before I hooked up the negative cable and it was 11.3V - just from hooking up the positive. I got another older battery to take enough of a charge (12.8V) to try it again. This time I hooked up the negative first and checked the voltage - 12.8V still. Hooked up the positive and checked the voltage - 10.8V. This makes no sense. Simply connecting the positive cable completely kills the battery without ever turning the key or anything. And when it kills the battery it really kills it. They usually don't want to take a charge so something is really busting them.
      I am at a loss...thoughts?

      Hi All,
      I picked up an old beat up 2010 American Sportworks Bull Dog 300 BD300.  I would like to restore her...  Does anyone know a good source for parts other than the OEM?  I find $130 for brake pads is kind of unreasonable... I also need a steering rack and other things... I took apart the steering rack and it needs a new bearing and oil seal... Of course the OEM only sells the complete rack for over $200..  I found the correct bearing for $6.00. I am having trouble finding the correct oil seal.. 
      Anyone that has info on one of these machines, please chime in...  I am used to the ease of finding info on Polaris, Honda, Can Am, Kawasaki, etc.....,  Info and parts on these seems to be scarce..  Some of the parts on it look like Golf Cart parts as well as some look like Go Kart parts..

      I have  a bulldog i bought from home depot in 2013.  In the last season it started refusing to shift from neutral to either forward or reverse.  I changed the trans axle fluid and made sure the cables were lubricated and free.  With a lot of coaxing, I can sometimes get it to shift.  once I start driving it, things improve until I let it set awhile.   Any suggestion on where to go from here?

      I've got a trail master sxs by American Sportworks and they will not sell me a basic gas shock for the front strut.
      The shock is a straight forward 1 1/2" diameter tube.  
      Where can i buy just the shock? The shock and strut together are $350 US OUCH!!!!

      Not too long ago someone posted on a good place to buy American Landmaster (Sportworks) parts and now I can’t find it. Any help would be appreciated.
