I would guess that your stator or regulator/rectifier is bad or there is a connection problem somewhere, check all electrical plugs and wires for loose fit or damage. It seems like the battery isn't holding a charge either, first thing I would do is have the battery tested. I would also check the voltage coming from the regulator/rectifier to the battery, this will be DC current. You will need to disconnect the wire from the battery when testing it. If it is low or none, then I would check the voltage coming from the stator, this will be AC current, so you will need to set your multimeter to AC voltage. If you don't have a multimeter, I would get one, they aren't too expensive and they are a must for tracking down electrical problems. Testing both, the stator output and regulator/rectifier will need to be done with the engine running. If the stator puts out no power, then that is probably the problem. If the stator does put out power, but you get no voltave from the regulator/rectifier, then the regulator/rectifier is the problem. This is ofcourse assuming that all connections are sound. Connection between to points can be tested with the multimeter too, use the continuity or resistance setting. Resistance should be next to nothing if there is a good connection.

My friends LTR did the same thing. Is that the original battery? If the battery doesn't hold max charge there is not enough juice to run the fuel pump.

yup that's exactly what it was! thanks!

and thank you for writing all that stuff...future problems might bring this up haha.

You bet, but for the record, I did say in there that the first thing I would do is have the battery tested.

      posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
      -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
      -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
      -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
      -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
      -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
      -I THINK it has a mikuni model x carb - diaphragm is ID 26mm  OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
      -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
      -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

      Does anyone know what the 3rd item is behind the battery on this ATV ? I know 1 is the,  solenoid1 is the CDI box, what is the 3rd.

      I need to figure out how to clean/fix or replace my neutral switch assembly On my 2008 Yamaha big bear 400 as generally the neutral light doesn’t come on when it is in neutral. To get it to come on I have to wiggle the foot shifter and hold it in just the right spot.
      I have googled it and can’t find much on the 400’s. I can’t find a service manual online and the parts manual is super vague.
      I think it is in the right side engine cover area, but not certain. 
       Any help would be great. thanks

      Hello again guys ,. I have a Quadmaster that has a very bad lean to my passenger side wheel. I replaced the a arm bushings with no change in the lean,  I see no bent parts and no adjustments available. It's always been there since I got it but became really noticeable when I put the lift kit on it. I'm going to add a picture of the problem if allowed.

      Working on a bayou 220 that has been ran extremely hard it's whole life. Literally had almost an inch thick dirt/oil covering the motor. Yeah that bad. Surprisingly it runs though. I cleaned the carb and tank multiple times. They're clean enough to eat off of. Readjusted valve lash and set timing. Was about 3 teeth off. It cranks good and runs good only problem is I have to cover the carb intake basically choking the hell out of it for it to start. The com choke works fine. It does this each time I start it regardless of temperature both ambient or motor. Wth? Compression is at 115psi I get 130s if I put a little oil in the piston chamber. Please help. Thanks
