2008 Suzuki LTR 450 wont start :(

2008 suzuki ltr 450 will only start when i have the battery charger on it, and then the quad turns off when i take the charger off.

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.

Glad you got it fixed, good call Bot.

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