I had the same problem. The dealer told me that i had a bad "rectifying regulator" (I thought it sounded made up). they replaced it for like $45 and i didn't have that problem anymore. if you have a dealer you can trust ask him about it.
If the Polaris 50 Scrambler only runs for about five seconds and shuts off, it could be a problem with the idle setting. This type of ATV has an adjustment screw on the carburetor for turning the idle up. This should fix the problem.
If the headlights flash on and off, there may be a problem with the bulbs or fuses. There may also be a problem with the battery connections or wiring.
1. You have a busted headlights. 2. You have a busted fuse for the headlight. 3. Have an Electrical wiring connection problem. 4. No battery charge
There is no fuse between the headlights and the battery. If the headlights are dead, then your problem comes down to: battery (may have some voltage, but no current) and the battery cables.
I'm not a mechanic / technician but if your battery is overcharging or the headlights are too bright so people are flashing their headlights at you when you are just using low beams ( it sounds like a voltage regulator problem )
Sounds like the battery went dead or you have loose/dirty battery connections.
Sounds like a dead battery. Try charging the battery, then start.
Because the power for your headlights is pulled from your battery. When the dashboard lights dim after turning on the headlights the dashboard lights aren't getting as much power as they were with the headlights off. With the motor running or off? The headlights draw a lot of current, but should not visibly affect other systems. There could be a problem with a worn out battery, an alternator that isn't charging correctly, or you have a bad earth between the battery and the chassis. Check the large cable connection between the battery (usually negative these days) and the bodywork, or between the engine block and the bodywork.
Sounds like an electrical problem, check your battery, alternator, and fuse box, and light wiring.
Problem with the charging system. Altenator, Battery, etc.. (may even be a loose belt causing the alternator not to spin fast enough to charge the battery).
a stock 96 scrambler 400 will do 80-110KM. ofcourse that depends on jetting, weather, runway. My 96 has been mod up, 40thou pistonpipe/clutches/shaved head/and of course polishings (inside and out). i have had long highway trips, it is easy to pass almost any thing. the problem is the steering is gone at 130KM to scary!! there is a cut and weld to correct that problem. now if you changed sprocket you could get up to 150-160KM/h.
Low oil pressure at idle. Can be idling to low, weak oil pump, defective oil pressure sending unit, or filter is not compatible. Change to another brand of filter and see if you still have the problem.
