battery is being drained as it operates and not taking charge

check tightness and clean both terminals and cables

how old is the battery
may have a dead cell ..wont take charge

check the charging input to the battery with a volt meter
has to be above 12 volts
if lower or equal to 12 volts ...no good
the charging stator inside the engine needs testing or repair or replace

stator is another word for an alternator or a generator


why it plays up
best guess the ATV if a 12 volts system wont run on 11 volts

Chances are your starter is out, get a replacement.

Your starter is probably out, or not properly connected. Locate the starter and there should be two wires going to it, they both should be marked with + and - make sure red goes to positive and black to -
If you want to test your starter before buying a new one, take it off of the fourwheeler, and hook it up to the battery. (note: this is not recommended by the manufacturer may void warranty. If you do do it.... Hold on to that starter.)

Fuel issue blocked jet maybe on the carb unlikely as new but sounds like a fuel starvation issue

thats a solenoid. might need to replace it now.

Bad battery

well if your wires fried then your battery was around 20v which means your voltage regulator was bad. you need to purchase a new one of those as well. as for the wiring diagram, if the wires around the battery had been fried. are they intact or completely burnt without you being able to locate to which each wire connects to?
