help my electrical problem

Ive got a yamaha bullfrog 200, (1980s ish) its got no pullstart so i rely on the battery (new) which keeps going flat even when the bike is running. I use the bike at night with its lights for hunting and battery can go flat in a couple of hours even when running. I must have an earth leak somewhere but don't know where to start looking of which wire. Maybe someone has an idea where to start looking, thanks heaps.

Bullfrog, make sure batt is fully charged, start engine and with a digital voltmeter check the voltage at idle and at 1/2 throttle. Should be 13.5 to 14 volts. if it is, turn on lites. Check voltage at idle and 1/2 throttle. If it drops below 13 v at 1/2 throttle, your lites are drawing too much current or the charging system has a problem.
Hope this helps,
