My buggy (with a 1500cc motor) turns over very slowly, and hasn't turned over fast enough to start the engine on its own. I've push started it several times, and let it idle in an attempt to charge the battery, but no luck. I put a voltmeter on the battery leads and it reads right on 6 volts at rest. However, when we go to crank the motor, the voltage jumps way down to around 2.5-3.0 volts. Is this normal? Do most batteries lose that much voltage during starting? Should the voltage stay the same? Is this a sign that the battery is shot? The battery looks fairly new, and is an Interstate battery. Any help would be apprecaited. Thanks.
