Electric System Question

Sounds normal to me. A freind of mine had trouble with his regulator,it ended up being the plug in to the regulator was broken.

Regulator is brand new. Is it normal for output to decrease as rpms increase? The manual says it should be putting out over 15 v @ 5000 rpm.

As long as its charging above 13 volt your safe.

You should have 13 volts at idle and it should increase as you advance the throttle. Thats the way my Foreman and the wifes Rancher works.

You should have around 13 volts at idle and it should increase to a little over 14 volts as you advance the throttle. Thats the way my Foreman and the wifes Rancher works.

how old is your battery and what kind of shape is it in?

Battery is new and fully charged. Voltage is dropping 1-1.5 volts as I increase off of idle.

If the battery is in good shape, it may be that the regulator is cutting back on the charge because the battery is full. Try disconnecting the spark plug, or other wise disabeling the Ignition, and crank the motor for 15 or 20 seconds. Check the battery voltage then and establish a base line. Then start it up and check the charging system again. The voltage should increase to about 2 volts over the baseline battery voltage after you crank it. As the charge builds up the charging system shold cut back to avoid overcharging the battery.
