With engine running, Amp meter is always on charging side, even when Optima battery is fully charged. Otherwise, dash amp meter responds correctly when load is increased and or engine idle is increased. Checked running voltage which is continually fluctuating from less than 1 volt to as high as 9 volts. This doesn't seem right to me? Disconnected armature and field leads then even the battery lead from the regulator but this didn't solve the problem? Any ideas on what I could try next?
Thanks
