Overcharged Battery

1. To determine battery condition, refer to BATTERY.
2. If obvious overcharge condition exists as evidenced by excessive spewing of electrolyte, measure generator B terminal voltage at engine 2000 rpm.
3. If measured voltage is higher than upper limit value, proceed to disassembly of generator service.
4. Check ground of brushes. If brushes are not grounded, replace IC regulator. Then check field coil for grounds and shorts.
