Generator Test (Overcharged Battery Check)
WARNING: This page is about a different car, the 2008 Suzuki Grand Vitara, 2007 Suzuki Grand Vitara, and 2006 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.
- To determine battery condition, refer to BATTERY DESCRIPTION .
- If obvious overcharge condition exists as evidenced by excessive spewing of electrolyte, measure generator "B" terminal voltage at engine 2000 RPM.
- If measured voltage is higher than upper limit value, proceed to GENERATOR DISASSEMBLY AND ASSEMBLY .
- Check ground of brushes. If brushes are not grounded, replace IC regulator. Then check field coil for grounds and shorts, referring to GENERATOR INSPECTION .
