Why is my Doosan G60-SIIIA system undercharged?

An undercharged system in your Doosan Portable Generator may be due to a few reasons. If you've added accessories, they might be causing excessive electrical load; remove them or install a higher output alternator. Excessive engine idling can also lead to this issue; increase the engine RPM when a heavy electrical load is used. Inspect and clean any poor electrical connections on the battery, ground strap, starter, or alternator. The battery itself might be defective, so test it. Finally, the alternator could be defective, so test the charging system.
