Speedway Motors GM CS-130 Style 220 Amp Alternator with V-Belt Pulley, Internally Regulated One-Wire Design for 1985-1993 GM Vehicles, High Output

The GM CS-130 Style 220 Amp Alternator has elicited mixed reactions from customers, particularly those who utilize it in their classic cars. While some users have found it to be a satisfactory solution for their charging needs, others have experienced significant issues shortly after installation. Feedback indicates that despite an adequate performance in terms of battery charging, users have faced problems with longevity, with one reviewer noting failure within a mere three months of moderate use. Those who have modified their vehicles for a higher electrical demand—such as electric fuel pumps and fans—have reported only moderate improvements in power output, with one user indicating that while it does charge the battery, it doesn’t provide the substantial energy burst they were hoping for. Moreover, there are concerns regarding the alternator’s functionality related to dashboard indicators, specifically the warning light circuit, which has led to some inconvenience. Although adjustments to idle speed have been made to accommodate performance needs, this has not addressed all customer satisfaction points, indicating a need for further development. In summary, the GM CS-130 alternator seems to work adequately for basic charging but has shortcomings in durability and certain features that might not meet everyone’s expectations in high-demand situations. **
