New Power Supply (1984-88)

New Replacement Power Supplies

The internal power supply in the Digital Cluster is a common source of problem with the Digital Cluster. Electrolytic capacitors dry out then short, the switching transistor leads break internally, and failed alternators and 24V jump starts can cause overvoltage which destroys the Varistor. This is a completely redesigned, NEW, modern power supply which is an exact replacement for the factory power supply.
