Power Supply Repair Kit (1989)

Click Here for 84-88 Kit

 

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 kit provides the parts commonly needed to refurbish your power supply.

 

The 1989 Power Supply is integrated onto the motherboard, and is not replaceable!

 

The power supply on the 1989 model is not a separate board - it is integrated onto the motherboard of the cluster. Therefore, it cannot be replaced with an aftermarket power supply. When it fails, it must be repaired.

 

Signs your Power Supply may be defective

  • When the ignition is on, the cluster remains dark and the info can't be seen

  • Segments randomly flash on the dark LCD panels

  • The LCD or CLSTR fuses blow repeatedly

  • Physical damage to the components of the power supply
