1984-1989 Corvette Digital Cluster Bench Test Power Cable v2 1989Bench Test Power Cable This bench test power cable is a great way to power up the cluster while it's outside of the car. It's a great way to determine if the problem is with the cluster or with the car wiring, and to test the repairs you've made to the cluster. The cable provides 12V power and ground to the cluster. It allows for testing of the basic functions of the cluster (backlighting, dimmer, power supply, LCD segments, turn signals, high beam
LCD Driver ICs are circled in yellow in the image above
shorted transformers and broken traces are all possible in the 25+ year old power supply
The 1989 Power Supply is integrated onto the motherboard
and therefore the color around the black information
We recommend replacing both
but the display is very dim
After Restoration - When the cluster is on
then the Xenon bulb Kit we sell is probably a better choice
Note: These are factory OEM used parts
and Gold plated board and mounting pins for maximum life
and they consume 65% less power than the factory bulbs
