cucv voltage drop

[purediesel]

When i turn my lights, turn signals, or any thing light related on my volt gauge drop to 0. It does not seem to drop on alt. or batterys. Stays at 28v but lights and gauges in dash go crazy. Any help would be helpful. Everything underhood seems to read fine. I have ran all wiring diagrams. One alt is at 13.8 and other is 14.2 whille running. I am farily new to these trucks. It has new alts and batteries within a year.

Welcome to Steelsoldiers.

Have you taken out all the fuses, cleaned the connectors, tightened the connectors and installed new quailty fuses?

Also have you removed and cleaned the connectors on the instrument cluster?

This is an issue that seems to comes up weekly.

Do all listed above and check the ground wire bolted to the top of the parking brake pedal.
