Gauge cluster electrical problems - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Has anyone had this problem before?
Dolphin Gauges all work fine with headlights off. As soon as I turn headlights on all gauges stop working (go to zero or max). Is there a short or is it improperly grounded?
Truck is at the shop otherwise I'd take a video for a better reference.
Here's a pic of the setup. Not sure what PO did with wiring.

I could not agree more. The first thing to do is make sure everything is grounded correctly. If ground is not your issue then more information will be needed to help you.

Good luck,

I have the speed hut gauges in my truck. They work fine also with no lights. When the parking are headlights are on they max everything out but the voltage reading it stays the same. I figure it's a ground, but where? The orignal cluster didn't do this.

My gauges are plastic with a hot wire and a ground.

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
