So, a funny thing happened in the Bronco yesterday to and from work. As I am pulling out from the house to head to work, I notice the gauges in my dash are not working. Fuel level, oil pressure, everything. Turn signal indicators were also not coming on. I jiggle the key a little bit and they come back on, but over the course of the drive they continue to lose signal and regain it. Fuel level was at/below 1/4 tank during this. After work, I prudently decide to stop off and fill the tank up. 12.82 gallons later, I'm back on the road with ZERO issues in the gauges. 15 miles later I'm at home and I have noticed no issues whatsoever.

Now, since I did the rewire earlier this year, I have noticed no issue with any of the gauges. However, during that time I have never let the tank get below 1/2 tank. Yesterday was the first time. My initial inclinations are a bad ignition switch causing a lack of continuity in the system, hence the jiggling of the key solving the problem. But I'm curious. Think there is any way a bad/going bad sending unit could cause the entire gauge cluster to lose all signals? Maybe a bad ground? Resistance getting too high as the tank level lowers?

Thoughts?

You have my vote on the ignition switch or a bad ground. Can you jiggle the keys to make the gauges go dark again?

It's the switch. A bad ground can not cause those symtoms.

I have to jiggle a lot of things to make them work.

Remember mine Zac? I was having intermittent power and it was you that told me the switch after I looked everywhere. I'm gonna vote switch too.

Yeah. Your Bronco gave my Bronco the cooties. Thanks. Seems like as fine a time as any for me to get that F150 switch with the dual sided keys installed.
