My truck died one day on the road after the battery light came on, then all my dash displays went blank and the truck died. I charged the battery and I was able to drive it for 2 days and it did it again. I replaced the battery and it lasted 3 days and it left me on the side of the road. I charged the battery up and took it into the shop where they tested the battery and alternator, both of which tested good. I took it to a second shop and had them run a test and both were good. Today as i was driving the ABS light came on and the dash went blank, but the truck did not quit. The dash came back on and I made it home. Has anyone had this happen and what was the fix? I checked all the fuses and made sure they were seated firm. I'm lost here.
Sounds like a intermittent alternator problem. If you have access to a volt meter and can connect to a Power Point plug in the vehicle watching the voltage might help.
Have you checked the power distribution box under the hood near the battery? Have you checked the ground cable from the battery tightness? If you have a relay on the way out, or loose in the connections, it could drop power intermittently. I'd check the relays under the hood in the PDB.

Earlier this week the girlfriend stated while driving she would notice all the lights in the instrument cluster would light up and the gauges would drop to zero. This would happen for several seconds and return to normal. I have driven it a couple times since then and sure enough, intermittently this happens. At that point there is no other condition. The car is still running and driving fine while this is happening.
I haven't had a chance to look into it so she kept driving it.
Now after a few days of this happening she is experiencing it not starting from time to time. She says it'll start one time as normal and then next time she goes to start it she turns the key and nothing. She says she usually can get it started after the second or third try and when it finally starts it starts like there is no problem at all.
Sounds about the same?
Checked the battery terminals, they're good. Where would the ground be? I can only assume there are a multitude of ground connections which could be loose.
I checked the battery voltage. In the morning, after it sat for more than 24 hours it read around 12.2 volts. After starting it and while running it reads around 14.6 volts. When I turn as many accessories on as I can it still reads around 14.6. Seemed pretty good to me but I took it to my buddy's house and he put his tester on it too. When I got there we put the tester on it while off, it read about 12.6. We then started it and while running it read, again about 14.6. He then put a load on it (his tester has this ability) and it stayed right there.
The battery and charging system seem to be fine.
I have been driving it a bit lately and have noticed, when all the dash lights go on and the gauges drop, I can give the dash a tap and it instantly goes back to normal. I have also noticed, when it doesn't start I can turn the key back to off, give the dash a tap and try it again and it starts right up.
Seems to be some sort of loose connection in the dash somewhere. Anybody know of a connection or condition in the dash that could cause the car to not only have the lights and gauges act up but the car not to start?
