Radio Ground Problems

Lately my radio has been shutting off randomly. It usually powers off for a second, then powers back on. Occasionally it will power off and not be able to be turned back on for 30 or more minutes. Occasionally it does not turn off when the truck is turned off, or come on when the truck turns on. Both the stock radio, and an aftermarket one that I installed is doing this.

 

 

I suspect it is a bad ground somewhere. I checked the wiring harness at the radio, it seems fine. Where else would I check the ground at? Where does it ground to the frame? Also, would aftermarket speakers cause this problem if there was a short in the speaker wiring somewhere? I don't think there is a short, but I'm trying to explore all of the potential reasons.

 

Thanks

It could be something in the radio itself. Could probably pick one up cheap with people constantly upgrading.

make sure your antenna cable is being plugged in properly to the deck and your antenna

 

I double checked where the antenna plugs in to the deck, that's OK. How do I access the bottom of the antenna mast to check there?

It isn't the radio, I replaced the stock radio with a Kenwood, the problem happens on both.

Sorry, missed that in your original post.

 

Ya, thats a tough one. I would say get a volt meter with a continuity tester and start poking around. It would be best to do it when the problem is going on obviously which is going to be the hardest part. If you have the radio out and have it produce the problem then check the harness as gently as possible to make sure you still have voltage going to the radio and check for shorts with the continuity meeter. That should at least tell you if it is a short or a bad harness. Check your wires coming off the harness to make sure nothing is frayed somewhere behind the dash because of rubbing against metal. When you had the Kenwood in, i assume it was plugged into the same harness with an wiring kit?

 

Check the fuse box to make sure everything is tight in there.

 

If you cant get it to do the problem at idle, have the radio bolted in with the screws exposed and keep a screw driver on you. When it does it when driving around pull over and take out the screws. See if the simple act of pulling out the radio fixes it. If it does then you at least know it is probably some going in behind it. If not you might have to start tracing wires under the dash.

 

Not a fun job but good luck.

      Transmission Temperature Hitting 220s

      Thanks, so being a different beast altogether, anyone know what the "optimal" temp is for the 10L80/90 for proper shifting?

      Some Assembly is Required

      How many years have I pointed out every point in that link to the folks here and been avalanched with criticisms and outright hostilities at times? I ran counter to even the great CUSTOMBOSS and Lake Speed Jr and the half dozen experts on YouTube and in the final.....GM, Physics (Stribeck) backs that Grumpy old Bear.    Honestly, I never said a thing engineering hadn't studied silly and laid in concrete during WWII. But I'm old, the information is old and yet, the Laws of Physics are eternal.    Okay there is one exception. I vehemently disagree with their use of the word 'tolerances' when what it meant is "clearance".   The clearance is the distance between two objects. The tolerance is the degree of acceptable variation permitted in that clearance. I.E., piston to bore clearance is 0.004" with a tolerance of +/- .0002" so the clearance is in specification if it lies between 0.0038" and 0.0042". Cutting that 'tolerance in half has ZERO impact on lubrication requirements. Makes for more difficulty in manufacturing.  But a tighter clearance 'MAY'. Depends on finish. Anyway....   It's one of those statements made by people to make themselves look smarter than they are to convince people who are as un-enlighten as they seem to manipulate their behaviors. But hey, the blind leading the blind puts them both in the pit.

      Gas Prices

      By Grumpy Bear · Posted

      Out and about yesterday on a long Saturday drive I passed a lot of Shell stations. My preferred, so I pay attention. Lot's of small town Illinois so not six stations in three blocks like the city.    Everyone of them over a radius of say 100 miles had regular at $4.19 but one which was the one closest to home at $4.15. However Premium pricing varied greatly between 85 cents over regular to $1.50 over. I'm not counting the price of the station with the lowest regular so the reference is the same for the remainder and all within the same brand. However the spread discrepancy holds across all brands.     @txab, any thoughts on that?

      Future GMC Jimmy

      By revrnd · Posted

      What are your thoughts? The Chevy Blazer relaunch was an epic case of 'lunchbag letdown'. Jeep Wranglers and Ford Broncos stick out like a sore thumb.    The AI photos do not look like a 'retro version', but shrunken Tahoes. Get away from the 'futuristic look'. I've seen two concepts. One had rectangular headlight like a Rivian and the other way too big headlights (similar to a previous non-Wrangler SUV) should include dual round headlights like the early version.   If not this would look OK   At least it has GM styling (albeit the K2XX) A lot of the images floating around look like Bronco IIs or the current Bronco. Looking at the Broncos in my area (central Ontario, it seems to be a mix of 2 doors and 4 doors, 'mall rated' to ones that could go offroad.    I'm sure a AT4 and AT4X RPOs could be outfitted similar to a Rubicon if the braintrust understood the whole offroad scene. Crossing my fingers that if it does see the light that the front air dam/bumper doesn't extend below the center line of the tire...

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well
