AM Radio Stopped Working...Repairable?
I've got the radio out which wasn't too bad really even with A/C. I tested it and I've got power at the radio. It stopped working last week. No sound, no lights. Is there any complex troubleshooting or is it time for a "new" one off of eBay? I've seen a few period-correct AM radios on there. I'm tempted to get a look-alike digital FM that I've seen for sale but I think I'll keep the original look with another AM.
I did rip the center a/c vent duct but it looks like I can pick up some 2" at AutoZone unless anybody has a better supplier. http://www.autozone.com/autozone/acc...er=218605_0_0_ Thanks. ![]()

Re: AM Radio Stopped Working...Repairable?
The radios are repairable but you can probably get another AM radio cheaper then repairing yours.
I am currious as to how you tested the radio as you mentioned that the light did not come on. Did you check the bulb? Most AM radios that I have seen over the years work. They take a little time to warm up and the ground has to be good as well as the antenna. Around this area we only have one AM station! Jim

Re: AM Radio Stopped Working...Repairable?
I'm getting power to the red wire that is plugged into the radio. Radio is dead as dead can be. No lights, no clicking at all when I turn the knob to ON, nothing.

Re: AM Radio Stopped Working...Repairable?
These AM radios are always available on the parts board here for under $100.00 working condition with an excellent face. The most important thing to remember is to use an 8 ohm speaker. Any thing else will damage the radio.
You can check the speaker with a DVOM and make sure it is actually 8 ohm. If the speaker is original you have to consider that it is 40 + years old and they just don't have the shelf life. Contact Dave (DND Trucks) a member on here for a speaker if needed. You can buy an new 8 ohm speaker at radio shack for under $10.00 just to test. Make sure as JimKshortstep4x4 mentioned, you have a good ground. If the speaker is good, they will make noise even without an antenna.

Re: AM Radio Stopped Working...Repairable?

I'm with Jim. I'm betting it's the speaker instead of the radio. I know the radios die once in a while but in my experience it is usually the speaker. There are a couple of speaker options in this thread if you decide to go that way... http://67-72chevytrucks.com/vboard/s...d.php?t=589314 LockDoc

Re: AM Radio Stopped Working...Repairable?
So, the fact that I'm getting no light at the radio can still point to a faulty speaker? I can understand that not getting sound could be a bad speaker but it could cause no light too? Do all of my tests need to be done connected to a speaker even to test the light? I wouldn't think so. All I'm getting when I turn the knob to ON is quick "pop" at the speaker. No constant sound and no light on the radio face.

Re: AM Radio Stopped Working...Repairable?
Found a nice original AM for a great price from Bob Vidan out of Washington. Big Pontiac parts guy but he also has bunches of radios for sale. Nice guy to boot.

UPDATE: AM Radio Stopped Working...Repairable?
Quote:
Quick update guys: Got Bob's radio delivered today in record time from Washington state. Thanks, Bob! We're back in business with sound and the backlight. I'm buttoning things up now. I guess the old radio had been slowly dying because the new one sounds so much better. Kind of bittersweet that the old radio no longer works as I remember my grandpa cruising around listening to it for the past 40 years. I may have it repaired one of these days. For giggles, I pulled the speaker since I was already in there and it is stamped as 4 ohms? Everything I've read said these should be 8 ohm speakers? I pulled out my multimeter and sure enough, it is reading 3.9 - 4.0 ohms.

Re: AM Radio Stopped Working...Repairable?
Could be thats what did the radio in. if I remember right on the radio itself its stamped it has to be 8 0hms. if not correct it will takeout the power transister on the back.

Re: AM Radio Stopped Working...Repairable?
If I owned an am radio the only way I would know it wasn't working would be due to the lack of static noise.

Re: AM Radio Stopped Working...Repairable?
It worked for 41 years so I'm going to just leave it in there. I have a portable FM radio I listen to anyways. The AM if just for originality at shows.
