Well, I really don’t have a bench with a decent 12V power supply, etc on which to implement your suggestion.
Anyway, as per usual, it had a broken antenna. Taaiyo figured it was a clamping diode for static porpoises, and it makes sense as to what the symptom is if it shorted. Again, thanks for all the info, and I will post back to this list when I finally get offa my unemployed butt and fix this puppy!
Spark Gap Source or Replacement
I have the C radio. Other than the audio signals to the amp, what other stuff goes over to the amp from that radio? The two bands use that transmission line differently if it isn’t balanced. I have no idea if the original poster 9 years ago!! I tried several things but radio repairs folks were too quick to simply sell me a new radio. Sometimes mere pinout will stop someone in their tracks no pun intended. Powered by Denizen – Custom Software for volvo Enthusiasts. Ones I’ve fixed in Volvos seem to be Mitsubishi.
But, on that same subject, what would you recommend as to specs for tqiyo replacement that Wg20 bust? After reading your message and also the archived posts concerning the radio problem, I raiyo in agreement with you that the failure must be inside the radio or antenna connection at the radio.
Maybe at work, where you embed?
Failed shorted A fifty cent part. Also MGB and some old motorcycles.
It took a lot of time and fiddling – electronics is not my forte – but was a fun project and felt good to recycle the old “Volvo” amp Good question about how the shorted diode might affect both bands, and I admit no ga20 telling me otherwise; just something I read that resonated with experience.
Art, First, to correct my previous post: Near the back right corner is a very taiy circuit board of sorts about 2 cm Deep x 1cm High x.

I have a T. However, the FM is dead-silent.
You’re right yaiyo, poor choice for analogy. Thanks for the info! From the schematic symbol silk screened on the circuit board it is a switching diode pair. Regardless of the cause, I placed a folded up old credit card between the board and metal surrounded card assy and the radio now works. As I recall, this was a common trouble caused by a simple clamping diode designed to drain static charges acquired by the antenna mast at 60 mph in most all auto radio designs.

I’ll post any findings back into this thread. Or am I demonstrating my general lack of RF design knowledge? Anyway, I saw your post, and thought “Aha! But given that same information, I wouldn’t be so sure.
With some laborious and careful amateur soldering I was able to attach female RCA jacks to the amp’s input wiring. To complicate matters, the Volvo radio doesn’t have any “speaker” outputs, per se; so I’d have to rig up an amp, blah, blah. One day, his supply of the birds ran out so he had to go out and trap some more. Plug and play culture nowadays.
The back PWB is darker around this area and looks like it suffers from a heat issue. I just can’t imagine working in the front seat of the car, referring to the schematic we don’t have to find parts on the circuit board. The spark plug pulses suppress the gain control circuits and the radio won’t work well on the road without this diode package.
This led me to believe it was not the antenna, but rather something in the radio. Thu Oct 23 Any thoughts on that?
I have a 95 which also has had frequent FM failings. I mean, it would seem that you’d want the clamp to be RIGHT after the antenna before any “splitter” arrangement. Is that an Alpine or Blaupunkt radio or something completely different? Cassette worked fine with my iPod cassette adapter.
I don’t believe exotic parts were being used in auto radios.
I do not think it is because of anything shorting out but because of some solder pads that are broken. Gently touching this thing would cause a complete lose of FM signal. I found some info here about the pin functions of the amp’s DIN connector – also removed the amp’s case to have a look at the circuitry and confirm.
