Hey T. As Peter suggested previously, try the radio(s) in your other BLT to see if it works there.

The radio is from my other T-type.

I would still suggest you try the radio back in that other BLT. It is possible something fried the radio on your current BLT with the radio problem??? By trying it back in your original BLT it will tell us if the radio is still good. It may have been a bad cable/antenae and it has blown something in the radio.

This is a strange issue. It seems 1 + 1 does not add up to 2.

Hey T,
Assuming it is not the radio, you have eliminated the antenna and it's cabling and already checked the +voltage at the radio connector - the only thing I can come up with would be to try running a temporary ground wire from the metal case of the radio to a good ground point in the car. I am sure you know a flaky ground will do some pretty strange things in a car.

Oh, is the wiring harness stock or has it been modified for a different radio? If it has I would go over that for sure.

Thanks - Peter

I'm just curious, did you ever solve this; it's an interesting problem.

i had the same problem with my t when i got it. stations would act like they would fade out to static. took it to a audio shop cause i got tired of trouble shooting it and it was something to do with the antenna and a bad ground.

:mtt: :stt: sounds like you either have ac generation seeping past the diodes in the alt (replace it) or poor power/ground connection. do a voltage drop on both wires at radio and also check with dvom for ac current's presence good luck

OK, I'm still having the this problem and it has gotten really old. At some point I found that if I pulled the radio out and shoved it back in, the problem would be temporarily solved so I haven't done much about it. I did test the wires again yesterday. 0 ohms to the ground wire. 12.5 volts to the power wire with engine off. I did not test the two other power wires but will do so again. I cleaned the battery cables and engine ground a few weeks back.

Anyone have any other ideas? Should the case have 0ohms to ground when the wires are plugged in?

Yes the case to ground is supposed to have 0 ohms as it is all linked to ground.

Well just an update on this old, annoying problem. I rewired the ground, but still no good. Voltage measures 14.5 volts, and I never see the car's voltmeter move when the problem happens.

Well I checked all the wires, nothing out of the ordinary. Then I tried putting the radio back in my 87 and hooking it up, it doesn't work there either. So now I'm out two car stereos and I don't dare put another one in. What should I do? Is this repairable?

That is so strange T. I am also confused by what is happening. Maybe your car needs an exorcist? I wish I had more ideas for you though.

have you tried an aftermarket radio? i know this sounds bad and i wouldnt suggest doing it but for some crazy reason my factory radio did the same thing...and as weird as it is i smacked the dash once(out of frustration at first) and it instantly came back into the station. it worked like that(where all i had to do was whack the dash above the radio) for about a year. i know of a friend who has a 88 park ave. that does the same thing and that worked in his too...weird i know but when i took mine and had it worked on they told me it was a ground problem but also installed an aftermarket head unit. could have been feeding me a load of crap but i never had the problem after that.

Well I picked up a stereo at a yard for $20, we'll see how long it lasts. The guy there used to run a stereo place in the 80s, he said that problem was quite common and was caused by battery cables being loose to played with. I did have a problem last summer with my battery cables so I'll give it a try.

Anyone have a T-type stereo for sale?

After trying it out, I found that the radio I got is setup for Steering wheel controls(91 Bonne) so I can't use it.
