Hi all :-) Ok, I have been reading through this thread and I have a question. I am not new to wings. This one is my 6th one and it is a 1994 gl 1500 SE. with only 42,000 miles on it.I have had 2 1100's a 1200 a 1993 asp. and I have a 2002 1800 and now this 1994 SE with a side car. So my question is, In my manual it says there is a radio jack type pigtail for audio input but from what I am reading here it was only on the interstate, is that true? I have been looking for it and it is not there. However there is a two wired , green connector, with a white cap on it. What is that connector for. Could this be the plug in for that pigtail ??? And if so there was a part number listed somewhere in here for that pigtail.. I can hope can't I...... :-)
There is not any OEM aux input on your bike. You can build it by yourself.

Dang !! would you happen to know what that green connector is under the left pocket ? i had a complete factory manual for my 93 aspy but I sold it with the bike when I bought the 1800. never thought I'd own another 1500. But this one was to good a deal to pass up. Besides, I really like the 1500.

hey, both of your bikes are the same color...... you need to paint one. Hahaha 8-)

Can you add a picture of that connector you are asking? Are you sure it is not for the side marker light. The side marker lights have 2pin green connectors on both sides.

Thanks for getting back to me. I will go and look today. That green connector had a white plastic cap over it and it was tapped to the big wire harness.

If you are asking it to verify whether it is an aux input, as we know an aux input should have 3 pins for a stereo system, so it can not be an aux input.

Nope, that is not what I was asking. I started out by asking if there was an aux input on the SE as I could not find one. The only thing I could find under that left side pocket was the green connector with the white cap on it and was wondering what it was and hoping that it might be the aux. input connector without the pigtail on it. I went out there today and checked with a volt meter and there is 12 volts there when the key is on and dead when I turn the key off. So like what was mentioned earlier it must be for the side marker orange lites which this SE does not have.
seems to me that the top of the line model for that year would have all the belles and whistles and then the aspy and the interstate would have less. My 93 aspy had side marker lites......

The side marker lights like the saddlebag side lights, were after-market additions. Though the wires were there for the front marker lights, there were no bulbs installed. And the saddlebags had no lights or wires, they were only reflectors. It was the same for the SE as well as the Aspencade.

Hi Mike. Thanks for that info. My 1993 Aspy. that I sold about 6 years ago or so had side marker lites and saddle bag lites as well, so I guess they were installed by the PO before I bought the bike and this I did not realize. :-)

Great thread, an oldie but a goodie. I'm wondering if this will work for my '94 GL1500 Aspencade? What are the chances that the circuit board layout will have been changed? I don't want to remove the radio unit only to discover that the mentioned solder points have changed. Thanks, Andy
I think they remained consistent throughout the lifecycle of the GL1500.
Thanks for the reply. I'm just waiting for a quiet few hours to take the radio unit out and explore... 8-)

So you can do this mod if you want to but I would like to share with you a easier and just as effective solution. Go to Walmart or Online and buy the 14 dollar bluetooth audio cassette adapter from Black Web. It will connect to your phone or ipod and then go in your cassette player and Voila. Problem solved. Works like a charm, good sound quality, charge lasts all day.

Hi Folks, I have a 98 build and I did install AUX input on radio, following the fisrt image, but it got a very noisy in AUX . The cassete deck and AM\FM radios, continue with good sond.
I removed and weld again, but continue the noise
Someone can help me?

Thanks

Did you install (or connect) a ground loop isolator in between your audio source and the radio? If not, that's your problem. The radio aux input is very sensitive to noise, as it is a low level signal. When I installed my aux input, I actually built a ground loop isolator out of a set of audio transformers and built it into the radio.

I suspect the wires are melted and shorting due to overheating during soldering.

And I can't see the ground clearly from the picture. Can you add a better picture?

For the ground loop isolator you can find a product like below.

Hi, I did only install the cable in the board, I did not know about this product.

Possibly leaves the noise without it?

Follow another picture

Thanks for the helps

Ground loop isolator is necessary if you have a humming noise in the background.

For the soldering work you have done, I can say you haven't done a clean job. All the soldering residue should be cleaned off.

The wires should not touch the other solder joints or parts nearby.

Check your work again.

Ok Erdeniz, I'll buy the grounding loop isolator first and I will check the work again.
I'll say it later. :)

The ground loop isolator is really essential for this input, or you WILL have ground loop noise. As I mentioned, when I installed this into my radio, I used a couple of audio transformers and built them right into the radio as part of the input circuitry to perform as a built-in ground loop isolator.

Is that just plug and play on cable?

I have a hard time finding here.

Sorry for the crude drawing, I drew this on my phone. It's basically two audio transformers. If the transformers have a center tap, the center tape remains unconnected and unused.

The Left and Right inputs (along with their ground) are connected to one side of each transformer, and the outputs are connected to the other side. This way, the audio signal is transferred magnetically from the input to the output, with no actual electrical connection (which is what causes the ground loop).

Your drawing is perfect, I understand now. The audio transformer has some specs to find them ? Does it fit all components inside the radio?

I am sure you can find the product easily in your country, everything comes from China nowadays.

If you can't find, try Aliexpress there are many products for 3-5 USD with free shipping.

I placed it inside the unit easily. It is around 5-7.5 cm in length.

I searched only on e-commerce of the here but don't find.. In the amazon, Aliexress have but takes a long time the shipping, 2 to 3 month , I'm going to buy, and while I'm waiting, I'm going to build one.

If you choose China registered air mail you can receive it in 7-21 days. The customer protection time is 60 days, if you can't receive it in 60 days you can request refund. I have bought maybe 300 products so far and %60 of them arrived in less than 21 days. Maybe 5% of them took more then 45 days.

Of course I am talking about my country, your experience may be different.

Edit: I just checked my orders and saw that I received this product in 12 days for 7USD including shipping cost.
