gl1500 low volume on the radio

Post by Ravyn » Fri Nov 02, 2018 5:04 pm



OK. I know this has been covered before as I have read every posting on the probable causes. And I mean every posting and there are a lot of them. Everything mentioned seems to be ok on my bike which is a 1994 gl1500 se. The tape deck does not work but it hasn't worked since I bought the bike and somewhere along the line the radio volume decided to not work. I have the radio and plastic piece that it is mounted to removed and the bottom metal panel removed. Everything looks clean and not disturbed, but I know that doesn't mean anything. Someone mentioned removing the tape deck wires or disconnecting them But I have no idea where they are. Keep in mind that wirering is not one one of my high points. hahaha And please keep in mind that I have read every one of the low volume post and checked everything mentioned unless I missed something ???

Thanks

Does your clock function correctly or it's reseting every time you turn the key off??
NO!, then check the #13 fuse (back up fuse) which is inside of the relay box, please don't ask me how I know :lol: :lol:

gipsy42. perhaps you could tell me which #13 fuse you are talking about ? If you are referring to one of the 5 amp fuses located in that relay box, well, as mentioned in my first post I have already checked all that. I just checked again to be sure and they are both ok. The only thing that doesn't function right is the tape deck and I sure as hell don't need it.
The one other thing I might mention is that the mute button lites up on the dash when I push it but it does not mute or lower the sound as it is already very low. ???? Before the radio decided to crap out that mute button worked the way it was supposed to work.
Got any other ideas ??

Is there any one else that wants to reply ? I just got done reading all 10 pages of low valume problems and they all say about the same thing.
I have checked all the suggestions and I have taken apart the mute switch and cleaned it and also jumped the wires together and no difference.

So, does the tape deck have anything to do with the radio volume ? Like with the door open or closed? There is no tape in the deck and it doesn't work anyway. Is there some way a problem with the tape deck could cause a low volume problem with stereo? Also what about the cb radio, it is turned off. I have taken the antennas off the bike as I do not use the radio. However the volume is low using my cell phone plumbed via the i-simple unit. I dis-connected the i-simple unit and still the same problem. Also I still get radio stations with out the antenna . But low volume. I hooked up the antenna and still the same problem.
I am about to take this piece of sheeet radio and throw it into the trash can and install a good after market radio if no one can help me !!!

Yes I think so. The diagram of the connectors looks like the ones on the radio. The bike is a 1994 gl1500se.

I'll look at all the signals that can affect the volume and post the tests to isolate the bike from the radio as the cause for low volume.

Ok.im looking at the intercom mute circuit.
I assume that there is volts on the mute line when the button is pushed?
The schematic indicates that the mute is activated when there's volts on either.

I am assuming you mean the mute button at the top cluster on the left handle bar.

Ok. If I mute by pushing in the mute button there is 4.5 volts at the blue wire and no volts at the green wire.
If I un-mute it, botton is out, there is no volts at either wire. That just doesn't make sense. The mute lites up on the dash when you push the button in like it is supposed to.

I'm at my big screen computer rather than my phone.Itwill be easier to review this.
The mute circuit from the button on the left cluster is working.Somethimg else has it muted.

While I try to sort through this can you check a couple of things...With the radio on...does the volume control have any change in volume..
Does turning the middle (intercom) have any affect..and is the intercom power control turned off(next left control).
Can you unplug the cb connector from the radio and check for changes.

Also..does your radio have a button (top right) marked "H-S" or headset speaker and when pushed does it show that indicator light up on the radio display lcd.?

In case your wondering...the cassette player does have a "mute" function..It happens when the tape changes direction..It is a switch on the head assembly this the comment of unplugging it..Here's a picture from the manual for it's location..It's the lower plug second from the right.A 5 wire plug..Unplug it to see if that part is causing the mute..You also loose the cassette adaptor function.

Nothing changes when I unplug the CB. and the motherboard or whatever you want to call it does not look like the picture you posted. is the tape deck five wire connector underneath this board. I will try to post a pic of my board

In your picture,the plug to pull is the white one on the lower left side of the main board..not the one with the blue wires in it.Just to the right of the large green plug.

I suppose you have also looked at the fader control.Mine was a incomplete add on and the control was not mounted..
If it has one.
Keep in mind..I'm going by a printed schematic and repair manual and not hands on at this point.All your other tests indicate a problem within the radio.All the external mute function look ok.

Thanks for that info. I was looking at that plug as it had 5 wires in it but was not sure. I disconnected it and it made no difference. The volume is still low. Let me explain about the volume level. It is not so low that you have to strain to hear it but if I had to guess I would say it's about as loud as if you turned the volume maybe 1/4 up on a normal working radio. However if I plug in my cell phone to listen to music it is quiet a bit lower. I am using the "i simple" device. In the beginning of all this I disconnected the i simple and took it out of the system but it made no difference.
A question for you...... With the mute button on left handle bar, how is it that there is 4.5 volts on the blue wire when pushed in and no voltage on either wire when it is out in the non mute position. Where is that wire getting it's voltage from ?

A quick look...It shows the possible source for the electric comes from the radio On the green/black wire..it feeds both the mute and tune up/down control

As I understand,the "I simple" device is a aux audio input and transmitts it to a FM radio station...So we're still working with a low volume problem.

Thanks for getting back to me but this does not make sense to me ?

If I mute by pushing in the mute button there is 4.5 volts at the blue wire and no volts at the green wire. "so where did that voltage come from if there is no voltage in the un-muted position"
If I un-mute it, botton is out, there is no volts at either wire. This is what makes no sense to me.
I don't want to get you off track but does this still make sense to you?
