Radio memory not working, fuse?

Postby gordonv » Sat Jan 23, 2010 6:58 pm



Thanks in advance.

I recently bought a 82' GL1100 Aspencade, and I am trying to fix the little problems I inheirated.

My radio memory will not store the stations when the ignition is turned off. I can save them while the ignition is on, move between them, but shortly after turning the ignition off, then back on, the memory is wiped out. I take it that the radio is not getting power while the ignition is off, and therefore the lose of power results in the memory wipe. I've checked the 7 fuses that I found within the faring, all are working. The main fuses are also fine.

Before I spend hours trying to trace it, which fuse/wire am I looking for? The manual shows a red wire 5A fuse going to the radio. Is it the power AMP or the radio that is losing the power for the memory?

I believe the radio memory fuse is a 1 or 2 amp one. In any case, they're not marked, so it's a case of trial and error.

Remove the left front turn indicator, and in behind it you'll find a rat's nest of wiring. In amongst that rat's nest are several white in-line fuse holders. Those are for the radio, intercom and power amplifier. One of those is the radio memory fuse.

Thanks WingAdmin,

Seems there are so many forums, each done a little differently. I did a search in Tech, and only came up with the post about the battery discharge and the radio. I posted the question here in Tech, seems I missed scrolling down and seeing there is an area for each type of model (GL1000, 1100, 1200, etc.) so I both searched and posted in the wrong place.

I did just find the post about the .2A fuse for the radio memory. I had found earlier about the other fuses being behind the left turn signal, and I had checked the fuses there, which are all working fine.

Seems I'll just need to go in there again with the meter and figure out which wire(s) have power when the ignition is off. Since my fuse was not burnt, I suspect a broken power lead to the radio.

I spent a few hours looking over the pictures at bike bandit, to do with the radio, main wire harness and the fairing harness. I was trying to find the fuses that show up in the schematic of the radio wiring in the service manual, which shows the power lead from the battery, that is hot at all times (must be for the memory), the red wire, passes through two fuses, a 1A and a .5A.

I had checked the fuses behind the left turn signal, but now armed with the knowledge of "The Red Wire" and knowing the right fuses from the list of components from the pictures at bandit, I was looking for two types of fuses holders. The flip open was to be the 1A, and the cyclinder/bayenet style holder was the .5A . Either could be blown.

I tried again, and this time removed the fuses, and it turned out that the 1A was blown, and lucky for me there is a spare in the lid of the flip holder (that's why they are so large). Memory is now working.

I hope this helps anyone else who may have a power/memory issue. There are two fuses on the 82' Aspencade.

Thanks WingAdmin

When I first got my 1100, I had the same problem - the radio wouldn't hold memory. I went hunting for the fuse, and like you, couldn't find it. I found the wires that had power even with the key turned off - and they were fine. I spent hours trying to figure out what was wrong.

It turned out the fuse was just old - and the ends where the glass was fastened to the metal end was loose. When it was sitting there, everything was fine. But as soon as I took a ride, the jostling would work it loose, and it would fail. I'd take it all apart again, check it, and it was fine again.

It wasn't until I decided in desperation to actually CHANGE the fuses that I fixed the problem, and figured out what was going on.

30 year old fuses don't hold up like they used to! :)

I see why you always suggest changing the main 30A fuse with a regular blade type wired in instead.

Yup - that master fuse is made of thin metal, and is right next to the solenoid. They tend to crack as they get old, and when they do crack, they can cause flaky operation like this. Most people replace them with a waterproof fuse holder like this one:



That way you can just plug a regular car "blade" 30 amp fuse into it and not worry about it ever again. I was stranded once because my old "dogbone" fuse failed. That was the last time THAT ever happened. :)

Thanks for all the interaction on this topic--I'm learning PLENTY. (I will use your advice to fix my radio memory--and will be picking up a new 30A plug-type fuse device too.)

Well, after much detective work, I was able to fix my radio preset problem this morning. Turns out my bike had a 7.5A blade-type fuse mounted beneath the left side accessory pouch. It was definitely blown. Right nearby was a little plastic snap pouch covered in 30 years of road grime. It contained three spare 7.5A fuses. I popped one in and everything works.

I learn more and more about this bike all the time, thanks to you guys.
