'92 GL 1500 keeps blowing fuse 9

Postby midnightjoe » Mon Mar 16, 2015 2:44 pm



It doesn't always do it but most of the time when I shut-off the bike, even for a short time, it blows fuse 9. I've checked all the relays and they read about 7 ohms. My bike doesn't have fuse 13, but fuse 12 is fine. I tried to put an ohms meter to the stereo plug ground and positive wire, but I can't make contact. It's a good bike; just need to rid it of a couple of gremlins.

Help is greatly appreciated.

I'll give you a generic electrician reply....since I have no 1500 schematic.

Check the Owner's Manual to ensure that you have the proper size (amperage) fuse installed. It's not good to have a 5A fuse when the circuit calls for a 10A. Pardon my ignorance (I'm more intimately familiar with GL1100s), but if the fuses are the glass cylinder type, CLEAN the fuseholder brass contacts! I have even bent those slightly to get a better contact (be careful if you do that).

Do a through visual inspection of the power wire for that circuit. You mentioned stereo, so I ASSume that is what we are dealing with.
The power wire may have some intermediate connections. It is a good practice to clean those connections. If it is a connector, even disconnecting and reconnecting that plug repeatedly can help scrub the corrosion from its contacts. I go a step further with spade terminals and pinch the female side a bit such that the spade is gripped more tightly. The same applies for the old bullet style plugs, and I have been known to roll sandpaper into a cylinder to scrub the female socket and you know to do to the male as well.

Lastly, there may a pinch or chafe somewhere on the power wire. A good visual inspection of the wires should surface that. Don't neglect to look at ALL the wires, including the speaker feed wires. If one of those were shorting to ground, it will draw excessive power from the amplifier portion of the radio and may blow the fuse.

I'll look on line and see if I can't locate a 1500 schematic. Since I have a 93 (new to me) it will be helpful to have.
When all else fails, RTFM!

Here's a trick.
When a fuse blows,assuming its the correct size,something is drawing too much current(obvious enough) but locating it is difficult.
Example...A blown 10 amp fuse..take a halogen lamp,like a old headlight,they need about 5 amp to operate.Attach the 2 wires from it "in place" of the fuse.
Turn on the key.The equipment will still work and the lamp should light up somewhat.As soon as you wiggle or create the short,the lamp will simply light up bright.No blown fuse and makes it easy to narrow down where the short may be.
Also be aware or wary of any add on wiring,even the plug for a trailer tucked away.

I just looked a my Clymer service manual for the 92 Aspencade wiring Diagram
the #9 fuse is a 5amp and it shows it going to a trunk light (optional).

On my 89 fuse #9 on is a 5 amp reverse system, #13 is a 5 amp for CB radio.

Just noticed there are 2 fuse charts. For basic model without reverse 3 9 is for : Stereo, Trunk light, CB radio (optional), LCD unit.

Fuse #9 is "backup" - that doesn't mean reverse, it means "radio memory and clock backup" - basically it is on at all times, even when the bike is off, to keep the radio station memorized, and keep the clock running.

This is also why it powers the (optional) trunk light, so that the trunk light works even when the bike is turned off.

My mistake, so used to only having an 89. I was looking at the cover of the 94 GL1500 that has 13 fuses. The 94 is going to be the project bike so I can keep the 89 intact.

My FSM shows fuse #9 is reverse start for the Aspencade and the SE and #13 is backup. Hmm.

"Back Up" is for CB radio, Stereo/cassette deck, Instrument panel indicator illumination, Trunk light.

Yes, I know. I was stating that because there seems to be conflicting info on what fuse #9 is. This IS a '92 Aspencade with reverse we're talking about?

I think I got it!
FIrst of all I'd like to say Thank You all for your help. I now understand that there was a change after '93 that listed the #9 fuse to the reverse system. Mine is a '92 and the fuse is listed as a "backup" for the radio memory and clock. They also added the #13 fuse then that did what the #9 fuse does on mine.

Getting to the issue(s) at hand... I believe the fuse blows because of the vanity mirror light wire plugs in the rear speaker housing. After the accident I was replacing the trunk lid I also added rear speakers. There are wires in their console that have to do with a switch that cuts power to the trunk light when the lid is closed. I didn't know how to wire them in so I left them unplugged. One of them has a rubber boot, but I think the other one might sometimes touch the speaker and short-out. That might explain why it doesn't always blow the fuse when I shut-off the bike. I have figured out how to wire the switch into the circuit so the problem should go away.... If that is the cause.

I've been riding with this glitch for a couple of years. I'm looking forward to getting the bike back together, and ride it.
