GL1500 BATTERY REMOVAL

Postby boregard9 » Mon Nov 10, 2014 4:14 pm



I just got my 92 GL1500 home last night. I rode it about 200 miles. It sat about two hours and the battery was dead. I put a charger on it and charged it overnight. I took it out today for a short 30 minute ride and shut it off in my driveway. Within a few minutes the battery was dead again. I know where the battery is, but I do not know how to pull it out. I have searched the forum and could not find any information. I am mechanically inclined, but I do not want to pull anything apart if I do not have to. I would greatly appreciate information on how to remove the battery. I want to have it tested before I start electrical troubleshooting. Thanks

First thing you do is remove the negative connector - that's the one on the left side (nearest the back end of the bike). Unscrew the screw and remove the terminal ring, make sure it is not touching the battery terminal. Then do the same to the positive connector.

Next, remove the screw holding the bottom of the hold-down bar in place - in this picture you can see a terminal ring with a red plastic sleeve connected to this screw. Yours will not have this wire - just unscrew and remove the screw:

Flip the hold down bar upward, and the battery can then be pulled straight out.

That said, I suspect you're going to find the problem is not your battery (which may well be damaged and dead now), but your alternator.

Thanks for the clear instructions. I do not know what the problem is but I feel that checking the battery is the easiest first step. I rode it today for about 30 minutes and when I shut it off, it would not start, the battery was dead. I charged it for about two hours and it started and ran for another 30 minutes. It was fine when I parked it in the garage tonight. I will let you know what I find out about the battery.

Now is a good time to add a volt meter to the bike too.

I got a "new" to me '95 Wing last year. It does have a voltmeter on it. Dumb question, I know, BUT what do I actually look for on the meter? How do I tell if the battery is getting low, or charging correctly, or what?? Are there certain numbers to look for?? Thanks for your info.

If it is showing below 12 volt when running, your battery is not being charged. It should be showing a little over 14 volt when running.

It really kind of depends on what alternator you have in the bike.

A stock alternator will show above 12.5 volts at idle and 13.0 volts or higher above 1200 RPM.

The numbers vary depending on lights illuminated and or fans running. At any rate, the battery voltage at rest, ignition off, should never go below 12.7 volts. While riding, the voltage should never be above about 14.7 volts and will usually be about 13.5 volts.

Every system is a little different.

That's correct about the different voltages showing.
For me,the easy was to look at the volts showing when I turn on the key.Thats when the battery is not being charged.Actually it's discharging about 10 amp.
While driving,I kinda look once in a while...expecting it to be above that.
I don't worry about a few tenths of a volt changes.
I would be aware if it went too high tho.above 14.5.
On the 1100, it would vary from 12.8 up to 14.4. Depending on load and rpm.
My 1500 runs from 13.1 to 14.1 on the original 1988 alternator.
I'm mainly interested if it falls below 12.6 or above 14.6.

You may want to check the alternator output before pulling the battery. As stated, it may be in the 12.5 range when at idle, but should be approaching 14v when at 1500-2000 rpms. Also, check to see where your voltmeter is getting its reading from. It needs to come right off the battery or as close as possible. Connected to a lighting circuit, it will never read battery voltage accurately. There is always a voltage drop in the wiring that leads to the lights. Best is to use a known good volt meter and take the readings right at the battery terminals. You could also compare those readings to the bike voltmeter to determine accuracy of the bike meter.

When you do pull the battery, take it down to your local Auto Supply store and have them Load Check it. That will tell you if the battery is good or bad.

I agree, based on the symptoms he has described, it's far more likely that the problem is the alternator than the battery.
