Battery being drained

Postby dotman5614 » Tue Aug 09, 2011 1:43 am



Hello-
I'm brand new to this site and came across you after doing a lot of research. I posted this question/predicament on another forum, and have received several suggestions. I'm at the point right now that I am pulling my hair out, and figure anything I can receive information on will help me out. Please bear with me.

Here's my problem.....

88 GL1500

Had problem with what I thought was battery, so purchased new battery. Rode a while, then suddenly, everything began shutting down...including motor. Everything dead. Figured maybe battery was bad & replaced it. Same thing happened.

Decided it might be an alternator issue, so checked it with a load, on a fully charged battery. Rev it up & indicated only around 12.9 volts or so. Went to a couple of Honda dealers around here, and neither seemed interested in working on it. One even said, "I've got techs who weren't even born when that thing was made." OK, good & dandy...but I need some help!!!

Removed the alternator myself, took it to alternator shop, and they completely rebuilt it.....brushes, etc. Brought it home, mounted it back, made sure battery was up & charged, and it started perfectly. At idle, almost 13v. Rev it up, and it would show 14+ volts...nearly 15.

With that, I think life is good. Brakes were somewhat spongy, so bled front/rear, and take off.

Life was not good. Exactly 50 miles down the road, stereo cuts off, instrument panel starts blinking (clock, radio station id, etc), and it dies. Member of AAA, and tow truck brings me home. Check volts, and battery was at 10v. Put a charger on it, and after about 3 hours, battery was back up to about 13 volts. Cranked right up, and left it running just long enough to put it in the shed, and contemplating what harm I can scheme up to do to it!!!

Can anybody offer a suggestion as to what might be the problem? We are in a drought here in Texas, and my County is under a burn ban, so I cannot go out there & torch it!!!! I would hate to have to call my boss & tell him I'm in jail because I put my motor in the middle of my pasture, torched it, and violated the burn ban!!!!

Some suggestions from the other forum were:
1. A failed regulator (is that going to be built in the alternator?)
2. Main ground/ground wire to frame
3. Main dogbone (I had to look that up & understand now what it is) Where is it on the 88 GL1500?
4. Charging system harness (Where is this & how do I check it?)

It's nearly 2AM in Texas, and I'm gonna try to do something with it again tomorrow.

Hope I'm not totally embarrassing myself!!!!

Thank ya'll so much for any suggestions-

I think you got a drain on your battery from a shorted circuit start pulling fuses one at a time until battery quits drawing current

I don't own one,but here goes.My 1200 draws 10 amp just to get it to run.Yours most likely draws more.Without charging it,the battery won't last long(obviously).
I understand the alternator was rebuilt,however that doesn't mean it's working.
The alternator requires a "get it going"voltage from the bike.Start it and measure where I've circled.
If there is 12 volts there and it's still not charging,pull it again.
if the volts are missing,look at the relay.
Here's a generic schematic.Hope it helps.

Where are you checking your voltage at? See if you can check it at the back of the alternator. This can help determine if the alternator is the problem or between the alternator and the battery. If you haven't already, double check your connections to the alternator.
If all else fails then pull it and take it back to who rebuilt it and have them retest it.

Thanks for the imputs. Started from scratch again. Did a slow charge on the battery and have a fully charged battery. Before I cranked it, had 13.1v at the battery. Cranked it, let it warm up, and checked at the battery again. Only 12.8v, and thought that was odd. Throttled to about 2500 RPM, and only stayed in the 12.4-12.6v range. Never increased. Alternator ain't "alting". Removed it & taking it back tomorrow to have it checked again.

If it tests OK , look at the switched volts that energize it.I've circled it in a previous post.

Got the alternator back. Guy at the shop said the rotor got hot & had failed. He really felt bad about it because he said he should have caught it the first time. Put it back on, and @ 2500rpm showing about 13.5 volts. Kicked on highbeam, radio, stepped on brake, it decreased for an instant, but went back to charging. Hopefully this takes care of everything.
Thanks a bunch for the help & suggestions.

May I ask what he charged you for the work?

bhazlet-
When I took it in the first time & they did the brushes, etc, it was $86. On this last episode of taking it back concerning the rotor, etc, he didn't charge me anything. Just kept saying he was sorry. This is a reputable company. Have been in business since Moses was a baby. Rode it today for quite a while, and so far, life is good!!!!

You might want to consider mentioning their name. I like to go to companies that have a good customer relationship, we all make mistakes, what is important is how we deal with them. The company you used sounds like one I would like to use in the future if I have a need..

Gary-
It's gonna be A-1 Starter & Alternator at 431 Riverside Drive in San Marcos...512-392-5259. On the west side of the Interstate, just south of TX80. Owner is a man named James, and he's who I have been dealing with. Sorry, don't know his last name, but I'm telling ya....he's genuine. He's not too talkative, but "good people".
Stay Safe-
