Electrical short gl 1500

Postby smitty99 » Sat Apr 04, 2015 12:01 pm



Hey Winger's
First time post..........
So i bought a 1988 gl 1500, checked it out, had to jump it at the sellers hse (red flag) but decent shape for the years. So heres the problem, i put a brand new battery in it fully charged from the honda dealer, went to ride it a few days later dead. Got my meter out and checked for parasitic drag on the battery and you guessed it .8 of a amp draw all the time. :( So far i cked the big wire off the alt to see if it had bad diodes shorting to grd......no change, next went to fuse box pulled ea fuse down the line..... got to fuse 10 labeled "acc" pulled it........meter went to 0 BINGO found the circuit that has the short. I'm using a 89 European man for my 88, should i buy the elec troubleshooting manual for 88 model and start looking at all things hooked to the acc fuse circut ? Thanks for any help. Smitty.

The first thing I'd start looking for is any add-on's, wiring that is coming off the accy terminal at the fuse block.

Sounds like you have a dead short to ground.

So there is a live wire somewhere on your accessory circuit that is earthing out. Remove the fuse for the time being, then ensure that all other things are working successfully. Then start hooking up your accessories one by one - the one that trips the fuse is the circuit you need to look at..

good luck

800 MA isn't a dead short.A dead short would blow the fuse.There's an unauthorized draw of power.That ACC circuit should be dead when the key is in the off position.
I also use the euro manual and I'll check my draw asap.One thing I did notice from the schematic...Fuse 10 (acc) fuse should have no volts on it with the key in the off position...If there's volts there with the key off then either the ignition switch is bad or something added to the bike is back feeding the acc line.The acc line feeds the radio and it certainly could draw the 0.8 amp in idle mode.
Probe the acc terminal on the fuse block.Does it go dead with the key in the off position?
Is there anything not original to the bike...Something that hooks to ground,power and ignition wiring...a trailer plug,alarm system,alarmed on volt meter...etc.
It's even possible the radio has a bad circuit and is back feeding the acc. line...Unplug it and test again.

Thanks guys...........
I was able to down load a circuit schematic in block form which will help. Now i'll check the fuse 10 "acc" circuits that virgilmobile posted, amazing how well you responded, your experience and how many post you have. Can't wait to get back on it after Easter and troubleshoot your tips.
I was able to rebuild my brake calipers, changed my timing belts/
tension pulleys, compression ck, new spark plugs and more using goldwing doc's. Now i'm glad i registered here. I'll update and let you guys know what i find on this electrical problem. Happy Easter to all
Smitty.

Thanks again guys for the help, problem solved, i traced the electric draw to the key pulling out when it was still in the acc."on" position, worn key i guess. My wing is up high off the garage floor on my lift, and it was hard to see it, I've not rode the bike yet so it was a stupid mistake on my part. Special thanks to virgilmobile when you posted there should be no voltage in the acc circuit unless the key was on the acc. position, that led me to check it....... and it was in fact still on even when the key wasn't even in the ign. switch.....Smitty

Good find.Probably a good idea to add a small digital volt meter to the ACC line.I have one on mine.You can just see it through the left side near the forks.Its attached to the inner faring.
Did you happen to measure the drain on the battery with the key off?

Sure did Virgilmobile, the current went to zero, i thought there might be the max allowable 5 miliamps the manual says, maybe for the clock ? Not sure.....been checking the batt. everyday and it holding great!
I cant wait to get the plastic and seat back on and ride for the 1st time. i'm going from a sym 250cc scooter to this car on 2 wheels LOL :>) She's about 860 lbs. if i read the spec's right. I have rented a Harley road kings 8 diff times so i have some experience on bigger bikes. I ride with a local chapter of the CMA and it's been a chore to keep up with their big cruisers as i'm a big fellow .

You the man virgil, you saved me $90 buck an hour at my local honda dealer. I'm amazed at your 6600 post, look forward to maybe getting some more of your good advice in the future.............GB.............Smitty.

Great to hear.I expect a little drain from the radio(channel memory and clock) but as the book says...
Keep us posted and post a few pictures too.
Side note:My wife still calls me "Smitty" too.An old nick name from 40+ years ago.Except my sisters and Mom,everybody in my family was called that.
I did find counterbalancing that weight in slow turns helpful.Just remember..if the bike is moving,feet on the pegs.Bad things happen if you try to bully that bike like a dirt bike.

Ok Virgil on the nick name....... good news i was able to get it off the lift table and ride it for the first time tonite , WOW! compared to my little scooter this thing rides like a caddy, wide windscreen, good wind protection on my legs, at first when it was cold it had a hesitation in it( used stabil in it this winter) but by the time i rode it thru the park (about 5 miles round trip) the throttle seems to be working normal. I do have to watch the weight though, i had some gravel on the street at the end of my driveway and i could feel my feet slipping a little. Our "CMA" chapter is having a bike blessing and 100 mile ride the 1st sat. in may so i need to get up to speed and practice riding it as we normally have 250 - 300 bikes show up for the ride. I did notice that the temp Gage isnt working so i got to get on that for sure. The needle moves and is lite up when the key is turns on, but it moved very little during the ride. Temp was mid 40's on the ride. Would like to check the diy's for checking the cooling fans...........be nice to know if they are working before we see hot weather. Nice meeting you on this forum..........O'll Smitty.

You can do a manual check of the fans, see if they turn easy without power. Check fuse # 4, fan power.

Mine needs a new thermostat too.When its cool,it takes forever to get to midway temp.To test my fans,I set the rpm to 1000(better charging) and let it run in the driveway.Takes 15-20 min.to get it up to temp where the fans kick on.just a bit below the hot mark.Not even close to the red.

Thanks guys........ good advice, the needle did move from far left up to the cold mark like Virgil's, so i'll keep the Honda brand coolant topped off and keep an eye on it. Looks like a lot of rain the next few days, can't wait to get it cruising again. After working on it for 4 mo.s i'm studing the owners manual now to see how things work :>) Take care.........Smitty.
