Electrical Problem !!
Hi all, just getting the 3aj ready to go back on the road after winter. been starting her now and again this last few weeks, last week the battery was flat(brand new last summer & been kept on an optimate charger!) anyway i put a car charger on the battery(still in bike) & left it to charge for a day or so. now when i hit the starter all i hear is a buzzing sound coming from the solonoid, i got another solonoid from a breakers and fitted it today but it just makes the same buzzing noise!!! anyone have any idea what has went wrong? could something have burnt out because of the car charger being connected and if so, what? thanks for any answers in advance. Big T

Best bet.... if your battery aint dead from charging from a car charger
The buzzing sound from your relay is caused by your starter motor brushwires being cooked by having it on the car charger and short circuiting and or petrol leaking from the carb overflow onto the starter...mini whoosh. This short circuit drains the battery at a greater capacity then it can deliver hence causing the relay to bounce. Remove the starter motor and reinsulate or replace the brush wires.
...because it happenned to me too lol.

even so it's not a good idea. You can boil the battery at surprisingly low amperage.

The buzz is due of the flat battery or low power of the battery.. I had (and still have) the same problem but I've fitted a kickstart and fitted a new battery I had at home but yet have to get a new regulator/rectifier because it won't charge the new battery.
Clean the solonoid contacts and the contact on the cable at the starter motor, and also, the battery contacts... if they have any type of corrosion of course

Hi, the battery is now fully charged and i,ve checked all the connections also. still buzzing. I,ll have a look at the starter motor tmw. thanks again. any other sugestions welcome.

don't forget to check the regulator/rectifier that is under the rear fender...change it with one of a friends to see if it is it that isn't charging the battery.... I have to get a new one for myself to

Use jump leads to a good battery as a test

My bike has been doing the same sort of thing - I agree that it is very likely a knackered battery, for whatever reason, including, probably, using a car charger for a low-ampere bike battery.
In any case, mine has most of the symptoms that you describe, but it works just fine when jumped to a car battery that is in good condition - that's what tells me that the bike battery is u/s.
Even when "fully charged", it shows about just 12.5 volts on a multimeter.

Yes, it might be "fully charged" but it doesn't have enough power to turn the bike on..
On my 1990 XT600E what happened was that after I charged the battery and went for a short ride and turned the bike off, it wouldn't start again. it would only buzz when pressing the e-start .... even with my new battery, it keeps going flat and doing that.

Yr battery has gone
Definitely. To verify, hookup a car with jumper cables. Bike will start.
So, now to find out what f*cked up the battery: before damaging a new one, hookup the same car battery to your bike's electrical system via the jumper cables, disconnect the car's e-system from the car battery. Start bike. The charging voltage should go 14 - 14.5 V. If not, something wrong with the charging system.
On a side line, make sure that all the earth connections are clean & continuous, the thick black cable from battery to one of the starter motor fixing bolts, and the one small cable providing earth to the 'low amperage' part of the e-system.
Somewhere on this site there is a good fault-finding guide for charging systems.

Just about 12.5 volts
I typed that last bit in something of a hurry: to explain/describe it a tad - the voltmeter showed around 12.5V with no load on the battery just after the charger was disconnected (somewhere around 12.3-12.5V).
As soon as the starter motor was turned over once for a few seconds, this voltage reading dropped to about 11 volts, and it had the same symptoms described by big t -- basically a buzzing solenoid; no way was the bike going to start with that fully charged battery (charged with an "accumate" trickle charger that acts like an optimate). As soon as a car battery was jumped to the bike battery the bike engine turned over and started fine.

Hi when you disconect the battery from the charger you should let it stand for half an hour before checking the voltage,
You can get the battery tested with a meter which will test it under load a good bike shop should have a meter I think it may be called a drop tester.
I think you should have at least 12.5v after charging usually higher.
I have had a few batterys that will show 12.5v but will only turn the engine over once or twice and not fast enough to start. Even if battery is showing 12.5v it is the amps that give the power to turn the engine.
some good info and links about batterys here Dan's Motorcycle "Batteries"

Thanks Bolla, especially for the reminder about Dan's website: that's a really good resource with lots of useful information.
I don't know anything about the age of my battery BTW: it was on the bike when I bought it.
big t,
Suggest you have a read of that link from Bolla - tells you the bad news about using car battery chargers (we've all been there at some time or other!).
It's often been said in other threads, bad batteries can cause all sorts of nause and perculiar symptoms: I still think that is your main, or only hopefully, problem.

It's the battery - I had the same problem with both my Transalp and my tenere. With the engine running, if you put a meter across the terminals of the battery, you'll get about 14.5 volt reading. Turn the engine off and keep the meter on there. It'll read about 12.5. Keep the meter on and watch the volts drop slowly i.e. 12.4 - 12.3- 12.2 etc. This means that the engine is sending enough power back to charge the battery, but it's not holding the charge. Just get a new battery, and see what happens, they're fairly cheap. Or look at it like taking an aspirin - It may fix the problem, and it won't do any damage.
