,il help you on this one,,,,so long as you dont try this again,,,ok!
first lift the fule tank to get to the relays under it in a black box,,,
take the lid of the relay box and look inside it,,,you will see a long black relay that is bolted down with a 10mm bolt and with two battery leads going to it near the seat end of the box,,,give this relay a jentel tapping with a screw driver,,,this relay is the starter relay and,,,,(its stuck in!) you have "welded the contacts together in it!" if it dont let go then its a new relay,,,and thats pricy!!!! £70???+!!!
thats what happens if you try to jump start a bmw!!!! with to fuw amps to turn it over!!! keep tapping the relay till it lets go and you can then hook up the bike's battery after you have "fully charged it first"!!!! so its got the amps to turn the motor over with out welding the starter relay up again,,,heres a tip,,,if your going to leave the bike standing around not in use get yourself a 2.5watt 12 volt solar battery charger and hook that to the bikes battery it wont over charge the battery but it will keep it toped up and fully charged,,and all it needs to work is good light,,,
see free power??? now go off and fix this bmw,,,easy realy?
and dont try starting her up on a car charger,,,use a car battery if you must,,but not just a charger,there is to fuw amps in it to start her up!!!

Motorcycle will not start


My first question is did the bike work OK before it was stripped and painted?
It is possible paint has got onto the main earthing (ground) point on the chassis/frame. I would first check that there is a good earth connection from battery to frame and all light units. Other than the turn signals coming on do any other lights show when you turn the ignition on? If no I would try checking the battery. Remove the battery from the bike AND THIS IS MOST IMPORTANT remove the negative lead first then the positive.
Check the battery has voltage approx 12.5 to 13.2 volts is OK, next connect a 21 watt bulb to the terminals and see if the light dims over 1 minute. If OK get a dedicated motorcycle battery charger (a charger for a car is no good) with an output of less than 1 amp. Charge the battery for a few hours. Refit battery into your bike AND THIS IS MOST IMPORTANT TOO re-connect the positive lead first then the negative.

WARNING never try to jump start your bike from a car/van etc. The more powerful batteries in these vehicles will fry your bikes electrics.

ALWAYS use a dedicated motorcycle battery charger.

ALWAYS remove and refit your battery as stated above.

Good luck and hope this helps.

I feel I need to get this message across to all bikers. YOU MUST NOT JUMP START YOUR BIKE IF YOU CONNECT IT TO A CAR,VAN OR TRUCK BATTERY YOU WILL KILL THE BATTERY. A motorcycle battery is far lower in power rate than the average small car.
Remove the old battery from the bike by disconnecting the negative lead first then the positive.
Get yourself a new battery fill with the acid supplied then charge it, DO NOT USE A CAR CHARGER IT WILL FRY THE BATTERY. USE A DEDICATED MOTORCYCLE BATTERY CHARGER WITH AN OUTPUT RATE OF 1 AMP MAX. A smart charger is the best bet or an Optimiser that you can connect to the bike battery and connect it to the the bike when not in use. This will maintain the battery power and voltage levels.
After charging refit the battery by connecting the positive lead first then the negative. Before trying to start the bike check the new battery voltage it should be between 12.5 volts and 13.2 approx. If the bike starts OK check the charge rate from the alternator connect a volt meter across the battery you should see an increase in volts up to approx 14.4 at 5,000 rpm. If so your alternator and rectifier/regulator are working. Hope this helps.

Bmw k75c fuelpump fault &or remove


Hi, Tonyhickey52 if your bike has been sitting idle for months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will idle and run poorly, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition.
1. If your battery was 3 years or older when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging remove the leads and let the battery sit for a couple of hours then check the battery voltage with a volt meter, you should have 12.5 volts or better, any readings in the 11 volt range you need to do a proper load test on the battery and replace as necessary, any readings in the 10 volt range you have a dead cell and replace the battery.
4. Drain and flush fuel tank, google " how to clean a motorcycle gas tank" find a couple forums to view the different options available.
5. Remove your air cleaner and clean and re-oil per Mfg. specifications.
6. Remove the carburetor, disassemble and decontaminate with a carb dip or if you have EFI remove injectors and clean with carb spray and compressed air
7. Remove fuel valve and filter disassemble and clean as necessary, remove fuel lines and replace with new ones.
8. Replace spark plug with a new one and check for spark.

My 2000 Suzuki intruder vs 1400 lost power all of a sudden. Nothing works. Could it be tge main fuse? Where is it located?


Hi, the main fuse is on the starter solenoid I believe. If this is OK I would look to the battery. I have had my SV get me to work and after work tries to start then nothing shot battery every time. Try removing the battery please undo negative lead first. Connect battery to a dedicated bike charger (output 1 amp max) see if it will charge. A dead or faulty battery will normally show full charge very quickly do not be fooled by this the battery is lying. When you fit a battery please connect positive lead first. Please never use car or boost chargers and never jump start your bike from another vehicle.

Hope this helps.

I own a 98 yzf. the battery was dead so i tried jumping it with a car i hooked the cables up with the car off. the lights on the bike went on so i tried to start it when i hit the ignition & the lights...


Yes it sounds like one. OK, find your abttery terminals, one is marked in black cable and the other has a red sleeve near the terminal. Follow the red cabel to a box that contain a 30A fuse, see if this is blwon, which most likely. Replace fuse and now use a trickle charger as car batteries has toooo much amperage to jump start a bike. If you have another bike battery it is fine to jump start, never try using a car battery as many damages can happen. Once battery is fully charged ( normally in 8 hours) try again for your bike to start. Cheers. If good give a return comment please.

Motorcycle battery seems dead, help locating/replacing/charging


Yes it is the battery. First try charging it with trickle charger. NOT car battery charger. It should work fine once it is charged enough to start the bike. Than the bikes should keep it charged. Or you can jump it with car battery. This is safe. THe motorcyle battery is also 12 volts. Just smaller.

After the bike runs for 5-10 minutes and shut if off. Wait 5-10 minutes after it is off and try again. If it does not start again, than your battery is either dead or your stator/rectifier (your charge system) could be faulty. Lot cheaper to get battery for $30 than to pay $75 hourly shop fees for testing and than repairing.
