Somewhere there is a short circuit allowing the current to flow straight to earth on the engine or the frame. Blowing a 10 amp fuse means this is a very heavy current so do not be tempted to either fit a higher rated fuse or bypass the fuse. Almost certainly this would cause burnt out wiring and possibly start a fire.

This happened when you switched on the ignition and before you pressed the starter on one occasion. On other occasions the bike has started before blowing the fuse. This suggests that perhaps wiring with damaged insulation is making and breaking contact.

You said you have a new battery. Is it possible that during the fitting of this some damage was done to the wiring? Do you have a meter or can you borrow one? See if you can find out where this current is running to earth without replacing the fuse. ie check after the fuse with a meter.

At times like this it is good to have a friend that is an electrician to help you check.

Good luck.

SOURCE: Xchallenge won't start when engine is hot.

Check tightness of bolt where (carb/FI) goes into intake, and where intake goes into engine. Check gaskets in those locations, if any. Sounds like heat is causing some material to distort, causing a vacuum leak.

SOURCE: Brake failure light.

This is normal. Its part of the start up diagnostics where the sensors needs to see the wheels rotate 1 or 2 revolutions to verify proper functioning of the ABS system.

SOURCE: My 2006 BMW G650 has a brand new battery that died after 3 weeks

Sounds like you need to check your charging system.Battery when engine running alittle over idle should charge at 14.5 volts. If it does not check the output of your stator by testing lead at the regulator rectifier... It may be you have a bad regulator rectifier...

SOURCE: My wife and I have two bmw r1200c's a 2000 and a

No, very unlikely that the battery has anything to do with this problem

When you changed out the battery, did you remove the fuel tank completely or just prop it up??

There are two fuel lines (supply,return) and an electrical connector for the fuel pump that must be disconnected when you remove the tank.

I would suggest taking a close look on the RHS of the tank near the seat and ensure that the fuel pump connector is properly seated and that the fuel lines are properly connected.

Good Luck!

Electric starter not working battery ok

George, you have provided too little info to diagnose. But possibly: 1. Ignition key needs to be switched on 2. Bike is in gear 3. Kickstand is down 4. Bike is in a false neutral 5. Starter fuse (in fuse block) is blown 6. One of the leads to the starter is loose 7. Starter switch is disconnected or not working 8. Starter needs replacing 10. Lots of other possibilities beyond this, including (in newer machines) a possible fault in an electrical component the onboard computer has detected, so it prevents starting to avoid engine or component damage

My BSA A65 engine dies when I turn o0n the headlamp switch. Now the bike won't start and I have no lights working?

Sounds as if you have a short circuit in the headlamp circuit. While this could be anywhere, most likely a pinched wire somewhere you have removed and reinstalled some part. The seat? Replaced headlamp bulb? As to no longer starting, you may have blown a fuse due to the short.

I have a John Deere garden tractor 420 I was mowing the engine stopped I check the 25 amp fuse it was blown. I replaced it turned the key there is absolutely no power

Im gonna first assume that the 420 you have is the 1986 model and not the 68 model , second this model has hydraulic lift on mower , this model has a electric clutch on pto , I assume that you dissengauged the deck drive before trying to restart , but now if you forgot to do so before replacing fuse it would go again if it's what i think it is , so first disengauge deck second ck fuse again replace if nessacary , start engine attempt to engauge deck if engine dies or it does a short time later, ck your wiring to your pto clutch Look for what looks like a chewed up wire finding none replace pto clutch magnet (or entire clutch if lots of hours on it) also ck out my youtube video on finding electrical faults on lawn tractors this might help ya .

I have spark and it turns over I blown two power source 10 amp fuses and it wont start? and new spark plugs

It sounds as if your starter motor is failing, But as you don't say what make and model your bike is I can't be more specific. It could also be a shorting starter relay. the speed the fuse blows at would give more information. If it blows immediately, the you are looking at an electrical short, if it takes a little while then you are looking at an electrical overload, indicating a failing starter.

Few months ago had fuel pump assembly replaced. Not the pump but the assembly. Location is behind the rear seat above the fuel tank and actually its in the tank but can be reached by removing the rear seat...

I would say that you are on the right track , I think that maybe when the work was done on the fuel pump assy the mechanic may have pinched the power wire and hitting the bumps has caused it to short.you will have to take the seats out again (sorry).You need to look for a damaged wire or evidence of arcing .Hope this helps.

Primary fuel pump (15 Amp) fuse blown (in cold weather ?)

Primary fuel pump requires replacement. Your secondary fuel pump is used only for starting and WOT situations. This is why your vehicle will start, run, and die.
