1999 honda shadow 750cc wont start.key off ...tried hooking up led lights.. ran 2 grey wires from led lights together to headlight fuse turned key on ran 2 black wires from led lights to ground

Hi, Arleen before testing any electrical component in the Starting System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead acid batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand or clutch pull in switch/sensor.
9. Security alarm needs a reset.
10. Starter relay, solenoid, starter have failed or circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. The electric starter is working but starter clutch has failed.
14. Check for engine trouble codes.

More likely to be your ignition coils. They heat up and expand this can cause an open circuit which will close up again when it has cooled down. Although, a bad charging system may cause this problem. Check the battery voltage with engine switched off ( approx 12 volts) and with the engine running (approx 14 volts) If you are getting 14 volts then your battery is dead, if you aren't, then your charging system has a fault.

I am not totally familiar with this bike, but I do have several bikes of my own. If you have a fully charged battey, but no power at the starter motor this sound like a fuse has "blown". Try and switch your lights on or sound your horn, if these still work then it is likely to be an in-line fuse, if these don't work then it is likely that the main fuse has "blown", this is usually located near to the battery. You will need to check your wiring harness and you will find any in-line fuses. If there are no in-line fuses then there will be a fuse box somewhere on your bike.

If you do find a faulty fuse, you need to try and find out why. They only "blow" when they are overloaded. This is by design so that they protect major parts from being damaged. It may be as simple as you have a broken wire going to earth.

Took my bike out, WR450f 07 model, got to the shop...

If the battery is no good , this can cause some of the problems described, as the charge system tries to put out as much charge as it can, and not be able to charge the battery.
Try a volt meter on the battery, should be around 12v engine stopped and rise a couple of volts with the engine running.

Hi My motorcycle Hero Honda Dawn had problem at the time of starting a journey. The bike showing some Power missing alternatively . But it will solve after 10 minutes of ride, What is the problem Is it...

possible weak battery? its better after a run... when it's charged a bit off the alternator. it's possibly not holding the charge overnight and being a bit sluggish in the morning... have it checked - a half charged battery makes a half charged coil... zap? . which will spark but not quite so good as a fully charged coil ZAP!
also check the plug for oil fouling and check if the oil level is too high - if so drain the oil down to the Full mark - this can happen after a lot of failed starting attempts as unburned petrol gets past the cylinder into the sump, filling it up... If THIS has happened you need to change the oil and filter, oil full of petrol does not lubricate the engine!!! - I think its 10W30 for your bike, it takes about 2 pints.
Sounds like its almost definitely electrical tho...

Engine cutting out whilst riding along

If all the electrics go off then :-
A) Check tightness of battery terminals & condition of battery
B) Check for dodgy fuse or dirty connections
C) Check voltage across battery terminals when engine running - should be at least 12.5v rising with increasing revs to 15v max - if not then suspect the regulator/rectifier unit or the wiring from it to battery

I hope this helps, if so please mark as helpful.
Positive comments always appreciated

Dropping cylinder at 10rpm and possible generator /stater problem

It seems the charging system of your bike is not working
Recharge the battery and thn fit it in the bike and start it and check the charging rate.
Remember with lights 'on' it drains power from the battery butthe charging system of theengine takes over i.e. if its working alright, with your explanation, its for sure the charging system is not functioning.
Chekc the altenator and the rectifier.

Honda cb750 f2 1978fault on old bike ! electrical problem

From your explanation it sure sounds electricals, but surprising to hve a total failure to the electricals and thn it reappears after 30seconds!
Best would be to go through the wiring especially frm the battery onwards, the fuse box .
Since it is totally disappearing it should be a fault to those main wires could be lose connections somewhere!.
Hope this helps.

Battery drained while riding

Sounds like you either have corroded wires going to your battery or your alternator is not properly charging the battery. Get the bike to an autozone and ask them to put their tester on it.

please mark this as a fizya! thanks
