2003 883 sportster loses all electrical power while riding

Everything went dead during a ride, no lights, no horn, no dash, won't crank or push start, battery has power, checked and/or cleaned master fuse and secondary fuses. Using a wire tester there is no power getting to fuses?

Make sure your battery cables are tight at both ends. The ground connection on these bikes has a habit of vibrating loose.

SOURCE: FIRE and FUEL........NOT CRANKING !!!!!!!

check your ignition fuses but i think your problem is between your module and ignition switch if you got safty switches on there any one of them can cause that also.

SOURCE: harley davidson battery went dead after riding

1.What?

2.What?
You charged the battery off of the battery charger with a trickle charge. The battery wouldn't charge while you're riding, because your alternator took a cr@p.
(Sorry if I seem gruff, but I'm an old biker, and Harleys are all I ride. I'm also a Harley mechanic.
Shhhh! I don't want that to get around! lol!)

3.Battery is at 13.4 volts now? What is the specific gravity of the acid in each cell? Don't have a hydrometer? Do you have a load tester? No? Since you measured the voltage, do you have a multimeter?

Test the voltage with the bike running. It should be around 14.6 volts when charging, less with the battery fully charged.
Don't get the correct reading, then you better look at alternator replacement. (Regulator is built in)

Sounds like the voltage regulator is not working properly.

Start with the battery, make sure the wires are clean and secure, especially the ground. Make sure the battery is fully charged. Make sure the main fuse is still good. Let us know what you find.

My MTD Yard machines riding mower won't start.

Probably dead gas from sitting too long. Dump it out & put in fresh gas.Could have moisture in it. Pull out spark plug & crank it over several times after putting gas & let it sit a while to dry out or blow it out with compressed air. It should go.

I have a 883 harley davidson sporster, was riding the bike and road over a bump and bike shut down and won't start

I'd check the battery first. I've seen the post break loose from the batteries in many Sportsters and leave them dead on the road. I've only seen this happen once on a Big Twin. Why? I have no idea. If nothing on the bike works, this may be the problem. If everything else works but it just won't start, I need more information. Does the starter engage and the engine turn over?

One of the lights wasn't working. I jiggled the wire, it went on for a second then a pop noise and everything went dead. Won't turn over or anything.

You have stumbled upon a direct short that has to be repaired first. When you find the short you will need to find why the insulation is worn. Correct why insulation bad, then use electrical tape to wrap the spot and a couple of inches on either side of it. Find the fuse and replace it. You should be good to go.

I have a 2001 XL1200 Sporster and it just died one day while riding. If it cooled off, it would run for a little while and die again.

Have you checked to see if you have fuel IN THE CARBURETOR? In 1996, Harley went to a vacuum operated petcock and they've had troubles with them. The diaphragm in the backside of the petcock gets a hole in it and it doesn't allow for a full flow of fuel. Ride the bike with the air filter off until it quits. When it quits, look into the mouth of the carb with the engine not running and crank the throttle grip to wide open throttle. There is a brass nozzle standing just inside the mouth of the carb. When you crank the throttle grip to wide open, you should see a stream of gasoline squirt into the carb. If not, the carb has no fuel in it even though the fuel tank may be full. You'll have to drain the tank and remove the petcock. Take the plate off the backside and take a look at the diaphragm. Gently stretch it while holding it up to the light and check for holes. Personally, I'd replace the petcock with a high quality mechanical petcock and plug the vacuum hose. You'll have to manually turn the fuel on and off old-school style but you won't have anymore petcock problems.

Good Luck

Electrical trouble

If all the fuses turn out good especially the main fuse then you might want to check your starter solenoid. Try jumping the two leads on the solenoid if the bike starts then most likely the solenoid is bad. If it doesn't start then it could be two other things. 1- your Ignitions might be shoot. tell tail signs. Bike cutting out during the ride and bike loses power when you hit the starter button but power returns when you turn the key off then back on. 2- The Rectifier might be gone. The rectifier will cause many different problem that might have you chasing carb problems, to the bike won't start at all with no cranking
