2003 Ultra shuts off while riding

While riding my 2003 Ultra it shuts off very intermittantly . Loses battery voltage like the key was shut off or battery disconnect ! Wait 20 seconds and the circuit breaker closes again and it may be fine for 100 miles or it may do it again.

The voltage doesn't stay off long enough to clear radio memory but the speedo will stay at the speed the bike was traveling even tho it is stopped. Watching the volt meter it does not fluctuate. It does not appear to be heat related and has happened in cool , hot, rain, Etc !. Seems to happen more 2 up ?

I tightened everything I could find but have a feeling there is a crushed wire causing high resistance and opening the circuit breaker. But where ? The bike did have a recall on the breaker which was done and I replaced it again ( just because)

If anybody has had this complaint or knows the ancwer Thank You... I will keep digging and if I find it I will let you know !

How many lights are you running? try disconnecting the battery and hooking up a shunt with a volt meter or a current meter inline. then check the current with different accessories or everything running. If you have a big load and stereo amp you may need to upgrade the charging system and the Circuit Breaker or try a aftermarket CB.
It happened once to me, riding slow, new pavement, very hot day, spot lights and stereo amp on.
Have a new CB on order but, put on another 4000 miles without another problem????

2003 ford explorer shut-off while driving and it won't turn over, no sound when key is turn.

If the headlights work, I would check for voltage at the key switch and the major fuses.
If nothing works, I would start at the battery and work toward the fuse boxes. Could be a bad ground connection too.

As i'm riding the engine will shut off sometimes and I have to restart at the start button. Any Ideas?

I also have a 2003 Ultra that would shut down for no reason while I was driving, started happening 3 months after I had the bike, very dangeous, happened in a curve once, took it to the dealer and they were having problems a module for the ignition I thought. They replaced it twice, then told me that because I had a trailer wiring harness hooked up that was causing interferance, they took that off and havent had the problem since. Didnt use the trailer hitch much anyways, but dont know at this point if it was the module or the harness. Hope this helps.

No start...2000 Wrangler 4.0liter, automatic.

To me it sounds like you have weak battery. Hook up a meter and check voltage. should be over 12v, then turn key on. should maintain 12v. then crank. If the voltage goes below 11v cranking the battery is bad. Be sure to test the battery. Not the cables. Then tst the cables. You may have good voltage just touching the battery and you may have low voltage touching the terminals which would indicate a dirty connections.

2003 Ultra Classic shuts down

Could be the regulator/rectifier unit at the front of the engine. I replaced one recently with a new ,non genuine Harley part and that was faulty too. When I replaced that the problem was fixed. Don't waste your money on cheap parts.

This has to be a blown fuse. If it happened slowley you lost your altenator or battery connection.

Zooming causes shutdown

I think your battery is weak, not holding current or not enough.

Before buying a new camera's battery, try to discharge the battery because most batteries have memory problems.

Find a small light that is rated up to the battery voltage.
Connects two wires to battery and then to light.
When the light goes out, battery is fully discharged.
Now, charge up the battery with the camera's charger
Try it on the camera.
