2003 Ultra Classic shuts down

My bike loses all electrical power when riding in the city after it gets hot. Three dealers have performed numerous fixes to no avail. The engine is not overheating.

    No lights or anything, hav to reset the clock even after power comes back on. I have learned from others it is likely the circuit breaker tripping after it gets hot. This makes sense. HD needs to come up with a fix. After 2004 they started using fuses instead of a breaker. They had a recall on 2003's that had a 40 amp and replaced it with a 50 amp. They have replaced 4 of my circuit breakers. The wierd thing is my bike has over 66,000 miles on it and never had this problem except for the last year. I have had a couple of ignitin switches replaced also.

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.

Blowing fuse for cruise control 2000 HD Ultra green light go out while riding?


Hi, Agustin before diagnosing your blown fuse issue check the bottom of your seat if it's metal and comes in close proximity to the positive battery post you need to take the necessary steps to ensure there is no contact (electrical tape, thick rubber insulation, hammer a dent in the seat bottom etc.) also you are going to need a wiring from your service manual a test light, an ohmmeter and plenty of extra fuses. If you turn on your ignition switch and immediately blow a fuse you have a hard/dead short and is usually easy to find. With a test light connected to the hot side of the blown fuse holder start stabbing the wire/s that leads away from the fuse holder and towards the ignition switch, you test light will illuminate validating the short. When the test light fails to illuminate you have passed the short and need to back up until the test light illuminates, then look in the immediate area for the short.
If you driving down the road for 30 minutes or 15 miles and blow a fuse you have soft/flying short and may take some time and patience to find.
If the main fuse/circuit breaker constantly blows/trips while riding you probably have a faulty battery terminal connection. Check battery terminals for damage or corrosion, check 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 if necessary. Any other fuses that constantly keep blowing while riding are usually caused by a loose or corroded ground wire in the circuit, which means you have to check, inspect, test each and everyone with and ohm meter set on a low ohm scale 100 ohms or less . Simply touch one lead to the ground source and the other lead to the battery negative terminal, a reading of zero indicates a clean solid ground. Any number reading or infinity indicates a poor ground and needs to be repaired. Poor or weak grounds require excessive additional amperage to complete the circuit which in turn blows the small amperage fuse.

Good luck and have nice a day.

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.

I had a problem like that on my 2003 ultra classic. turns out there was a recall on some electric block in the fairing. It was a main connection power block kinda thing. Anyway they replaced it and then it never happened again.

it would ride a while on a hot day 25 min freeway and then just shut down. wait and cool down and it would restart.

I hope this helps.

i think you have a battery fault inside the battery there are lots of plates all joined up if there is a broken joint on the battery turminal post inside your bikes battery all the power just disappears just like that,,,but a slight bump may remake the joint and all is powerd back on again,,,if you could get hold of another battery just to try it out??? or take out your battery and hook up a lamp to it then give the battery posts a wiggel and the battery a thumping if the lamp gos out you just found the problem

2003 Ultra shuts off while riding


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????
