20 Most Recent 2004 Harley Davidson FLSTF - FLSTFI Fat Boy Questions & Answers


Hi, Stanley before diagnosing your blown fuse issue, check the bottom of your seat, if its 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.) You are going to need a wiring diagram 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 an 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 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.

Hi, Brandon before replacing a new battery make sure your battery cables are clean, "CORROSION" free and "TIGHT" you may find your bike starts ok and you don't need a new battery. When removing an old battery always disconnect or remove the main 40 amp fuse or circuit breaker first then disconnect the negative cable, depending on accessories, reconnecting a new battery that is not fully charged or in the wrong sequence sometimes gives Mr. Electron a free pass to wreak havoc with your electrical system. Never put a brand new battery in a bike without charging it to 100% full capacity first. With the ignition and kill switch in the off position connect the positive battery cable first, then check your negative ground cable where it attaches to the frame or engine for a clean tight connection anything substandard will cause excessive amperage that can overwhelm delicate microprocessing circuits and fuses in the system when the negative ground cable is connected to the battery post, end result from your bike, it declines your invitation to come out and play. That being said the usual suspects are:
1. Security system needs a reset.
2. Improper sequence procedure for alarm override.
3. Key fob out of sync with the alarm system.
4. Key fob battery low or dead.
5. Key fob battery installed backward.
6. Fuel tuner needs to be reprogrammed.
7. Faulty run/off switch

Hi, Kevin ignition timing is nonadjustable your ECM takes care of that from data it receives from various engine sensors which fail a lot more than ECM's your best bet is to put together a condensed version of what's wrong with your bike and send it to the email address below and I will respond immediately.

To remove lift rear tire slightly off the ground then remove the shock attaching bolt and washer with a special Snap-On adapter PN SRES24 and then remove the flange locknut and washer with grommet at the front of the shock. To reinstall put the washer and grommet inside the frame and put the bushing over the stud end of the shock and put the stud end through the keyed frame tube and loosely install the flange locknut. THEN coat the shoulder of the shock bolt (1) with ANTI-SEIZE compound and the bolt threads with blue loctite and insert the bolt and washer through the shock end and pivot the shock to align the bolt and the hole in the rear fork. Then tighten the shock bolt with the Snap-on adapter and since the adapter is not going to be at 90 degrees to the torque wrench it will lengthen the torque wrench and therefore the torque value must be computed with a torque computer such as the Snap-On PN SS-306G.Tighten the bolt and washer at the rear to 115-130 ft-lbs (155.9-176.2 Nm) and tighten the flange locknutto 32-39 ft-lbs (43.4-52.9 Nm). Then adjust the shocks equally with a special shock adjustment spanner.



To adjust the shocks loosen the locknuts and turn the adjuster plates OUT towards the locknut to increase the spring preload for a heavier load or IN away from the locknut to decrease the spring preload for a lighter load. You should MARK the adjuster plates before you begin so you can know when you have equally adjusted both shocks to the same position.

Hi Debbie, even though a fuse at first glance may look ok it still could be faulty try replacing it with another fuse temporarily with another one from the fuse block if you get lights then you know the fuse is bad and needs to be replaced. If you still have no lights use a test light to check continuity on both sides of the of the fuse receiver their will be red wire with a black stripe going into the receiver and a blue wire leaving it, with your test light clipped to the negative side of the battery touch the inboard side of the receiver it should light up.
If not then check for continuity on your ignition switch where the red wire with black stripe connects, with the switch in the on position the test light should should light up. If not then you have a faulty ignition switch and the contacts underneath could be so contaminated with dirt and grease it's preventing a closed circuit and sometimes just a little cleaning will bring it back to life. If not replace the switch. If you run into difficulty with any part of this diagnostic procedure or just need clarification you can reach me at xlch@mail.com Good luck and have nice day

Hi Timautino, perform the following tests:
1. Fill acid type batteries to proper levels.
2. Charge battery overnight at 1-2 amps you need 12.5 volts or better after charging.
3. Hook up battery positive cable, then with your multimeter on the milliamp scale connect one lead to the negative battery post and the other lead to the ground cable. Meter should read 3 milliamps or less, 10 milliamps with a radio, 15 milliamps with radio and CB. If your meter reads higher you need to isolate the circuit by pulling fuses and circuit breakers one at a time and observe meter for drop in aprerage then get out your test light and track down the short in that circuit.
3. Make sure all connections are clean and tight especially the negative cable at both ends.
4. Hook up volt meter to battery and start engine, if meter falls below 9.5 v while cranking replace battery.
5. With engine running at 3600 RPM battery should read 14.3-14.7 volts if not continue tests.
6. Unplug voltage regulator from alternator at crankcase by front of primary cover.
7. To test voltage regulator go to: https://www.youtube.com/watch?v=F8EjV0IjW9Q
8. With ohm meter, one lead grounded, touch alternator pin meter should read infinity, if not replace stator.
9. With ohm meter, both leads touching alternator pins meter should read 0.1 to 0.2 ohms on 1989 and later models. 0.2 to 0.4 ohms 1988 and earlier models, if not replace stator.
10. With volt meter set on AC scale, both leads touching alternator pins meter should read
16 to 20 volts AC for every 1000 RPM'S 1989 and later and 19 to 26 volts AC for every 1000 RPMS. If not replace rotor.
