The pre-2000 models came with circuit breakers instead of fuses. They look like little metal cans that are about 1/2" wide by about 1 1/2" long. When a short circuit causes the current draw to exceed the rating of the circuit breaker, it will break with a slightly audible "ping". After a few minutes, it will reset itself. If the short circuit is still present, it will simply start the cycle all over again.

Now, there is a main circuit breaker. Usually it's under the seat and it's rated at 30 amps. It could have been replaced with a fuse by a previous owner if the bike was purchased used.

Now, at the battery or the starter, you should have an additional wire that supplies power to the entire bike. The large battery cable connects to the postive side of the battery and then goes down to the starter. Your bike should have the Nippondenso type starter on it as the '88 year model was the last to have the seperate starter solenoid and Hitachi starter. At one or the other places, the starter or the battery, there should be a large single wire connected along with the battery cable. This wire is the what I call the "accessories" power wire. It must be connected or there will be no power to the rest of the bike. If you failed to reconnect it at the battery, this could be your problem.

If you will contact me directly and tell me you need a schematic for your '89 FLHS, I can send it to you e-mail. [email protected]

I have a 2003 DynaGlyde, Carbureted, security and a battery that holds charge. The bike sat for a year I went to pick it up got it home in the back of my truck threw my battery charger on it to 15 amps...

Man, that's the best description I've ever seen of a problem with a bike on this site. Regrettably, I don't have a clue as to what the problem is but I can tell you that I've read about the turn signal staying on in many instances. I'm an old school biker and mechanic and I don't have any experience with the computer controlled bikes or security systems. To me, it sounds like the security system has got the bike disabled for some reason. This seems to be the case mostly when the battery goes dead and then the owner recharges the battery or installs a new battery. The security disables the ignition system thinking someone is trying to steal the bike and it communicates with the owner or mechanic through the turn signal system. Have you read the owner's manual about the security system? The turn signal staying on constantly may be trying to tell you what the problem is. I really wish I could help more but that's all I've got.

Good Luck

My back left blinker went out I replaced te bulb but still inop is it a fuse and if so what 1

a lot of vibration on that bike. follow the wire and make sure there is now loose connections. The old bulb was it actually blown out? could you see the wire was blown. try switching the bulb with the other side to verify the bulb is bad. If both the old and new bulb is for sure blown then it could be youre regulator going out. That restricts how much the battery is charged, if it is charged too much it could pop a bulb, however usually it pops the tail light first, just depends on how the manufacture has things wired.

A 93 flhs loosing charge in less than 2 hour

sounds like your battery is not charging from the engine. Most likely the cause of this is, a faulty Rectifier.
I suggest you charge your battery up, put it in the bike and start it up. Using a Volt meter, check the reading, to see if charge is going into the battery, reading should be about 14V with a little rev of the engine. If the reading remains at 12V, then ther is no charge going in.
If you have charge going in to your battery at idle, 13.5 - 14Volts,
Then i suggest your battery is faulty.

Voltage problem when running bike

The voltage regulator should present 13.5 to 14.5 volts at the battery to charge it properly (engine at fast idle). I'm not sure if the V regulator is adjustable or not. If not, then it probably needs to be replaced. The alternator appears to be trying to do it's job, although it may have an open diode or winding if the alternator is 3-phase. An oscilloscope is the best tool to check for all three phases working properly. Good luck!
