- If the starter is turning the motor , I dont understand why u replaced the relay and the ignition....but - thats water under the bridge now .... Open the primary and check the jack shaft... put a pliers on it - pull it out and turn it 1/4 turn a few times - make sure its not binding. Take a look at the bushing on the outer primary.... may need to bevel the edges a little. Make sure the battery is charged enough to give the engine a few strong turns. Let me know what you find

I have a 2005 fatboy and i replaced the battery. when i hit the start button the starter relay clicks and nothing happens. all my lights work and the fuel pump kicks on like normal. it just wont start


Sound like starter is stuck. Try giving it a tap with a rubber mallet, while pressing start button. If this does not work, put bike in gear and push it forward a few feet, then try again to start it. If still nothing try using jumper cables on battery, then start. If no go you have a bad starter.

Nothing at the start button


with ignition on try a turn signal for they are the ground connection, if they work switch your system relay and starter relay,this is a quick way to test if the relay is bad

Hello, I just changed the starter on a 91 fatboy. everything worked as it should for couple of days. Today when I switched on the ignition, the starter engaged without pushing the start switch. It did this...


The new starter has gone bad,or a drop in voltage(amps)has caused this.If you have a 2 amp slow charger,use it to charge the battery up 8 hours or so.Then try the ignition,and starter,and see if the problem has gone away.Also see if the ignition wire is interfering with the starter engage wire.And look at the engage wire to see if it is up against the large cable to the starter.If none of this helps,replace the starter.I hope this was helpful,if so,please let us know,thank you.

Voltage drops with ignition on


Sounds like the battery is bad. Try taking it to a auto parts store to have them load test it, but it sounds like you have a residual charge on the battery but it doesn't have a hard charge on it. if the battery load test comes back good, then you might have a problem with the ignition switch.

Dont sound right starting when hot


Batteries will charge up alittle over nite, so first thing in the morning you have the most juice. It could be a battery on the way out or a problem with your charging system not quite meeting all the needs of your bike.

first ya gotta figure out what clicks - is it the relay, or the starter ? In either event - you'll need a multi meter or voltmeter to trouble shoot it.... but since u just replaced the battery - start by checkin the battery connections especially at the starter. Torque em and rotate em to grind em in and make a good connection. If that s not it - you have a bad solenoid or starter motor or relay. oh - before you start replacing stuff - make sure ya gotta full charge from the battery

Harley start trouble


Just your average run of the mill bad starter. When you take the plugs out, you relieve all the compression from the cylinders, therefore there is no load on the starter, and it turns it over. Put the plugs back, and you get the compression back, putting a tremendous load on the starter. Replace the starter and you're good.

Hi,

Appreciate the vote of confidence but there are a few others who are likewise knowledgeable if not more..

On to your concern, it would seem you have two (2) issue, 1st if wont crank and the second will crank but not start.

No Crank: Due to the massive current required by the starter a component is installed between the starter button and the starter. This component then switches the battery to the starter motor. In cars this is the starting solenoid, in most bikes, this is the starter relay. Normally in the starter relay there would be 2 big terminals for the battery and the starter motor cables with 2 smaller wires for the starter switch and ground. Try this - try pushing the start button with the headlights on, if the headlight dims considerably, then the starting relay is good and the motor is bad; on the other hand if the headlight dims just slightly or not at all, it is the starting relay (the one with the clicking sound).

Most starter motor problems could be:
1. the bearings/bushings at the ends of the armature;
2. carbon brushes;
3. commutator segments (the multiple small copper plates that the brush contacts with).

However, it may be to your advantage to simply replace the motor should it be deemed defective, difficult to secure parts or not economically reasonable to go down component level repair.

Will Crank but not fire: There are 2 major requirement for a gasoline engine to fire, fuel and ignition. No fuel could be verified by removing the air cleaner and pouring a small amount of fuel down the throat, start the bike, if it start and runs (even for just a moment), you have verified the fuel problem. No ignition could be verified by removing one of the plugs, reinsert the high tension wire plug to the sparkplug and place the sparkplug atop any metal part, crank the engine, there should be a spark at the plugs.

Pls post back results whether fuel or ignition and we can go further from there.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Starter turns slow


poor connection or ground cables can look good and be bad just like me! also the sarter could be the problem if the relay isnt carrying enough amps when the starter engages
