Yes it can be faulty starter relay.Its actually starter relay.The relay gets power from battery and gives voltage to starter.If this relay gets faulty then starter will not start as it should.If the relay checks out ok then it can be loose battery terminals or dirty corroded battery terminals,that needs to be removed and cleaned.The relay is 12 volt part. If the relay is doing all those things but it still won't start, you'll need to look elsewhere like a bad starter/solenoid, loose or corroded battery cables. You my also want to check for 12v to the relay from the start switch. the location of starter relay is Under the battery box on the right side of the bike. It is the black module that is screwed to the box.

CHECKING THE STARTER "RELAY" The starter relay's function is to take the small current switch of your starter button, and close another switch that lets a large amount current go the the starter motor. It (usually) has 4 terminals on it. Two of them are low current (or low "tension"), and the other two are high current (high tension). Assuming the kill switch is on RUN, when you press the START button, do you hear the relay "CLICK?" If you don't, the problem may either be with the wiring leading to and from the relay, or it may be a bad relay.
Here's how you test the relay after you've determined you didn't hear any click(assuming your battery is charged): · Disconnect the high current lead that goes from the relay to the starter motor (it's usually bolted to the relay) · Hook up each of your multimeter probes to the two high current leads on the relay to test for continuity (Ohms) · Turn the key to the "ON" position and the kill switch to the "RUN" position and be sure the bike is in NEUTRAL. Press the starter button. If the relay "clicks" and the meter reads 0 (zero) Ohms, the relay should be ok. · If you heard no click or the meter doesn't read real close to 0 Ohms, let go of the start switch. Disconnect all wires from the relay (mark them so you know where they go back on).Measure the resistance between the two low current leads (where the small wires went) on the relay, if it's infinity, the relay is probably bad. If it's zero (literally) then the relay is probably bad.If its checked ok then the starter motor and starter solenoid are the faulty/weak part causing the issue.-----------------this will help.Thanks.Helpmech.

2009 Harley Davidson Softail Fat Boy won't start clicking sound


Hi, Foe before testing any electrical component in the Starting System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead acid batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Check the battery terminals for damage or corrosion check the 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.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand, clutch, neutral safety switch.
9. Security alarm needs a reset.
10. Starter relay, solenoid, starter motor or circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. Faulty ignition relay.
14. The electric starter is working but starter clutch has failed.
15. Check for engine trouble codes.

Hi Anonymous, on a Softail remove seat and directly behind the battery is a black plastic box. The cover slides up and off revealing the starter relay and the system/fuel pump relay for you injected folks and the various assorted circuit fuses. Good luck and have nice day.

Harley won't start ... starter not working custom softail ... 80 ci v twin engine... nothing happens when I push the starter button.... battery is fine and all lights work... clicking sound under seat...


That clicking sound you are hearing may be a circuit breaker tripping indicating a short circuit somewhere. I think the starter circuit is powered by the ignition circuit. If you have a short circuit in your ignition system the breaker will trip killing power to your ignition, thus the engine dying, and preventing power for the starter circuit preventing the bike from being restarted.

On your bike, I believe there is a chrome coil cover over the coil on the left side of the bike. Check and see if this cover has come loose. I've seen them come loose and fall down on the coil connector on top of the coil shorting it out. If that ain't it, just keep looking, there's a short somewhere. Good Luck

My 1998 Heritage Softail Classic will not start. It sounds like the starter is bad, just a clicking sound. Any suggestions?


First, take the battery out and take it to an automotive parts house and ask them to load test it for you. If the battery is good, put it back in the bike and reconnect the cables. Make sure they are clean and tight.

There are two things that could be making the clicking noise, the starter relay and starter solenoid. The relay makes a soft sound and the starter solenoid makes a loud clicking. Let's start with the starter relay. It is located on the front side of the rear fender. Look at the front side of the rear fender just below the oil tank. The relay is a cube looking thing about 1 inch on all dimensions with about five wires running to it. These fail quite often as water gets into them. When you press the starter button, you can hear a faint click. If you suspect this is the problem there is a way to test but you'll need a test light.

Look at the end of the starter on the right side of the bike under the oil tank. You'll see a pentagon shaped (five sided) plate. Up near the top of that plate you'll see a plug with one green wire running into it. Unplug this connector and stick your test light probe into the plug. Turn the switch on and press the starter button. If the test light lights up, the starter relay is good and your problem is in the starter solenoid. If the light does not light up, replace the starter relay.

You can get a rebuild kit for the starter. They are not difficult to install but you may have to pull the starter off the bike to repair it. Once you figure out what the problem is, repost and we'll go from there. Good Luck!

Possible starter going out on 95 Legacy


providing your battery cable connections are clean and tight, it is probably the solenoid (starter) thet is worn out... but check all your connections first.
