Question about Harley Davidson FXSTS Springer Softail Motorcycles
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.
