HD FXR 3 Wont Start
Twolanerider:
That's an electrical relay. Hearing it click there isn't (necessarily) wrong.
Does the starter itself click? If it does your problem is downstream from the starter relay. If the starter does nothing at all you need to check more.
Get a simple test light. Find the green wire that plugs on to the starter solenoid. See if your test light comes on when probing that wire's plug when you hit the start button. If it does and the starter makes no sound at all you've got at least starter solenoid problems and potentially the whole starter. It's rare for a starter to die all at once though.
If the green wire never gets hot that solenoid is your next thing back upstream to check. You'll find the same green wire there. See if it gets hot coming out of the solenoid when you hit the starter button. If it did not down at the starter it shouldn't up at the relay. If it does you've got a simple broken wire between the solenoid and the relay.
If the green wire doesn't get hot when you push the button you're checking more. The other wires on the relay will be a wire that's hot anytime the ignition switch is on. Just one like that. See if you find one. Another that is NOT green that is only hot when you push the starter switch. That's the one that comes from the handlebar switch and triggers the relay. If you don't have one that behaves that way your problem is likely up at the handlebar switch.
The other wire in the relay will be its ground wire. So you should have one that never gets hot. Ain't troubleshooting fun?
Twolanerider:
The diagram that is circled is on your relay and actually shows how it works -- which legs do which. So if you want to get a little deeper in the weeds you can use that. You can know of its working or not though by doing as we discussed previously though.
One wire hot all the time the switch is on.
One wire that is not green that is hot when you hit the starter button (if you unplug the connector from the relay it will only be this way).
The green wire hot when you hit the starter button but the connector must be plugged in to the relay.
And the ground wire.
Look for those behaviors and you'll have a good idea of what's going on.

The starter does not engage just the simple click from the relay. I will follow your lead and do some testing. I did wash bike then it didnt start, do you think something got wet that caused it?

Could have? Sure. Still need to troubleshoot to find out what though. Always do it easiest/cheapest first for troubleshooting though. It's too easy to get deep in the weeds; especially when it's something we may not be absolutely familiar with.
Did you have the side covers off for the bike wash? If so that makes it easier to consider a relay as problem. Soak the bike really heavy up around the handlebars? If so maybe think about the switch more. Though the "click" downstream suggests against the switch. Fortunately this is a pretty easy and obvious system to troubleshoot though. So long as it's not the starter itself all the parts are relatively inexpensive and easy to swap too. So grab a test light and just make sure you don't stick your finger :drink: !!

Over the years I’ve replaced my relay several times. As stated they simply wear out.
