2007 haley lowrider wont start when you turn on ignition the turn signals just blink. think its the anti theft lights

SOURCE: 2007 sporster turn signals flasher , bike wont start

He's right! The key fob for the security system needs a clear signal to the module to disarm the bike. That's why the flashers turn on. If the fob is at the bike, the security module has lost it's memory, or the antenna for the key fob reception is not connected. You also need to squeeze the clutch lever to allow the engine to engage also...new safety feature i think for 07. Hope this helps.

sounds like the bulb in the rear one has blown and needs replacing.

Hi, technically i'd have you to to first of all trace the circuit to learn what's causing the problem before contemplating on a new module and using a multi meter to run the test as intended by you is a good idea. That will determine the condition of the turn signal switch and contacts.

A tip about how the Turn signal works....

The way the turn signals on your bike work is what is known as "Cheap and Nasty".
All the manufacturers do it this way. The resistance in the turn signal circuit is acutally very important to how they work. When you set the indicator switch to turn, you make a contact in the handlebar switch, and this provides either power, or a ground to the indicator relay. This is usually a three terminal device located conveniently where you can't get at it. The relay picks up, and this provides power through the relay coil to both front and rear indicator lamps. (Turn signals for the US residents.) The current drawn by the bulbs in the indicators heats up a bi-metal strip in the relay, and when it gets hot enough, it bends the moving relay contact that is providing power to the bulbs away from the fixed contact and the bulbs go out.
This bi-metal strip then cools down. It contracts and the moving contact makes the circuit with the fixed contact and the bulbs come on again. And so on. So the lights flash. And will continue to do so until you remove the power or gound from the input to the relay.
