Right turn hand signal. To signal your intention to turn right, rest your left elbow on the windowsill and raise your forearm up so it forms a 90-degree angle with your arm. Keep your left hand open. To make a left-turn hand signal, act as if youâre physically blocking someone with your arm.
There are two relays in the flasher unit. I call them the master and the secondary relays. Here is a functional schematic of the flasher unit. When the turn signal is activated with the right hand side thumb switch the transistorized timer circuit in the flasher applies a pulsating signal to the master relay coil. This sends a current through the secondary relay coil as well as lighting up the signal lights on the motorcycle.
