I dont understand why you'd need two flasher units
in fact cant recall ever seeing two flasher units on anything
bike car or truck
What bike?
The usual way they work on many bikes is
power in to flasher unit with ignition on
power out to indicator switch
thats it
Early bimetal and CR type flasher units usually have two
connections while later electronic units usually have three.
When the turn signal is put into either the L ot R position
the lamps/leds complete the circuit to ground and they should flash
A quick test is to put the switch into say the R position them jump the
flasher unit with powered flying lead on the output/switch cable
the R lights should all light brightly
Ditto switching to the Left.
If they do, suspect the flasher unit and/or connections/supply
If they dont, suspect the lamps/switch/wiring/connections/earthing
If a load resistor has been added,and its too low a value, it could short
much of the power to ground.That would dim the lamps.
