Hi
Can I jump in on this topic, please. I have jut finished restoring a 1969 Lightning and thought indicators would be good in modern traffic. As per
usual, the ignition is positive earth, however I have done a separate circuit for the lights which is negative earth so I can have small LED flashers.
The problem is the flashers work perfectly without the motor running, but very erratically when the motor is running. Voltage to the flasher unit is 13.4 with the motor off, and the same when the motor is running. I am using a 3 pin flasher unit that is supposed to be ok for LEDs.
Any advice would be most appreciated.
Thanks
John
