Hot Rods Turn signal woes

How do you trouble shoot turn signals?
GM colunm, LED signals, led flasher. 4 ways work. Signals light but don't flash. Everything is new.

 

maybe your LED's aren't drawing enough current through the flasher unit?
try adding a globe to one side, if it starts flashing you could add a globe to each side (hidden away) to load the can up, or get a Dakota Digital no load flasher can.

 

I was thinking that too. 4 leds will flash but two wont.

 

Load up the flasher with a 1k 1/4w resistor and see if this fixes the problem. Try the 1K resistor at the left front (or rear) led wire to ground. If it works then install another 1K on the right side.

 

I'll try the resistors tommorrow. I paralleled a incandesent light with the led and they work. The leds came with a flasher with a ground wire that was supposed to make them work.
