Flasher problems

[hphilbo]

Hello all,
Making good progress with my 1976 3 1/2 sport but I’m currently struggling with the indicators. They stopped working completely so I replaced the flasher relay with as close to like for like as I could find. With replacement relay fitted, the left hand side are flashing normally but right hand side are flashing too fast. There are a couple of previously installed choc block connectors in the circuit which I have re-made, the bulbs are all 21w. Any tips on what to check gratefully received.

Obviously connections and earths, but also consider (if not after originality) an LED electronic flasher relay that sends a regular 12V pulse to the switch regardless of load - a few pounds from a foreign land via a well known auction site..... needs a minor wiring tweak but has proved very reliable for me so far with consistent flash rate regardless of battery state, temperature and vibration.

Have you tried swapping the bulbs left and right to see if it moves across. Are the bulb contacts clean?
