Vespa indicator problems

[Modlife]

Hi,
Does anyone know what causes my indicators to stop working whilst the engine is revving high.
They work fine when the scooter is on tick over. My first thought was a problem with the voltage regulator, but I have since changed this and still have the same problem, I have also changed the flasher unit which made no difference.
Any thoughts would be appreciated.
Thanks

Have you checked the sidepanel spring clips and frame catches are free from rust and have a good metal to metal contact? That's what provides the earthing for you indicators, I had the same problem on mine, I sanded down the clips and catch and now they work perfectly.

Also check the wiring at the back of the switch.

Have a look at the indicator earths in the toolbox as well. I attached them to another point and that solved a similar problem that I was having

All the above is good indicator problem areas, there not much else...
