Vespa px wiring

[ducksta]

Just finishing a Px 125 build
Standard px wiring loom no battery fitted, problem I have is I get rear lights front lights horn only when the red from the indicator relay is pulled off, if the red is connected the rear and front lights flash, nothing comming out of indicators, obviously I have some thing wrong but stumped at present.

Any help appreciated

what colours you got at flasher unit and how many wires ?

Red white green/grey

could be a poor earth in the headset. this may allow the feed to return through the flasher unit. take a single wire from engine and fix to good earth in headset then try again....
