Modern Vespa

hello, new to this forum, this is my secobd post.
I bought a once stolen LX50. Wires were exposed, started though. I connected the rear ignition switch and finally got both the horn and indicators working. The indicators done work to well, they dont flicker like they shpuld. I'll try and post the video.
I was informed to check my battery as it could he bad. One recomendation to was to connect my car battery to my vespa and crank it that way.
My question with the vespa battery is, if i recharge it using a battery charger, will that return the battery to normal, or just go straight to connecting terminals to my car and trying the indicators that way?

Hi check your indicator relay and all wires and connectors, sometimes something silly like that.

The indicator relay is usually part of the regulator/rectifier.
