Modern Vespa

Hi. I just experienced this strange power issue on my 2015 GTS300 super. The speedometer clock reset to 12:00 default everytime i turn off and on back the bike. No headlights including high beam. Can't power open the seat except doing it manually and no red light flash of IMMO when the bike is switched off.

Brought it to the dealer and found out one of the fuse is faulty. Work fine for few days then the same symptoms came on. Then send back to the dealer and found out headlamp relay is faulty. Then works fine for few hours then the same symptoms came back. Checked the battery health and it's at good 12V. Anyone know the solution to this? Thanks for the great help!

Did the dealer tell you which fuse was faulty?

Have you fully tested the battery, under load?

The dealer told it was the 15A fuse that was faulty. Mainly for the headlamp. Yes battery was fine even after under load.

there are several things on the 15amp fuse any of which could be shorting out and blowing the fuse. headlight (+switch), seat motor thing (+switch), cooling fan, accessories connector (eg alarm). each of these are via relays. disconnecting the plugs (behind the glove box) for each of these could help diagnose the problem

Yes. I agree. All of the components stated has a relay connected to the fuse. So far headlamp relay have been replaced with a new one the other day.

Currently the bike is with the dealership. Hopefully they'll get to rectify it. Thanks for the suggestion!
