2004 CH80 - No dash lights but turn signals work

[RC4G]

2004 Honda CH80

Scooter runs great but none of the dash indicator lights work:
No HI beam indicator light even though HI beam switch works
No turn signal indicator light when turn signals are flashing
No oil light on key on

Horn, headlight, turn signal and tail lights all work fine

Fuel gauge does not work but I think the sending unit is faulty (need to check the resistance).

I have a service manual but the diagnostic paths for anything electrical all start with verify the turn signals work to check battery circuit (my turn signals flash fine).

I can't believe all the dash bulbs and indicators bulbs all failed simultaneously so where should I start?

OK, checked the harness connections behind the access panel in the trunk and for some reason the dash harness connector was loose.

Reconnected the harness and all dash indicator lights fully restored.

Also checked resistance on fuel gauge sending unit and no variance at all up or down which means it needs to be replaced.
