Yep.
If the wiring looks / tests good, go through the connections. Use contact cleaner if you can lay your hands on some, bit of wet & dry on all the contacts you can get to, otherwise unplug and replug everything a few times. Don't forget the earth connection. The wires might be fine, but if you've got massive resistance in the connectors, nothing is going to work, and relays / solenoids not tripping is a good example of this - your electronic tester will tell you that you have 12V, but not the current you're getting. Remember, I = V/R, so if you have a lot of resistance you won't have enough current to trip the solenoid.
Your multimeter can be useful, though, at least for testing the switchgear -
rather than using a continuity check, do a resistance check. It should be infinite when the switch is not activated, and as close to zero as possible when activated. If not, dismantle the switch, contact cleaner, wet & dry, etc...
Electrics are a shit to debug, especially on bikes where you get a lot of shit and bugs in the electrics
