All well and good Timpy- if I knew what I was testing and what I was looking for! I’ve had the crossover board out, which is fairly simple, but I don’t know how to test each component, what the value should be, plus I haven’t used a multimeter in over 20 years!
Sure we can help with that though Mr Neds. I'm no expert but basically the inductors are unlikely to have failed - so, so long as they have continuity when measured with a multimeter then they're probably ok. DC resistance for the inductors should be very low. Same with resistors, they should measure roughly the value on them. So they're both easy, and those bits are least likely to have gone wrong.
I'd start with the Capacitors, they will charge when connected to a multimeter, so if they start off as shorted, or stay open circuit, then they're your culprit. It's almost certainly one of these that is wrong, and as it is only the tweeter the doesn't work, yet the tweeter is good, you could probably just change them for little expense.
Or just post in the DIY section. I bet you'll be surprised how easy they are to repair.
