"red one goes to the 47uf tweeter capacitor "
Which is probably 4.7µF, not 47.
The photo quality is a bit low, but it looks like the bulbs are installed before the horn pad, which is wrong.
The caps are probably shot, I would consider replacing them.

I measured the caps with a capacitor meter and they read OK? But Ill change them anyway,I know these meters dont tell the full story! Yes that 47uf was a typo its 4.7uf and the other one is 10uf. Im pretty sure the bulbs are wired wrong because one wire (red) goes to the 4.7uf cap and the other goes to the 10uf cap? Ill probably get the speaker back during the week and Ill check out whats going on with it? Ill take some decent photos of the wiring and get back here with them.Your a goldmine of information djk and I really appreciate all your help. That video of the crossover lightshow was an eye opener.lol🙂

The value is not the issue, you need to measure the ESR.
"The reason this crossover is being worked on is that there was no output from the HF. These speakers were made from 1994 to 1996, so this cap is 14 to 16 years old. It is supposed to be a 4.25uF cap, probably mylar. You can see that capacitance is off a bit, about 6 percent, but look at the ESR. 405 ohms!!
Nothing was going to get through this cap. "

Ive been meaning to get one of those but Ive always been turned off by the price.The one in the photo looks pretty expensive? (edit)Ive just had a look on fleabay,they have come down in price I can get one for $50 from China these days!
