Crossover help?

Hi to all I'm hoping someone might be able to help.

I've tried to upgrade components within my crossover and now have no HF signal.

The tweeter checks out.

I've searched for bad joints , shorts etc but can find nothing obvious.

Today I've pulled the upgraded components from the Hf circuit but still have nothing.

Using a continuity test its all good up to the main cap and after back to the terminal.

I do get a bleep from both terminals so assume thats the parallel resistor.

I'm at a loss as to why its gone completely dead.

Anyone got ideas how to check the network front to back with only a basic multimeter?

Thanks in advance if someone has some ideas

Regards Ian

Maybe something like a frayed strand of wire or solder splatter creating an intermittent short.

Could you post some photos? Or a schematic of the original crossover? We can figure this out with just a multimeter.
