Strange Boss DD3 Issue

[Guybrush]

Hi all

My friend has just brought round his Boss DD3 and it's got a really strange problem.

When it's plugged in on it's own there is no sound bypass or otherwise other than a fast ticking noise.

When it's daisychained and plugged in alongside other pedals the same thing happens plus all the other pedals LEDs turn off or flash and the pedals don't work.

Anyone any ideas on what the issue might be? It's got me baffled. 

Thanks.

Internal Shortcut in the boss pedal ? Power supply that is ?

Ground short. We're the jacks or school adapter recently replaced?

Hmm... I'll have another look tonight but everything seemed as it should jack wise.

Excuse my ignorance but what is a school adapter?

Cheers!
