I won a horn auction on eBay a few days ago, and it turned up today.

I mucked around trying to give it a blast, but I don't have a power supply big enough.

I thought I could use the 5amp power supply I've got, which I lent dad to charge the car with a few days ago, but it doesn't seem to work.. I opened it, and the components between the transformer and the terminals have blown up (don't remember if they were diodes or caps or something).

I tried running it off a 2amp supply, but it just warbled.

I gave up in the end, and grabbed the SLA battery out of my bike, and gave it a blast.

My god, it's the loudest thing I've ever heard.

Now I have to find a way to fit it to my bike, I think it will fit in the front, behind the wheel.
