Hi,

Have just installed a Klaxon horn onto a 1914 Morris to get the authentic AWOOOGA sound. Have wired via a 12V relay with the high current side direct to the battery.


It works great when the engine is not running, but doesn't work when the engine is running. I think it may be something due to the interaction with the dynamo but can't figure out what may be happening.

Any thoughts?

Will
