MG TD TF 1500 - electrical question

Any advice on how to diagnose the following problem would be appreciated. 1954 tf, original wiring. the horn stopped working. checked the accessory fuse, it was burnt, replaced it, horn works now. however, when i replaced the fuse, the power came on as if i had turned the ignition key to on, but i hadn't. if i remove the accessory fuse, the ignition key functions normally. When i replace it, the fuel pump comes on and the car is ready to start even if the key is off. thoughts appreciated!

Check again to be certain that you placed the new fuse in the right location (A1 to A2). If the fuse is accidentaly placed 'between' the fuse clips you can create the condition that you're describing. Bud

Bud, that is always my back-up plan when I want to move the TD and too lazy to go in the house to fetch the key. Happen to discover this by mistake.
