I've had a fault recently on my transit mk6. if i braked while indicating right the indicator would go like the clappers. it has pregressively gotten worse so i had my suspicion it was the back list bulb holder or connection. Although the bulb holder seemed ok the connection plug has welded itself on. bought a new bulb holder and got a plug from the scrappy along with a choc block to wire it up tomorrow. My question is do i need to disconnect the battery before i cut the wires one by one and reconnect via the choc block,

As long as the Ignition is off along the light switch,Youll be fine worst case senario youll blow a fuse or if you have the radio code disconnect the battery ...

cheers, i just thought id check before getting a belt off anything.
