hi guys, just bought a lupo a few months back and im in the process of mending everything that is wrong with it before i get it back on the road, im just after abit of advice really, ive rewired the rear speakers as the sound quality was terrible due to frayed cables and bad connections. i didnt find this too difficult but behind the head unit was a mass of connectors, taped connections, just a general mess really, after ive worked through the mess and figured out what he had done with the rats nest thats behind my head unit i turned the ignition on and my battery was totally flat and then when i turned the key back the off position the dials started to shake for a couple of seconds wondered if anybody has heard or seen this happen before? any help would be greatly appreciated cheers
