Re: Flat Battery Stereo Conflicts
Hi mate, i also have a '99' 156, and have started to find a few gremlins with the electrics.
With regards to the stereo, even if the stereo you fitted was working on a permenent feed, it should not have caused any problems as long as it was turned off at night or the facia panel had been taken off.
A fault i have just found on my 156 is that the rear interior light has started comming on randomly and the switch on the light itself wont turn it off, neither will the doors opening and shutting, it just decides to switch off after 10 or so mins. Check to see if yours is doing similar as this may be the problem.
If you think the battery is cream krackered, take it down to a halfords store and ask them to give you a battery test, this is free, when they do it ask them to explain what it is reading so you know if there trying to rip you off, and ask to see the reading.
