SFBS, and Yes, I'm another 'victim' of Subaru's poorly designed electrical system. I got a "you want to go somewhere, well not today Mate" from the car this morning. The battery was showing only 4 volts and Yes, it was partly my fault for leaving an interior light on, but come on, should a car with so much electrical equipment & stop/start be fitted with only a 65Ahr battery as standard?
And given the car has so many safety systems on it that protect the driver from themselves, why use an incandescent bulb for the interior light (which might be left on by accident) when a low power LED would have been more suitable. This circuit should be timed to be switched off sometime after shutdown - I can't see any reason why the interior light would want to be left on in a locked car (other than by accident).
On the binnacle on top of the dashboard it is possible to display some useful info like Water Temperature, Oil Temperature and Average Speed . . . . Average Speed!! really? how useful is that, why not a Voltmeter given the car has so much electrical/electronic stuff on it??
Anyway I'm going to fit a voltmeter in one of the redundant cup holders (I don't drink and drive) in the centre consol - it will be powered from the nearby accessory socket. I've checked that power is removed from this when the car is switched off.
While I'm on the subject of electrics, why can't you default off the stop/start system?
Rant over . . . . 'til the next time . . . 😉
