Constant battery drain - circuit F29 (interior lights, radio, etc.)

[matt hromadka]

Hi guys,
on my PH1 172 my battery won't last overnight unless I disconnect fuse F29 (interior lights, radio). There are no obvious issues (all lights turn off as does the radio when fuse is left in and car is locked. I would imagine I should be looking for a bad earth? Or can someone point me any other direction how to actually find out what exactly is draining the battery? Does anyone have a circuit diagram for this?
Also my reg plate light is not working (not bcs of bad bulb), but that should be a different circuit, correct?
Help much appreciated as I am not exactly an expert auto electrician, but would like to it myself.
Txs,
Matt

what current is it drawing when ignition is off?

Sorry, totally forgot I posted this and never replied. The battery drain is .75 Amps, when I remove the fuse for this circuit the drain .04 Amps. Any idea?

Matt, did you find the source of this drain on fuse 29?
I've got the same problem.

Hi Bowser, sorry for the really late reply. Just in case you are still having the same problem - I changed the battery and suddenly the drain is gone. I have no idea how this happened, but never happened again
