Technical Fiat Ducato 130 m jet Radio attempting to come on when vehicle locked

[PaulR387]

I have a Fiat 2008 Ducato 130 multi jet Motorhome X250 and just recently the battery went flat down to 4 V, I did a current drain test reading only 60 ma which is acceptable so I changed the battery thinking that was faulty, today whilst working outside I could hear all this banging coming from inside the Motorhome, the noise was coming from the speakers with the radio attempting to play, I suspect that this is the cause of my battery being flat in the first place, my plan is to remove the constant 12 V feed to the radio and make it a switched feed as I’m not bothered about saved radio stations, has anybody encountered this? thanks

Hello,

The x250 is known for electric problems due to water ingress into the engine bay, the looms etc. Grounding points and cables tend to rust... So those are the first points to check.

I've seen several threads (not only here) about electrics / electronics doing strange things, had myself a couple of times a flat battery (old one and the new one, too) without a cause

Are there any errors on MES? shorts to ground?

Hi Green Vamper, thanks for the help, think I found it, chaffed wire shorting to ground in the radio housing, to prevent any more issues I’ve removed the permanent feed to the radio and now off switched ignition positive, regards, Paul.
