AS LONG AS ITS NOT ****ING WALES!!!!
Is there a way of turning it off before exiting the car??? I am one of these folk who always turns everything electrical OFF in my cars before getting out and locking them up.

I have noticed the fan speed rotating dial on mine is a bit dicky in that i can only turn it down to speed 1 and no lower. It will increase in speed fine and back down again albeit after a few turns so i suspect it has a issue albeit is still working.

I was just wondering if this being on speed 1 all the time it could be part of the battery drain over night problem i think i have?? and are they prone to playing up??

Cheers in advance. Brendan ( Swindon )

this is normal, there is no 'off'

That’s interesting, I can turn mine off by turning the dial all the way to the left. That having been said, the spares truck you can’t, 1 is as low as it goes. Perhaps it depends on the HEVAC unit installed. The one you can turn off has heated seats and screen, the one you can’t doesn’t.

I was just wondering and the dealer who sold me the car said he fitted a brand new battery which after 1 week went duff on me. I have fitted a new battery and connected my C-Tek to it to keep it fully charged. Yesterday i disconnected it to start up and after playing around with the car for about 15 mins i noticed the C-Tek cable change from green status to amber so i started the car up and it changed to green again.
I have put my avo metre on it and the battery is kicking out well over 13 volts and more when the engine is running so i sort of tells me that the system is ok and charging. Obviously the car is not being run properly at the moment due to this rough running issue i have so no proper alternating charge being pumped in as yet so maybe its just me or a minor gremlin. Again P38 ownership is all new to me still albeit i am learning fast. LOL.

May be i am just reading too much in to things on here and other sites which give alot of info regarding these vehicles. The only way i suppose to know for sure if i do have an overnight battery drain is to unplug the C-Tek and see what it shows next morning.

the alternator should ideally be putting out over 14 volts to keep a modern battery healthy, alternators that havent been upgraded will push out a max of 13.8 which isn't enough. a new battery should read 12.7-12.8v with the engine off, ideally check it after an hour of sitting

have you started a thread about the rough running?

Marty does refurb kits and in the Technical Section he's done a post woth all the different types fitted. The dial acting up seems to be common although mine's always been fine - probably because I never touch it.

Sounds like you need to change the voltage regulator for one with a 14.7 set point. Simple job ,try thr search option the answer is there.;)

As each battery cell is 2.2 volts after standing a while after charge or switching engine off standing charge reading should be 12.6 volts.;)

But...But...But... that would mean a 12Volt battery was really 13.2Volts. It's a scandal, someone should say something....Oh.
