Hi guys, I know its been done to death but I have a problem with my rangie's battery going flat after a very short time.
99 Thor 4.6 HSE
I've had the car a year and to be honest it wasn't much of a problem for ages, however the battery was small and old and after 10 days or so it seemed to flatten it. The car never forgot the window settings or needed the EKA code or anything just sometimes needed a jump. (70ah battery)
Anyway I figured this was a weak battery so I bought the big mega 110Ah battery and put that in. It needed the EKA code that time, no problem got it all running. But it now seems worse than ever, I tried to use it yesterday and it had been 6 days since I had used it and it was flat (alarm LED still flashing) but wouldn't unlock on the fob and the message center showing key code lockout as soon as I unlocked the car. Almost every time this is flat i need to enter the EKA code which is very annoying especially as it never used to do it!
Other information SOMETIMES if you turn the ignition on but don't start the car it comes up with Alternator Fault on the message center. It always clears and I've never worried much about it because it manages to recharge the battery very quickly.
The problem is I don't actually use the car much or go very far in it, how long should it take to recharge the battery? The last time it was flat I did a 16 mile journey out of my way just to put some in it but it doesn't seem to have helped. Often the use I have for it is when Its got a job to do, or something to move and it isn't half annoying having to go through the messing about of jump starting and the eka code every time.
I was wondering is there a way of charging it through the tow bar electrics then I could just discreetly plug it in when its at home and keep it topped up?
I havn't checked the becm for battery drain issues but I have disconnected the RF aerial to try and help but it doesn't seem to have made much difference.
Whats the best way to test the new battery and alternator?
