CONFUSED.COM Flat battery

[littlemark]

Help guys

Went away to Stanford hall at the weekend with no problems, camped 2 nights, started Monday morning first time ( as always) travelled the 2 hours home, went to start 10 mins later and nothing. Check all the usual and everything ok. It turns over but sounds like battery is going flat. Anyway jumped started and runs normal.. went to start it today and nothing..

Nothing left on before you take the piss........

How old is the battery?
Guess you arent getting a battery light on whilst running? So the alternator is functioning?

 

[littlemark]

To be honest I don't know. I have had my bus almost 2 years and no to alternater the light coming on..

 

[StuF]

Sounds like it may be time for a fresh battery?
I went for a Yuasa 640HD 100ah and 900amps for cranking

 

[littlemark]

Cheers buddy. If it was the alternater am I right in say the light will be on....

Also worth cleaning the terminals, clamps and check the earth. I had an intermittent problem with not starting, would just get a click or nothing at all despite a newish battery. Cleaned everything up and not had an issue since

Yep if the alternator wasn't charging the battery the light would be on. It should light up when the ignition is on before starting the engine and then go out as soon as the engine fires up

 

[littlemark]

Yep thought as much cheers stuf...
Will have a clean up of the above mentioned..
Thanks all

Just looking at batteries myself, thats a beast you have there, I may follow suit!! I have just noticed my light stays on at idle but goes out when I increase revs, that does rule out an alternator fault doesn't it?

Cheers

Yep - mine sometimes does the same, especially when cold and not been run for a while. Small blip of the throttle and it goes out. Think it's just the voltage regulator clicking over

 

[CornishSilver]

Sweet, thanks for the quick reply mate. Pretty sure I just need a battery now

Just to second this, I had the same problem and a new earth strap to the engine/gearbox sorted it out

Not trying to teach anyone to suck eggs, but have you charged the battery up ? The battery is a reservoir of power, if you have camped with it for a weekend and used a bit of juice from it, then started an engine from it, then you may have virtually flattened the battery. A two hour run cannot charge a flat or almost flat battery, that's impossible. A brand new battery will have more power left in the reservoir also dependent on its capacity whereas a battery on its last legs will be easily used up or flattened. Sounds like this old battery may be struggling to keep up.

Ozziedog,,,,,,,, give it a good 24 hour charge first. :mrgreen:

Is it your battery?? Might be the starter needing a clean out.... just a thought

Well, if you want to play those games.....

 

[StuF]

Your main one is a whopper Sparky!

But you could try harder with the leisure :lol:





It just about fits!!

 

[sparkywig]

Mine is a 115Ah as well.

 

[littlemark]

Cheers ozziedog.
Battery always charged and has never done this before. I have a leisure battery for lights, music,water pump etc.. so i wouldn't of thought i used any juice. I am guessing the battery is gone but will charge it and clean all terminals just to be on the safe side..
Cheers
