Weird battery issue

[A80Avant]

Maybe that is why mine has been having issues if it has a regulator meant for greece its ok to be less than 14v as in greece you have a mean temp of 25-30c all year round!

Anyhow, I got a voltage regulator at 14.5V now so once here ill see how I will tackle things.

now remind me what I said on Saturday about alternators....

[A80Avant]

I don't remember. What did you say?

[europeanme]

I don't remember. What did you say?

overcharging alternator and how it made mine behave...ring any bells....

I know it was early!

[A80Avant]

You have to be more specific than that.!!

In my case it seems that 13.4v on the alternator is not enough. It should be as Andy's

"get your alternator checked out"...how specific is that!...

question, you had your discs changed, what about new pads?....

Doh! We did with Brian. Hence the 13.3xv which at the time we thought was ok.

Pads had been changed on a previous occasion recently

Remanufactured alternator came. The regulator had no inscriptions whatsoever so I replaced it with a 14.5v one, a bosch original part.

Fitting should be done on Monday.

Funilly enough the car has been starting when left over a week on the solar power screen. Not bad!!!

Update

Remanufactured alternator installed with a proper bosch voltage regulator as the one it came with wad of unknown origin.

Battery now reads 14.3V

My varta reconditioned went in reading 12.55v so that makes it close to being perfect.

So I hope now things are cured!

Thanks again for all the help guys!

My bosch alternator is going for a rebuild and staying on the shelf for the future

if you not shure of the charge ( volt) meshure the acid weight in the battery ( 1,275-1,280 are ok) lower than that 1,24-1,25 = half charget battery...14,3 volt; did you tryed With the lights an heater on, by the ca 2000 rpm( hold it in 60sek or so)....14,4volt by the 2000rpm are ok with lights on.

[A80Avant]

No. Will to that as well. Thanks

By the way the 14.3 is on the battery not the alternator so judging by Andyp measurements that's better.

I used a 14.5 voltage regulator not a variable or a 15v one. Also while I checked that alternator and battery were similar bolts previously on idle I suspect that I don't have any significant losses from the cable. Hope its ok

[A80Avant]

Just checked after the engine was hot, with front screen heating element on and radiator fans on was reading 13.9V at the battery on idle, 920rpm.

I couldn't check anything else as its started pouring for good.

meshure the battery acid weight.... 13,9 v -its TOO low....!!!!!

[A80Avant]

Sorry but to do that I have to buy a hydrometer and dismantle the sealed battery to measure the internal liquids of it?

Is that cheap?

[caterpillar]

some battery does have a sticker over the sealed topp, so you have to take this off, some cant take the top of... so you need to check this ... have safety goggels, and gloves on...!!!!
the hydrometer from a cheap car chop dont cost a lot( max 5$, or so)( floater weight unit)..you have expensive versons too... the cheap ones do the job, for shure
