13v when warm

[tommycon45]

hiya
as any1 else had this problem?
when start the car i`m getting 14v but 5 mins later when its warm it drops down to 13v, i had a eco which used to drop down to 11v until in temper i banged the fuse panel and every thing went back to normal tried banging this 1 with no result, don`t want to hit it any harder, ha ha.

yeah mine seems to be at 14v when cold and drops when it gets warmer....

mine is a 95 turbo

around 13-13.5v when warm sometimes even 12.8-9 when some stuffs on like heated seats, demister, blower

don`t make any differance if i rev the balls off it when its warm it still only gives out 13v max. tested it at the battery aswel and still only 13v. the eco i owned give 14v at the battery and 12v-13v on the in car voltmeter until i hit the fuse panel the 1 time.

well if its 13 under load it doesnt really matter does it. if its dropping below the standing voltage of the system with only medium load then start to worry [img]/smile.gif[/img]

put a volt meter across a good battery & providing the alternator is good you should get 13.5 / 14 volts on tickover ,so i thought . any less especially at higher revs one of them is on its way out or breaking down somewhere ...

13v sounds about right.

not realy a problem at the moment for me but come winter when have lights, heated window and the blower on its not gona charge my battery. No good havin a calibra turbo that won`t start, LOL. i`l do another check tomorrow with the dig meter.
thanks for your input lads.
on a completely different note just watched NEWS on telly and there was cctv footage of 3 lads stabbing 2 other lads and they shot off in a blue calibra!!!!!!!

Mine does the same starts on 14v and after 5-10 mins drops a touch when warm. I was worried until I read this thread.

If the battery was overcharging wouldnt the engine management light come on?

14v is a healthy charge for a 12v battery, (with all lights , heated seats windows etc off) ... i drive a truck which is 24v the meter reads a healthy charge of approx 27v.... you must be putting more in than your taking out ...

Bleedin'ell..i've seen mine drop to 8!!! believe it or not and not with loads of ice..seems to have a mind of its own..will show 14 when started, especially on a cold morning..then hover around the 12 mark?
