do you have a multy meter??????

 

no unfortnately i havnt, but wat do u think it might be at a guess? cheers 4 the reply m8

ps. my alarm works off the fob nice an loud so i dont think i need a new battery unless its got its own back up??

 

battery is shagged mate.

 

sounds to me the battery is not holding charge or the altanator is not charging or over charging and knackerd your batt!!!

if you can get hold of a multi meter from some where it would help alot....
because i need you to check the charge rate....once we know what its charging at i can tell you what the problem is by the volt reading.

 

hay mister you should never condem anything intill you know for sure you bugger....

 

cheers lads will go garage in mornin an get a reading if i got time b4 i go 2 work
dont fancy drivin my gf's 1.4 clio

 

I'd say it's lost charge through the loose lead. . now the battery's flat and its not had a chance to charge from just leaving it running for a short period.

I'd bet my bollcocks on it.....

It it's electrics are working while engine is runnint, then current id coming from alternaotor. If they dont work when engine is off, it HAS to be the battery. If it is that flat due to charging issues, it is now shafted.

 

my battery's been drained beyond belief countless times and it still takes and holds a charge

 

but what if the surpressor has a winding problem in the altanator and creating an open circuit which will give more than the normal ampage of about 1.50 amps to a high 3.0 or 4.0 amp thus creating the drain as it is ignition fed.... anything is possible on a car.....

 

sorry permantly fed.......

 

the alternator charge current would overcome it for a short period of time.

 

Alternators dont operate fully until something like 3500Rpm? so if it was sitting idling on a drive. . it wouldnt charge the battery, and depending on how flat the battery was, it could take even longer to start giving it charge!

cheers lads, i bumped it again this morning, got it started then took it 4 a drive, parked up turned it off an bk on an it starts off key now, must of bin the loose bolt on the battery, suprised as it was only loose a couple of turns, must of charged bk up wen i drove it about, once again nice one lads
will go garage monday mornin jus 4 peice of mind

 

Ok, so I got the charging RPM wrong. . I was told off a mechanic but everything else I wrote was correct. . .shafted battery did you say rick?
