hi all after reading the alternator problems on the other post i decided to get a new alternater today got it fitted what a pain to do any way when i turn the heated seats rear screen on my battery light still dimley lights up on tick over and gets brighter at 2000 rpm im going to get a new battery in the morn but could there be any thing else wrong before i go out and buy a new batt all the connections are fine
-
Can you test the voltage at the battery at all , the other thing to check are the earth connections to the car body . May be worth checking the battery terminals just in case :y
-
electric guys should come to the rescue but i would think its a earth fault have you tried running a seperate earth from the alternator i recently had trouble with mine and got expert advice it ended up after fitting new alternator it was the cable at the battery that needed recrimping
-
ok new batt fitted checked all wireing all ok still no diferent but i have noticed a wire that goes to the positive is getting warm is this normal cox this has got me beat
-
mine is hot too ( the wire that is ;) ) Im off to get another alternator tomorrow so hope that fixes it :o as Im having same problems as you.Does your battery go completely flat after a while? Why was it such a pain to change yours :-/
-
that the strange bit batt has never gone flat on me yet threason why it was a pain to fit is i live on a busy main road so i had to park my car the kerb edge it would have been a lot easier if i had a drive way and some ramps as somebody nicked em
-
Mine goes flat so sure its alternator, I live on country park so no road, traffic or people, just cows :D :D Im going in from the top so no need for ramps, diesel engine is easier to do than my petrol :y
-
that sounds like heaven no road no people bliss :D
-
It is heaven :y

ok new batt fitted checked all wireing all ok still no diferent but i have noticed a wire that goes to the positive is getting warm is this normal cox this has got me beat
Have you cheked and double checked the the earth from the engine to the body ...shoul be a fairly heafty cable just cos its tight and looks ok doesent nesecerily mean its a good earth ...seen this before
-
im going to go back over it it all to triple check i might have missed something
-
ok tried again today still no look but now altanater is not charging battery but the thick brown wire to the positive is gettin red hot the wire runs across the the front of the engine mine is a 2.6 v6 motor have i done something wrong or have i missed an earth strange bit is batt warning light isnt lighting up any more turn everything on and leave on tick over abs tc airbag lights start to flash multi meter says 14v everything on 11.4 help please im stumped i miss driving me elite :'(
sorry batt light comes on when ignition on then goes of when started
-
This wire often gets hot because the crimp into the battery terminal has become loose. Is this the case here?
The fix is to obtain a terminal with a screw clamp for the cable and re-make the conenction to the battery positive terminal - or replace the whole cable assembly with terminal.

this might sound thick does that wire go to the alt or the starter motor
-
it was my problem kevin after buying new alternator and having it fitted mechanic who origionaly said cable was ok found out that it was not after charge was still same at 13 volt grrrrr but i have new alternator on now mind he did say shall i take new one of and replace your old one but i thought possibly false economy but wish he would have checked more carefully i would take extra care with that cable if your charging rate is down
-
this might sound thick does that wire go to the alt or the starter motor
It goes to both.

hi all first of all thank you for your help every body it is really appreaciated :y
ok today i decided to to have another go with a a little help froma mate who knowes electricity just to go over my work to see if i had done something wrong before i started chopping wires any way we changed the positive terminal connection as suggested as this is what it was looking like to be the problem nope it was still getting hot so we checked it all again alt was fine batt was fine so again another check eventually we think we found the problem the earth strap that goes from the sump to the chassie wasnt earthing propperley even tho it was clean >:( so we decided to ad another earth from the engine houst bracket to the main earth point under the battery as a test problem went ;D so decided to leave it but i also put a new earth strap on sump to replace original so it has two earths up to now everything seems ok voltage is working as it should even with every thing on wire gets warm but not hot enough to burn your fingers so fingers crossed its sorted i have orderd a new cable from alt to battery just to be on the safe side again thank you for all your help guys :y
-
Fingers crossed your all sorted :y I hope when I finish changing mine tomorrow it doesnt turn out to be the cable :D I have had the battery on and off so many times lately I could well have damaged a cable or two :( :(
-
fingers crossed for you it hasent :y
-
ye glad sorted those cables need checking then double checking
