Title: alternator removal on a 2 facelift
Post by: rikki_essex on 31 December 2014, 14:52:53
Good afternoon all I've just bought my car and I left it for a few days without starting it and went to start it and it wouldn't fire. So I jumped started and it run fine but I did notice before that when everything was on ie heaters lights and everything else the battery light would come on albeit dim my next door neighbour has put a meter on it and thinks it might be the alternator lucky enough there is a guy that repairs them that live a couple miles down the road but I think he only accepts them once they have been taken out is it a big job to get it out and there is also all the lpg stuff under the bonnet

Have a read of Kevin Woods' excellent guide for testing battery/alternator, follow it to the letter and report back :y

Thank you very much for that I havnt seen that guide before but it does point towards the alternator as it drop below 13 under load. Is it a pig to get the alternator out

Not removed one personally, but with the front multiram ducting removed, access isn't too bad...although the upper mounting bolts are apparently fiddly to get at :-\

Much easier to remove an alternator from a 2 litre than from a V6. Haynes describes it well enough. Just note where the bracket below th alternator goes, in order to facilitate reassembly.

I think I have found the source of the battery drain as I was reading up why I couldn't sync all my contacts to the parrot system and it should say goodbye when the car is switched off. Mine didnt but there was very simple instructions online to just swap the red and orange cable over and that sorted it. Hopefully I now only have the alternator to swap over and it should be sorted.

Also check the battery terminals are not getting hot when a lot of things are switched on.
The crimped joints can fail, mainly the + terminal, goes high resistance and causes the alternator lamp to come on faintly. Could only see mine at night. The easiest way to find it is heat from the terminal, or check with a meter for resistance.
Worth checking before changing the alternator.
Hope this helps and not hinders.

Thanks for the advice after getting to work i turned on everything i could think of on and felt the battery terminal to see if they where hot. The negative terminal was warm but not hot but i put my finger on the positive and it burnt my hand would this just be the connector or could it be something else

Wondering...At what 2 points..One being the + terminal And the other being ?

It will be the crimped connection between the cable (red), and the battery terminal. No need to check for resistance, you have found the fault. Could also be the connection between the terminal and battery post, check it and clean it. But I doubt it is the problem.
I sorted mine with a new terminal. One with a couple of huge screws to clamp the cable. eBay I think. In car entertainment sellers seem to do them.
Not as straight forward as it sounds as there was no slack in the cable to reach the new terminal, after cutting off the old one. Had to extend it.
Sorry about burning your hand mate.

lol i should of thought about it to be honest and thank you for your help i will try and change it when i get a minute. How did you extend the cable?

Got a piece of battery cable, the right thickness, and a brass joining connector with screw terminals. Only needed extending an inch or two. Then shrink wrapped the connector a few times.
Did this a few years ago on my old 2 litre. Still ok to this day!
But very sick in other ways, unfortunately.
