my xr3i isnt charging the battery its not the alternator any help??

 

is the charging warning light lit when ignition is switched on? Does it go out when the engine is running? What voltage do you get measured across the battery when the engine is running?

 

had similar problem on my old 3i. turned out to be a bad earth.

 

light stays on wen the engines running. have no volt-meter to get the battery reading. took the eart off the alternator and cleaaned all the ends but still no joy
how you get your bad earth problem sorted?

 

if the light comes on with ignition and stays on, then it IS an alternator problem.

 

Thanks for the help. much appreciated

 

basically did what you did. Cleaned the earths and noticed that some of the smaller brown wires earthed to the body werent connected so crimped some new ones. Would imagine those small brown ones were a co-incidence but still like to think it worked lol

I did change alternator too!

 

i had the same fault when i had an xr3 1t was a bad corroded wire on the battery live terminal

 

put the meter cross the battery today and it dropped wen i started the car so guna get a new alternator well reconditioned one

 

sorry to bring this back up

my battery light is glowin and my window wipers come on themselves,ive changed bat and alt twice and still no change,cleaned up all known earths,still no change,any ideas?

 

hutchyotb, i hope you get this before you get a recon alternator, check the thin blue wire running to the alternator first, could be as simpleas that being broken

AND if its not that, it will cost about Ł20 to fix your old alternator, much cheaper than paying Ł100+ for a new one

 

As the Chav said...check out the blue wire....it runs along the front subframe up to the starter motor and is very common to fail. The amount of fiestas/orions/escorts that the likes of the AA and RAC used to bring into me for alternator or batteries that they had diagnosed that only needed a minor repair to said blue wire If onyl it was as simple as that on modern stuff eh

 

thanks for the help got it goin eventually then to my horror the guy who had the car before me didnt tighten a head bolt dont really need to say no more but after all the bother i can say it was worth it
