Hi Everyone!!
I need some serious advice please
History: The Car was working fine and there was no electrical problems
Had to repair the alternator / PAS mounting bracket and after putting it all together I accidentally put the battery warning light cable onto the W terminal and it did not show charging voltage when we started up. it did fluctuate between 12v to 14.2V .... realizing something was wrong i checked the cable and corrected my error
Then i took the alternator apart and checked everything - regulator, stator and rotor and everything checked out with a fluke digital multimetre. we thought the only thing that could have blown was the voltage regulator and replaced that this evening...
and now we are even more confused as it will not go above 12.2v and will not charge
my Red battery charge light is constantly on.
Now: ......there looked like a slight fray in the battery charge light cable in the engine bay just before the alternator (it was only giving 1.4v on the volt meter) so i cut it and tested that i was now getting 12.4v to it and I even took the other end of the alternator and tested its resistance and it was fine i rejoined the cable back up and tested unconnected and and still got 12.4V
then tested that the alternator casing was earthed and it was with no resistance!
Took the battery cable off the alternator and off the battery and tested resistance and that was fine ( less than 1 ohm)
thinking we have solved the problem with it being the poor wire connection we put everything back together and founds ourselves back at sqaure one .... no charging and if i measure from the alternator case
When i put the volt meter on the battery light cable when it is connected to the alternator it only shows 1.4v
we are completely stumped here HELP!!!
