Refering to the attached results,the conclusion to solve the problem is to replace an alternator. I'll to see what i can do and i'll update you guys.
Ok, so new battery. You drive enough that the alternator should be able keep up the charge. There is only one thing you should do before you go and get a new or rebuilt alternator, test the voltage at the alternator. There is always a chance there is a bad wire/connector or something else in series with the alternator that is causing the voltage to be low at the battery. If the voltage at the alternator is below 13.5 V, it needs to be replaced. If you can check the field voltage that would be great too. If it less than 12V, also not good.

Normally shops don't rebuild your alternator. Normally rebuilts are done by a shop that tests them fully and are almost as good as new and much less expensive. Make sure you get a warranty on that part either way you go.

Where and how do i
1. test the voltage at the alternator? (All the readings i had been getting was from the terminals at the battery)
2. test the field voltage? I am not sure whether i could have a reading around 12V?

RE: Starting Failures *URGENT HELP NEEDED!!

So this is the voltage regulator and carbon brushes. Actually, the one in the picture is the old one that was removed 2 weeks ago. I am now using a new unit.

*By the way, how do you upload a pic in a new post?

Thanks Teky,

Do you know what is DTC B 1703?

Is it a faulty code of some kind?
