So.. The not charging issue came to an end..
I found out that the fusebox is not receiving 12v as its suppose to. Thus not able to provide suffocient voltage to activate the coil inside the voltage regulator..
I measured voltage from battery post to starter motor = 12.5V
Measured from battery post to fusebox = 3V (too much voltage drop)
Measured resistance from battery post to alternator B+ = 0.3ohms
Measured resistance from battery post to fusebox = 90+ ohms
So i traced the thick white wire..removed the insulation tape to see where it taps into..and i found out a heavily oxidized join, so i cut section by section until i see a good bare copper conductor. Gave it a good squirt of contact cleaner
Pull a new 8 Gauge cable from battery to the alternator B+ post. And join them back to the fusebox
Measured the resistance from battery post to alternator B+ = 0.2 ohms
Measured the resistance from battery post to fusebox = 0.3 ohms
Since then, i started the engine and it charges right up..measuring 14.5V across battery terminals..
Next is headlights wiring which altezzaclub has posted, and also tackling something funnier which is whenever i press the brakes, it turned on the cluster light..its following the brake light..
By the way. Just to share my ride on new wheels
