Hey guys
I have this ongoing problem with my VT 5 litre.
In the morning car starts ok. After about 5-10 minutes of driving charge rate drops to 11.9V. I replaced the alternator with a new Bosch unit and fitted a new Bosch 530CCA battery. Still no good. I heard they had problems burning out battery harnesses between battery and alternator. I ran a new thick cable from battery to alternator and still no good. I checked, cleaned and tightened all visible earths off battery -ve terminal and still no good. When cruising charge rate is around 13.5V. If allowed to idle for a couple minutes with slowly drop down to 11.9-12V again. This is with a brand new alternator.
What the hell is going on?! Is my external battery cable not good enough, do I need to replace the actual harness?
Does the engine have an earth strap around the back that goes to the body somewhere? I looked but couldnt find it, its the only one I havent checked and cleaned.
Thanks
Nick
