Hi,
It's a 1.6 90 cabrio.
A few days ago, the battery light came OFF.
It wouldn't light up when in switch or when starting the engine.
Voltage dropped off when driving from 14v, to 13, and a few hours ago to 12v.
Then it after 20 min driving it dropped off to 10V and I couldn't start the engine.
I changed the battery to another, and still voltage wouldn't increase from 12V.
My alternator was rebuilt 3 years ago, but battery light was ON all the time, so I knew there was a problem.
I took the black cable from the alternator and connected it to earth, to check the battery light and it came on (Voltage regulator problem?)
I think my voltage regulator is original and wasn't replaced when I gave the alternator to a refurbish since he didn't have spares.
It's a marelli with a denso kind of thing that looks like a small battery.
I want to replace that part before I change the alternator.
I searched on ebay and came across 2 numbers:
9948730 - looks the same with marelli kind of battery
85563051 - looks the same with denso kind of battery
Which part do I need?
