|
|
Hi, I have mk4 2007 and the alternator has the 4 pin connector but only 2 wires, is this normal?
Also, it was charging high at 15.8 volts, and frying batteries and battery light was on in dash, so purchased a new alternator (mk4, 4 pin) to hopefully fix the problem , and now it's charging at 18 to 19 volts !!!!!
Do you think it's a faulty new alternator, or should there be 4 wires at the socket not 2, and should the car regulate the voltage not the alternator?
Any ideas folks 😐 |

Output voltage should be around 14.4V and that is controlled BT the rectifier/regulator in the alternator. I think this is a replaceable part.
As for the wires I thought that each had a wire but couldn’t swear to it. |

Something strange here, brand new alternator fitted kicking out 18v , battery light on, and if I rev her I lose dash lights and abs light comes on, obviously because of over charge voltage.
Strange I only have 2 wires with a 4 pin connector, anyone any ideas please. Maybe I should buy a mk3 alternator and change the connector to a 2 pin. !?
Very strange 😮 |
