1995 2.0 Knackered Alternator??? - DJDez1970

Hi,

New user to this forum.

I have an M plate 1995 2.0 GLS 16v 5dr Cavvy.

Friday nite, most of the warning lights came on, on the dash. Then the headlights when dim, then the engine wouldn't hold a constant rev. Nursed the car home, switched off, tried starting it again, nothing, no lights, dead as, a dead thing!

Having limited auto electrical knowledge, my first course of action was to change the battery. Put it on yesterday, put a multimeter across the terminals with the motor running. The voltage peaked at 18.8 volts!!!!!! Surely that's not right??? Also when I tried to take a reading with the heater, heated rear window, lights etc. Both headlight bulbs blew.

So, if you haven't all knodded off by now! Does anyone have any idea as to whether this engine has regulator/rectifier like a motorbike, or is my alternator knackered, or maybe something much more sinister???!!!!!!

Help me Obi Wan...
