As I work through the issues on a new acquired 04 plate CDTi saloon (with under bonnet pump)
I now find the alternator charges around 13.2 volts which goes down to 12.2 volts when loaded by headlights, heated windscreens and heater fan.
A parasitic drain test showed a problem with multimeter on 10 amp setting read 0.69. Should I assume this may well be the alternator? I took the easy to access coloured relay and fuses in the engine bay out and it did not affect the reading of 0.69. I could not find a tool to easily pull the 4 flat shaped low profile 50 amp to 100 amp fuses.
We know the diode on the alternator can cause fail and cause this kind of parasitic drain? But would changing the regulator/rectifier pack be a fix? Is changing the regulator/rectifier pack the best way to fix? Buy cheap from ebay for around £30? The car has only done 86k miles.
