[ROVERNET - UK] P6 oil pump

[Paul Smith]

1.  I measured some voltages.  The cutin points aren't cutting in, it
doesn't get enough voltage.  The genny output was 12v with 12v on the field
winding at 3000rpm, woefully low.
2.  More that Melbournians don't use speedos! Zoom...  Most of the trip was
100kmh driving.
3.  I will swap the sender as a first action, but have gut feel it is pump
due to slowish failure.

Paul, sorry to hear about your casualties.
1)The problem could also be the regulator. The workshop manual has a good 
section on troubleshooting both but you will need a voltmeter.
2) There are probably enough old P6's around that you can get the speedo 
angle drive. Are you saying you taxed the drive with excessively high 
revolutions??
3) The only sure way is with a pressure gauge. Don't know what the specs are

but it should certainly be above 5psi at idle. It'll be in the manual. Most 
oil lights come on at around 5 psi. It could also be the sender but you 
probably already know that.
Ron.
