I finished wiring the electric fans on my P38 so that I can turn them on manually. Might be helpful if I have to do a long and slow uphill climb in hot weather. Last year I installed an Autometer water temp gauge so that I can better monitor engine temps.
That's the ticket, a few months of Rangie ownership and the dash is starting to look like KITT with LEDs and monitoring for everything. If I hear something resonate differently after going over a bump I have the bonnet up and my stethoscope out and tapping. I'm a bl**dy nervous wreck.
No, Dopey started it 855 pages ago!

Maybe his laptop playing up again
checked the battery this afternoon, 9.5v 
whizzed the engine over nice and quick when I used it at the weekend! Not impressed
put it on charge, threatened it with one of these;

CCA is only 870, not enough for a diesel and it's dearer than the MF31-1000checked the battery this afternoon, 9.5v

870 was the biggest they dofound this, assume you know it fits https://www.batterymegastore.co.uk/product/hankook-heavy-duty-commercial-battery-mf31-1000/

Yes it fits, I have 2 in P38's, 2 other HANKOOK in my Transit, 1 in the MR2 and 1 in my lawnmower. No complaints.mines a proper petrol engine

The voltage at the OBD port is always lower than actual battery voltage.
I have just discovered that some regulators do indeed back off when the battery is fully charged. I'll do a post about it.
you're right, it will always be lower, but its a rough guide.
I'm just not sure my alternator is dying, or working properly

I fitted voltmeter/usb sockets in both P38's so I can monitor voltage.
Normally the original regulator in the P38 put out a constant 13.8 volts, modern batteries need more, on my Transit it's 14.7 volts, both are constant voltages. However the Mobiletron VR-VW010 regulator appears to be a smart regulator, immediately after starting, I see 14.6 volts dropping on a long run in the car to13.2volts which is a float charge level for a fully charged battery.
my alternator doesnt look new by any standard, but its new enough to push out more than 13.8v
bit of a surprise to the a dead battery today given it was full of beans a few days ago, maybe something has given up inside, it wasn't the most expensive battery when i bought it

I had a battery fail on the P38 a few years back, got home from shopping all OK, got a call to go to the airport an hour or so later and it was as dead as a dodo.
