Put the new battery on, so will see how the Bus fares with this one. Super heavy duty according to the label with a 5 year guarantee.
Took the engine shroud off and had a look at the choke mechanism as it doesn't make much difference when the cold start/choke lever is pulled. Sprayed it with WD40 and checked to see if the cable was opening the mechanism on the fuel pump. Everything was OK. There was a slight rev rise when the choke lever is pulled.

Battery is on the way out. Tested it again with the multimeter and a reading of 11.88 was shown. This represents a low battery, 10.50 being flat and 12.70 being fully charged. Although 11.88 doesn't seem like much of a drop, in reality the battery has only about 30% power (max) . Priced a few batteries up and will buy a new one and fit it on Wednesday. Also will buy some heavy duty jump leads, you never know when you might need some. Haven't checked the power from the Alternator though, but I am pretty sure it's the battery that is on it's last legs.
To test a 12v battery's charge or voltage, make sure that the battery has not been charged for at least 2 hours. Turn the multimeters dial to 20volts DC (batteries are DC mains is AC) put the red cable into the Volt/Ohm socket on the multimeter and the black cable into the Com socket. (Com means Common or Earth/Neutral). Now place the red tester onto the + positive terminal of the battery and the black tester onto the - Neutral terminal, read off the numbers on the multimeter.

Well, the cold weather and dark nights are here and this is having an affect on the battery. The Bus didn't really want to start yesterday morning. Took the battery off and connected it up to a battery charger and the ammeter displayed 3.5 Charged it up for 6 hours and there was hardly any change. No bubbles rising or anything. Will take it to the local Carparts shop for them to test it. The battery was bought used off a Mercedes Sprinter last June.

Down to North Yorkshire last weekend. Drove down on Friday and spent the weekend at the farm finishing off the willow fence. Rainy on the Saturday but beautiful on the Sunday, nice drive home on the Monday. Stopped off for chips (poor) at Masham on the way back, you just can't get a good bag of chips anywhere these days.
