I've been having some issues starting my 80 in the past few weeks even though it's had two new batteries in the last 6 months, both 95A/h Bosch ones.
After removing them both from the truck and charging for 24 hours each,the vehicle still won't start if left for more than a couple of days and needs to be jumped.
I've checked the following:
- Voltage across the batteries rises to about 14.4V when the truck is running so I assume that the alternator is charging them.
- Using an ammeter I checked the current drain when the vehicle was stopped and it was showing 400mA but I don't know if this is a lot.
- Removing the fuses one by one dropped that to 150mA when the seat motor fuse was out, again not sure if this is normal or not.
- Drivers side battery drops to around 4V whilst the passenger side one is up at 10 - 11V when I attempt to start the truck.
To me it looks like the drivers side battery is faulty but if anybody has any thoughts on the matter I'd like to hear.
