So I've got my new iCarsoft plugged in, and as my stop/start eco has never gone green, I thought I'd check it out. (I am fully aware however, that if I do get it working I will probably be cursing it, but I'm a bit OCD and trying to get no faults!)
All perameters are met, except "On-board electrical system" showing "Not OK"
Car not started for a week, Battery voltage = 12.00V
Car running for 5 mins, Battery voltage = 14.7V
Stop engine & test, Battery voltage = 12.44v
Connected battery charger to small battery (original one?) in boot, showing 14.6V and so will not charge it.
Connected battery cherger to big battery (only 3 years old) under bonnet, showing 12.9v (and I've left it charging)
I'll leave it to fully charge and then try again, but the car does do monthly 300 mile drives each way up and down the M4 (and beyond) fortnightly and it stays amber when I'd expect battery to be fully charged so not sure it'll be any different.
Would a battery have any other issues not showing from these tests do you think?
Thanks.
