Last year I got good advice here on how to set the relay cut out and all was fine until my CRV went to Honda for it's annual service 2 weeks ago. The dealer said the battery was low so it was put on charge during the service. About a week later starting seemed a bit sluggish I checked the voltage and it was 12.2. ( battery not long new and fitted by Honda as car has stop /start system).
I then checked the number 10 socket and found that the relay did not cut out until the voltage dropped to 12.28v at the battery.
So Is this draining my battery down as there is a parasitic drain, (previously detected prior to last year's reset)
Is the relay faulty, and
Finally should Inreplace the relay with one that is preset to cut in at 13.5v and cut out at 12.8v. Available from accessory shops online.
