Hi!
My Cyrix - ct seems to be always connected to the starter battery (both batteries have always the same voltage). The 86 is connected to the - from the service battery and 30 and 87 to the + from service and starter battery respectively.
This morning I woke up and it looks like the service battery is getting energy from the starter battery even if the car is turned off. Is this possible? Both batteries are showing me the same voltage 12.4v. When I turn on the car, both batteries show almost the same voltage around 13.3 (service battery) and 13.4 starter battery.
Am I doing something wrong or did I misunderstood something?
Thanks!
