Hi,
I purchased a used Prado recently and noticed there is a disconnected cable from the dual battery isolator. I think the cable supposes to connect to the starting battery +terminal but it doesn't. The other wire from the isolator leads to the back of the vehicle and I'm not sure where it goes to. I think it was setup that way for the 2nd battery in the trailer because I know the previous owner had a trailer.
When I connect the mentioned cable to the +terminal of the main battery, I see the charge light of the isolator turned on which make me very confused because I don't think there is a 2nd battery on the car at that time.
Could anyone please tell me what's going on?
The voltage when unplugged is 12.27v, when i connect the isolator wire to the battery it drops to 12.24v. The engine was not running at the time i checked.
