hi everyone,
Just hooked up my isolator and noticed that when using my accessory battery to pump my tyres that both batterries were dropping voltage at the same rate.
Is this supposed to happen up to a certain voltage (12) then they seperate?
(note the car was not running)
If so then that means the batteries are in parrallel? yes/no? I thought the isolator was for charging and keeps the batteries seperate.
Thanks for any enlightenment

if it is the same setup as
mine the ignition activates the solonoid so when the vehicle is totally off the batteries are seperated but when on they are joined for charging and discharging. There is an overide switch so if one battery is dead flat without enough power to activate the solonoide you flick the switch and the solonoide opens allowing your secondary battery to start the vehicle

Make sure it is wired up properly,sounds like it is permantly closed.
If both batteries are charged and you start the car, about 10 seconds later you hear the isolator cut out to seperate the batteries.

Which solenoid is it? The totally sealed electroninc one seperates only when the batteries drop to a predetermined volatage. If it is the manual solenoid, it joins the batteries when ever the ignition is on even if the motor is not running.

It should not be discharging both batteries. The two batteries should be seperate until you put the ignition to "on" then after about 1 minutes it should "join" the two batteries together.

Hey there Conman,
These simple solenoids are like a switch and when closed it will complete the circuit bringing both batteries together in parralell.
You have one alternator, Battery 1 (starting) and Battery 2 (aux) and to charge them both from one source (being the alternator) you can use this type of isolator. If it has no smarts (i.e it doesn't measure any voltages, rather rely on what it is told to do by what state the car is in, running or not.) then check the following:
The first thing I would check is that with the car not running and the key in the off position that the two batteries are indeed seperated via the solenoid. That is the solenoid is open circuit. Then I would check at what position the key has to be in for the solenoid to be closed. That is the solenoid creates a closed circuit. You may
well findout that you have applied a permanent/non-switched 12volts to the control side of the solenoid meaning that the two batteries are parralell all the time.
If the above is the case then look for a 12 volt switched source (i.e.ignition 12 volt)as per your installation instructions that I assume would have come with the unit. If you need more help repost after looking at these first.
Regards,
Stuart M.
