Can anyone explain to me how this works, I heard it humming the other day and thought it was a vibration,so turned it off. I forgot to turn it on and the engine wouldn’t start, re connected,turned it back on and it started fine and has since.
I’m wondering how and why it works, as I wouldn’t have thought the engine battery would drain when I’m on site as I assumed it would only effect the leisure battery, but also it was on ehu so why would it drain anyway.
What battery does it charge and I hear it humming a lot more recently, so I’m wondering have I got potential battery issues.
I haven’t tried battery only hook up as yet.
Thanks. Mark

If you want to know what battery it charges try putting a voltmeter on the battery and switching the charger off/on then you should see the voltage change.

When you say it started fine after turning it back on, do you mean after a period of time?

Might be that your starting battery is duff.

I think you've hit the nail on the head Martin but, yes the OP needs to give us the whole story, not just a potted history.

That’s what I’m wondering. Do I need a new battery.im now in spain(where is best if needed)?
Yes it worked after I had re connected and turned it back on, but only for a few minutes.
Why would being connected and parked have any effect on the engine battery, why an effect on any battery if I’m mains connected??

I think first thing you need is a voltmeter to check the volts in your batteries, It is possible that your starter battery will only hold a small charge while the charger is on connected, possibly there is something connected and using the battery power or possibly the battery is just plain old k-------d.

If you are connected to the mains the 12v things still run off your batteries except that the batteries could be shot and you won't know as the power will come from the charger.
