White wire (Signal)

[tiggs]

I have a 2007 Vanmaster on a Fiat Ducato 3ltr I am in the midst of having a lithium battery, Victron ip22 30amp 3 charger, Victron dc to dc , and a 2000 inverter . My question is on my original charger a CBE PC - 200 had a white wire called a signal wire that is connected to the control panel can I still use this and if so how and where do I connect it thank you

Check if you get +12v on that wire with the engine running. 0v when not running.

As far as I know, that wire is to enable the indicator on the control panel that tells you the hookup is connected. I don't think it does anything else. I think it's used because if you just use the charger output to switch on the indicator, then the indicator goes out if the charger is switched off, even though the hookup is still connected.

I don't think there's a simple way to get that function back. You'd need a small 12V power supply or some other permanent 12V output to replicate that function. The good news is that I don't think it does anything else, other than indicate the hookup is connected.

That's exactly what it does on mine, didn't bother to replace it with anything, mainly because when I plug in Julie tells me if the kettles working, did think we could use one of the relays on our multiplus which would have been better than the original "Charger On" indicator.....

Thank you it does say in the manual that it diverts a 2 amp charge to the cab battery if the leisure battery is full when on hook up but as I am not going to be on shore power very often that does not bother me. Thank you both for your help another thing ticked off

Yes it will still do that without the white wire, when the leisure battery is above 13.5 volts and the main panel is switched on a relay will parallel the Cab and Hab batteries.

I used one of these connected to the original power supply 230v (replaced with IP22) which is only on when on EHU. I believe it stops the battery low warning etc operating as the system then knows it's on EHU, which is why I reconnected it.

Other than niggles, I don't believe it does much else.
