I've started installing a Projecta IDC25 DC-DC charger and can't decide if I should connect the blue ignition wire or leave it open?
On a previous thread (viewtopic.php?f=121&t=26010&start=200) rjo89 said "I left the ignition wire open and it appears to be working fine, charging and isolating as it should. Any questions feel free to ask!"
Why would you leave the blue ignition wire open if the manufacturer recommends it be connected?
Cheers and thanks,
