I'm getting my head around installing the Orion 121230 DC-DC to my camper. It's for the Citroen Relay (old style non-smart alternator) charging a bank of 2x130 Leuch Adventurers.
I've got a convertors' socket which gives me my link to make a D+ style signal to tell the Orion that 'I'm charging' (see the photos from MisterG.org.uk site) but can't work out how this helps from the manual.
Even after digesting the manual, I'm unsure as to how/if I need to link the orion to the alternator- I got stuck at the 4.4 a- L-H pin wiring b- H-pin wiring and c - L-pin wiring section of the manual.
Looking at the next section 4.5, it talks about an Engine On setup and I've found a download which outlines how to setup a smart alternator with variable alternator voltagges (which doesn't apply to the Citroen).
Please can anyone point me to the next step or where to look to help get my head around it?
