Hi! Im a bit new to the PDM world so bare with me here if this is a dumb question :)
I have a 2002 Lotus Elise S2 with a PDM15.
I'm trying to trigger the headlight switched on, headlight flash, left turn and right turn signal that comes from this type of indicator stalk.
Coming out of the stalk relay are 4 wires. Fair enough I thought, one for each input then
Problem is that it´s only the headlight flash that accually switches to active high as I hope.
So that one I can trigger the headlight flash for
The others though, they give very little change in voltage. Inputs for from like 2.54v to 2.55v or something like that ...
So how should I setup or wire this kind of relay?
I think it´s a 30,56,56a,56b relay if not mistaken ...
Is it so that the relay only has one output (headlight flash in this case) that can be used as input? The others are just switches...? Any help would be great, or tips on where I can read up on how these work
hi paul,
so the wiring I´ve got that now works with the PDM input/output is this 12v goes to pin 49a 12v goes to pin 30 12v goes to pin 56 With this setup, when I flip the indicator down/up it gives out 12v on 49aL (left) and 49aR(right). For the main beam, the output 12v is from pin 56a. This pin is outputting 12v on both moving the indicator in and out (flash vs constant) Hope this helps. I´m not saying it´s the best way to wire this indicator, but it is one way ;) The hazard light indication is then separated from this, coming from a keypad in my case.
