- I was sent a hazard warning light switch for the aux panel when the Ford wiring is designed to use the switch on top of the steering column. I didn't realise until I had already fitted the switch to the aux panel.
- I was inspired by Richard Lincoln and want the Savage switches to illuminate with the side lights.
Once I had the plug wiring set up for the hazard lights switch, I set about modifying it to include wiring for the LEDs. Here's the schematic I ended up with:
It is simple in principle: there is a 5K6 resistor from aux plug pin 1 (side lights) to the +ve terminal on the LED along with gratuitous use of diodes to stop the current flowing back where it shouldn't go. The diodes are orientated so that current can only flow INTO the LED +ve terminal. The net result is that the LEDs illuminate dimly with side lights on. Then:
- The horn switch LED remains dim regardless of what's happening.
- The fog light switch is dim with the fog light off or bright with it on - the fog light feed comes from the dipped headlight signal, so only works when the headlights are switched on.
- The hazard light switch now flashes bright / off with the side lights off or bright / dim with the side lights on.
Overall, it looks great and now I'm happy.
I am trying to set up same but am clueless on electronics, what specification of diode is required please?
ReplyDeleteHi Martin, I've only just read your reply because I didn't receive any notification that you had commented. Sorry! Did you managge to find the correct diodes?
DeleteHi Ben, yes I did, went to local Maplin store. All working fine as per your setup. Although it does look like a bowl of spaghetti back there as I added the Smith clock and a spare savage switch in case I go for engine map switching in the future. Given my colour blindness, general hopelessness on electrical, I'm well pleased with result, thanks to your schematic.
ReplyDeleteCar been on road since March, done 3 track days, with Caldwell Park the next one in weeks time. Just loving it.
Do I recall you having issue with rear diff, did you get it sorted?
Hi Martin, I've sent you a message on Facebook. You may need to check your junk folder because we aren't 'friends'! Regards, Ben
