Trailer detection - switch for LED
Hey guys,
Lots of jobs on at the moment. Getting fanger ready for family service.
Today I tidied up the **** home made Anderson plug bracket and made a switch for LED trailers so the car knows the trailer is there. All started because my boat trailer needs reverse signal or the brakes will lock on.
Off to Bunnings, bit of alloy flat bar (best decision ever, did 3 jobs with it today) came home and made the plate to hold the Anderson plug in the nice black cover. I mean it's a rrs.. Need to be pretty.
Then found out I already had a reverse circuit. Thanks lr. Painted everything in tectyl then reassemble. Only to remember I have LED on the boat trailer(which I need to pickup and rego tomorrow, pulled apart. Spliced and heatshrink the blinker circuits and ran to the aux battery compartment.
Ran each blinker to the common of a dpdt switch. Ran the output to a led load resistor then to earth. So when I flick the switch. Bam I have a trailer. Same as the old D4. But in the D4 the resistors were kinda ziptied up to hang in the air. This time I used more flat bar and built a mount for them and even used geek glue ( the stuff the Jay car guy told me to use, heatsink paste?) To Mount them out the way and help dissipate heat.
Anyway.. another day done. Now the car recognises trailers with led lights. So that's a win. And I can reverse the boat. And power the fridge in the van. And the back looks pretty.
I also did a service, filter cut, trans service, all is going well enough to book into Cambo for a box tune. So that's cool too
Oh wasnt happy with the switch I bought. So I'm getting the one in the photo to blend with the rear interior
