DIY Headlight relay Kit, and other bits - This may offend

[Switch]

So, my relatively newly acquired 72 US/UK '6 has come back from having it's clutch work done after the pin through the fork and rod decided it wanted to be in 2 bits.

The next things to start on are mostly electrical.

Firstly Gauge bulbs. A set of ClassicCarLed's applied and things are visible again! The rheostat is still in place until I get round to the next project that involves the hole for it and a few other bits.


Secondly is the headlights, the passenger side wasn't ... reliable. A bit of jiggling sometimes required with the wires in the front passenger corner needed to make it work.

So. rather than dig into the loom and whatever is going on up there. I devised my own relay kit (1 relay per function (Side/Dip/Main)), with an incomer fuse into each relay, and an output fuse per side and function.

Picking up the Side/Dip/Main beam 'signal' by running 3 additional wires (plus the 3+ground for each H4 connector/each side) into the passenger side bowl and then spade connectors into the H4 fitting, meaning that all the "original"(to me) wiring is still in place and untouched. Just with a second set of H4 sockets in each bowl, fed from the relays.



Picked up a new 12v feed and a ground from near the fuse box. I'm not 100 happy with this just yet. Some re-routing and probably putting it through a 30A fuse in the box for ease.



Fitment and wiring aren't final yet, I'll probably cover the lot in a black wrap and hide it a bit more, but it's good enough for testing.

I'll be fabricating a custom 3d printed support/bracket for the Relay/Fuse holders on the bar shortly.



While I was fiddling around I tried out some 7" units I had to hand...




They're probably getting changed, but...

Haha, well would you look at that.

I've just said on the US Facebook TR6 group that your headlights make the baby Jesus cry.

No offence meant.

They do though.

What a stunning car...and just no!

None has been taken. To each their own I say.

Importantly, it's my car, not yours And thus my offensive aesthetic to cultivate. (Potentially anyway).

Not quite sure what you're driving at here?


If I was REALLY trying to cement it's terribleness I'd put a matching white strip ringing the grill inside the chrome so it had a full width "halo" around the inside of the chrome on the front end.... now that would be terrible. But sometimes I like terrible..

Showing you that there are adapters ready made to pick-up the dip and main supplies off the original headlight bulb plugs for the relay switching

Was being kind, trying to help

Ah ha! Thank you very much, my sockets just came with pigtails... So I made do with what I had and I'm quite happy with the results.

Forgot to mention what a beauty she is

Once had the pleasure of being driven to Oulton Park in a TR3A

Rewired a TR3

Love TR's

Oh yes.
Very useful!

[Penelope Stopit]

Very good then

Visited the electronics forum here yesterday and read your post about a 100 AMP latching relay, did post some info

Anyway, this relay is of a mechanical change-over type and will switch power to a heavy duty continuous current solenoid

Hi,, I built your car in the late 1990 in Plymouth, converted it from LHD/RHD took me about 1 year , it was originally imported from Texas and had no rust except the fllors and some bullet holes in the door !, I think i have a few pics of the build,
