Hi all.
This is a question for the RHD 1750 GTV (10545 S2) owners who've had to convert the original H1 Outer Lights to the H4 ones.
My problem may be peculiar to the NZ market (and I've this question in the NZ forum) but any and all help appreciated.
Background:
I've purchased replacement headlights from the UK but the outer lamps only use the H4 bulb (Hi & Low filaments) rather than the original H1 bulb (single filament). I've been cleaning up the wiring and testing the leads from the column light switch and it appears the outers get power (are on) in both dipped and full (Hi/low) beam modes. I assume this is so all 4 headlights operate in full beam mode.
Can anyone please confirm that this is correct (or describe their cars operation) so I can get my wiring correct.
The electrical diagrams I have don't cover this setup
My plan is to run the full beam lights through relays (as there are now 4 - the 2 H1 inners & 2 H4 Hi outers) which is reasonably simple to setup, but the problem I'm facing is that when using full beam, the outer lamps will have both filaments operating at the same time (with the hi/low feed from the column switch). This will produce over 115 Watts per lamp which is too much for the lamps to handle for any length of time.
So My question is; Other than retaining the original operation (by not connecting the H4 Hi beam filament), How do I isolate the Hi/low feed from the column switch to turn the dip beam off when running the Hi beams?
My thoughts would be to have a 'normally on' relay connected to the supply of the Low/outer circuit with the inner/hi beam circuit feeding the relay switch. This (in theory) would cut the power to the outer circuit when the inner circuit is activated.
Confused? Maybe I need to draw a diagram ?
Thanks to all
