Redid the head lamp wiring on my 82 P-30 motorhome chassis, positive lead from the battery through body connector, only about a dozen Package Electric terminals on that, just put on all new connectors, Head Lamp wire went directly to the head lamps switch on the dash with all but three terminals on it and a fast acting circuit breaker, Big heavy plated terminals, that just need a minor cleaning and coated with Lubriplate. 12 volt out for the parking on the first click, on both terminals when pulled all the way out.
Head lamp wire went to the dimmer switch, just got a new Standard for a couple of bucks, simple form C switch, 12V to either the dims or the brights. Still had plenty of automotive grade pretinned wire left, when you could buy a thousand foot roll of this stuff for ten bucks, a dime a foot.
Uses that four rectangular head lamp system, can buy both dims and brights, but the brights are stupid, just two terminals, if you connect that connector to the dims, only the brights would work, bottom terminal is for the dims. But having four dim and brights, if the dims on the outers go out, just switch that lamp with the same one in the brights. Dims burn out the quickest because always used.
Very simple system, should have left it this way and extremely reliable. Going though the BCM using cheap made in China relays and fast acting fuses is totally stupid in my opinion, and experience. Even dumber yet is storing that extremely valuable code in electrically erasable memory. One 0.75V glitch would reset it back to zero and a microcontroller is next to worthless without code.
If you don't have enough brains to switch on your head lamps when conditions call for it, shouldn't even be allowed on the road. When that blazing sun is on full blast, can't even tell if the DRL's are on and just wasting energy.
But like ABS, some dingbat professor in Stanford was given a grant to say its 14% than non-ABS, so even more idiots in Washington DC make it a law. Haven't done this with DRL's light, but a so-called safety feature, but sure not safe if you don't have any head lamps at all.
What should be a law is making fog lamps a requirement, would only add about eight bucks to the cost of the vehicle, and at least you would have an independent system of some light if your head lamps should fail.
Not easy living in a country ran by idiots. DRL's are a nightmare for most people that don't have over eight years of electronic training. Plus the experience to boot.
Point contact relays are really stupid, one tiny dot of arcing can prevent them from making contact. A shorted transistor or a stuck valve in ABS, you would have no brakes at all, how stupid can people be? What happened to KISS?
