I'm wondering how many ECN members get involved with automotive electrics from time to time.

In my area of rural England, there are plenty of mechanics at local garages to carry out oil & lube jobs, brake replacement, and all the other "grease monkey" jobs, but few who will get involved with wiring.

As a result, I seem to get called upon fairly regularly to look at vehicle wiring. Many problems are very simple to solve, being down to vibration and corroded connections. Other times people have bought extra lights or fancy radios (sorry, "in-car entertainment systems" ) and don't know how to wire them in.

Tow-bar wiring is another favorite, and the associated systems in travel trailers. The latter seem to be a cause of great confusion to many people.

Sometimes the job is even simpler, like Volvo owners wanting to disable the daytime running lights.

So how about your neck of the woods -- Do you get involved with this sort of thing?

Why would you want to disable the daytime running lights??? English/American invention which significantly reduces accidents.

Because it's a waste of (very expensive) lightbulbs to have them burning during bright daylight. Kind of like keeping your front-door light on so people can see your house during the day.

It's bad enough that they're making these lights so bright that the oncoming traffic practically blinds you.

Er, Sven... majority of DRL's on cars today use the high beam filament running at a reduced voltage. The low beams used during normal regular night driving will burn out well before the high beams do.

Sven, I think you'll appreciate these links:

And from Britain:
Drivers Against Daytime Running Lights - UK

Does that answer the question as to why I get asked to disconnect DRLs?

English/American invention? I thought they originated in your part of the world.

Good day my friend, how's things on your side of the pond??

Last vehicle I worked on (4 yrs ago) was a NEW rescue rig for a local trauma center. It came from the Mfg with a host of 120 volt problems, bad shore power interconnect, 240 volt hyd. pump motors for "jaws" with a 208 volt genset, etc.

I spent about 50 hrs on it, and believe me, I couldn't get done fast enough. It was tough. Tight spaces, had to dis-assemble a lot to access the genset; be a contorsionist to get to the pumps, etc.

I normally stay away from anything like this, but, when I first started working where I am now, I had the job of assisting to wire a Mobile Lithotripter Bus with Mains and Inverter/Batt systems in it, as well as the standard 24V systems.
Never want to work on ANYTHING as complex as that again, it nearly ate my brain!.
But, having said that, I still install the odd stereo player in cars for friends and other small jobs.

I do a little (personal mostly) Auto Wiring here and there.

Audio systems, Window / Door locks, and similar "simple" stuff.

Used to really enjoy working on Autos (like back in the 1980's), but now its a different story!

I work on the side for a car dealer friend of mine, He can buy a car at a discount because the radio/heater/"Tokyo by night" dashboard doesn't work.
I get to fix it, get paid for it and he can resell the car. Everybody's happy, and I can buy my cars cheap.
That and I can work on my own vintage British car's wiring, The wiring is easier to figure out than the diagrams!
I also rewire the odd steam loco too. steam driven generator at 32 vdc.
