First off I appologise for a very minimal Vanagon content, but it does relate to a VW and it is part of my collection which includes two Vanagons... As many of you may already know I am the proud owner of a 1980 Volkswagen Iltis. For those who don't know, it is a military "jeep" that Volkswagen produced for the German Army from 1978 thru 1981 and was later produced in Canada from 1984 to 1985. Seeing how it is a military vehicle the electrical system is 24V DC as opposed to the 12V DC we are used to with our Vanagons. I want to be able to connect a CB / HF Transcever, VHF Transcever as well as a CD-Player in the dash. All of the radios that I have are 12V and will more than likely not appreciate the additional voltage. Some people suggested to me to take 12V off of one of the two 12V batteries. It has also been pointed out to me that this with setup cause uneven charging of the batteries and will constantly kill one battery. One item that was suggested to me was a 24V to 12V voltage regulator that can be bought at some truck stores for about $150. This is what I was thinking... it seems too simple so there must be a problem with it. Take two 12V lights and wire them in series (12+12=24). Use these at daytime running lights or something simular. Attach a 12V device in parallel to one of the lights as the difference across one of the lights would be 12V. I guess the flaw in my logic might be that if they were two IDENTICAL 12V lights then they would take 12V each... if one light, or one light and the 12V accessory attached to it take more current than the other, the voltage will be different... am I right or am I wrong?
