Mycroft

Thanks for the help to those who posted on this thread. I got my headlights working good enough for now. My headlight fuse gets warm on low beams and takes a while for the fuse to blow with the high beams. Good enough for around town. The problem now is that the warm fuse speeds up corrosion of the contacts and they need to be sanded down every so often. Anyways, I found a Datsun 510 and PL521 Pick-up Owners Workshop Manual 1968 thru 1973 (ISBN 0 85696 123 X). It has a very different electrical diagram than the one floating around here on the forum. Here is a link to a site to buy the book --> http://www.isbns.net/isbn/9780856961236. It's quite cheep. I found mine in the bathroom on the book self at the scrap yard. I payed $10.00 . Good luck with your truck!

Can someone please help me with my electrical problem. I keep blowing a fuse running my head lights. I disconected everything else but the headlights. I'm running a wire stright off the battery to the fuse box, like in the diagram. The fuse that keeps blowing is the 10 A fuse connecting the black wire from the battery(+) to the red-black wire that runs to the light switch? I checked for shorts but I didn't find anything. I replaced the old red-black wire and the fuse lasts longer but it still gets hot and blows. I'm at a loss here, someone throw me a bone! diagram --> http://community.ratsun.net/topic/50160-datsun-520521-pickup-wiring-snag/
