another find on ebay. never seen anything like this before, sorry if its a repost or anything http://cgi.ebay.com/ebaymotors/Datsun-Pick-up-620-1978-Datsun-Pick-up-6x6-/251018546367?pt=US_Cars_Trucks&hash=item3a71df0cbf#ht_500wt_1182

right now with the lights off it stays steady at 12.10 volts, with the lights on it drops till it dies

Hey everyone. Getting ready to move to baton rouge next week and trying to get my 620 up to the task. it runs fine as long as you dont have the lights on, then the voltage drops dramatically at the battery. i changed the voltage regulator but that hasnt fixed the problem. there's an aftermarket radio the PO installed but its not hooked up (he had it wired to the power wire for the hazard lights, wtf?) and he hooked up trailer wires to the back of the truck so im gonna check if they are short circuiting or anything. going to take the alternator to auto zone to have them test it. anyone else have any ideas? i did some research on here but 'really find anything. i appreciate the constant help guys! Russ

hey appreciate the info

So the relay i ordered off of rockauto and had hooked up decided to burn up. the corner is fried and i have to tap it to get it to click out of high beam. just ordered a new one from autozone that has a lifetime warranty. ugh this truck is really making me mad sometimes

hey everyone. saw this on ebay and wanted to make sure i was correct. dude says its a 72 but i find that hard to believe cause the data plate says it has an L20B and its a long bed...cant be a 72, right? http://cgi.ebay.com/ebaymotors/Datsun-1972-Datsun-620-/180828268374?pt=US_Cars_Trucks&hash=item2a1a346756#ht_500wt_1182

nah theres no green wire, its a red/yellow wire that goes to the hazard light harness which goes to the switch

hey daniel i used your information and got everything working great. had to make a jumper wire from coil to com. thanks!!

thanks for the info daniel. my 620 has 4 wires, red supplying power, red/white, red/black and red/yellow. the red/black i believe goes to the high beams, red/white goes to all four lights, and red/yellow goes to the hazard control switch which links into the high beam/low beam switch.

im in louisiana. i figured out one was the horn relay and got a new one. took the old headlight relay apart and nothing is burnt or anything, but its still not working. we could get the old one, and the new one, to work with the high beams and low beams on all the time, but not the low beams by themselves and be able to trigger the high beams. checked the switch in the cab and it it worked fine.

hey everyone. finally got the brakes good on the truck so im trying to tackle this headlight issue so i can start driving it. called nissan with the original part number, no relays are available anywhere in the country. would anyone happen to have an extra one somewhere? had three different people look at the new relay and try to get it to work; no one could. thanks!

Hey everyone, I need a headlight relay for a 74 620 pickup. nissan doesnt make them anymore and mine took a shit. shipped to 71446. thanks!

datsunaholic, you were dead on. used a 10mm line wrench, rounded them off, then used the vise grips to get it off. PITA. im gonna order the new wheel cylinders from rock auto; the ones i got from autozone never came with that piece. thanks a bunch!

hey guys, does anyone know where i can get this part? the nissan dealer says they are no longer available and both of mine are unusable. this should be the last thing i need to get it going. thanks!

hey thanks man, appreciate all the help.
