Datsun 620 Resources Wiring and Manuals

Recommended Posts

Since the old site hosting service manuals, wiring diagrams etc is gone and I figured I'm one of the few with most of the docs, I decided to start a new one. Will be adding more info over time. Always open to guest contribution too if you have something to add.

The site is datsuntrucks.com or see below for direct links to documents/pdfs.

I need to know what gauge wire is on the side marker lights & tail lights 
on a 620.......I have looked & looked on this site for an answer but have
not found the size wire I need to rewire my 620 tail, marker & blinker lights .
I just need a bit of help. I have 4 rear 620 light buckets to restore
Thank'y Yalls.

Probably 16 or 18ga. Run 14 to be safe.

 

Bulbs are 23watt and there are two. I upped to 25 watts and 14 volts when engine running so 1.785 amps X 2 = 3.57 amps 

 

14 gauge 7-24 strands copper wire will handle 10 amps (20 gauge will handle 3.5 amps) so you're good.

The only upgrade I will be doing is maybe a 50-70 amp alternator.
keeping her as OEM as possible

 

I put a 100 amp Altima alternator in my 710. The power wire from the alternator was thicker than the original battery cables!!!!! Just saying to run a thicker wire. I soldered a large lug on the end and bolted it to the positive cable at the starter. The front one is the battery cable.

I am not planning on running a big audio amp.
I am deaf enough at 59.
There is also a need to keep the wire the same for resistance purposes.
I just want more than a 35 amp ALT.
If I was out west, I would just put a solar panel on top.

Liiiiiiiiike GA is a shady s-hole.  
 

I really enjoyed my time there. 
 

Resistance is great, but gauging up the wires reduces heat. Best to let the load draw what it needs efficiently.
