[Roadsters] Fuel gauge sender rebuild

[Pat Horne]

The wire is usually bare. I looked on line & found http://jacobs-online.biz. The wire is the same as what you need. Other than the ohms/foot you can use the wire size to figure out which nichrome wire you need. You can contact them to be sure. 

An easy way to space the wire turns equally is to wind another wire of the appropriate size to space out the nichrome wire, then remove the extra wire. 

Let us know how it turns out. 

Peace,
Pat

Thanks for the tip.  Yes, it is a unique part for that year 1964. Does the resistor wire that Nissan used have some sort of coating.  I ask because I saw a write-up for a VW bus where they were re-winding their sender.  It said that the windings can't touch. Their example had much bigger wire, used epoxy to hold the windings in place and had a few millimeters of spacing between windings.

Charlie,
 
The wire is not copper, but a resistance wire. I think it is only connected on one end. I suppose the wiper is grounded. I am not familiar w/1500s so it may be different. You should be able to measure the resistance of a length of the wire, convert it to ohms/foot & find some replacement. Is the sender different from the 1600 sender?
 
Peace,
Pat

Has anyone ever rebuilt the copper winding on a 1964 1500 fuel gauge?  The wire from the winding broke off my tank sender.  I ended up soldering it back onto the windings and believe that it used to be a solid strand of copper from end to end.  Since the winding is the connection between the ground and the gauge, I do not believe that the long end of the winding grounds to the housing.  The 1500 is a positive ground and grounding the wire from the gauge pegs it full.  Unlike later years, there is no resistor between the sender and the gauge on a 1500.  A dab of solder now goes across sever of the windings.  The most that the gauge will  show now is 1/2 full.  At least it's not showing 1/2 empty!  ;-)
 
Any ideas on how to go about this and what wire to use would be appreciated.
