83 gauges ,83 tank, connected to 82 wiring ?

[smknjoe1964]

Finally getting around to wiring these in . Theres a black and a green wire from the tank .I cut the connector from the gauges and reconnected the brown ,yellow/black and gray wires . I have the green wire from the gauges still to connect . Does the green wire from the tank got to the green  wire from the gauges ? Where does the Black wire from the tank go ?

Glad you're asking this now.  At least when you get an answer, I'll find out, too!   ;D  I'm doing the same project this fall or winter.

Ground the black wire at the tank, the two green wires go together.  make sure you use a connector at the tank connection or it'll be really hard to pull the tank, lol  i tuck my connector in next to the coolant bottle so that i can just pull the side cover to unplug it.

extent gave me advice on installing a resistor between the black & green wire on the harness side of the tank connector, this makes the guage more accurate.  i don't remember what the value of the resistor i used was, but next time i'm outside (just came in, need to cool down) i'll get the color banding for you.

oh, and Joe,  re-disconnect that black/yellow wire, that's the flakey rev limiter wire.  be sure to insulate the cut end.

Thanks Lucky !  ;D Got'er Done !  :P Let me know about the resister when you get a chance . ;D

I used a 120 ohm resistor from the green wire to ground. The sender is at zero ohms with a full tank and goes to about 30 ohms at empty. Since the design of the tank puts the bulk of the fuel in the lower half of the tank, a linear resistor can not give an accurate indication of the amount of fuel. It only indicates the vertical level. The resistor in parallel makes the sender non-linear.
I can explain it further but you have probably lost interest by now.

I follow what your saying Walt  ! I take a 120 ohm resister and connect it to the green wire and then ground it to the black wire ? or just ground  it anywhere ?

Sorry it took so long to get back but I've been kind of busy. I put mine across the connector, green to black. The 1/2 watt resistor makes a tidy fit there and doesn't interfere with anything but green to any ground will work.
