testing rebuilt gauges

[fireguyfire]

Hey guys;
I have refaced my old gauges as recommended by lilwendals excellent thread on redoing your entire gauge cluster; I am ready to test them, and he recommends using a lantern battery run through the voltage limiter to get the 5 volts needed; can anyone clarify for me how to do this? Do you put the voltage limiter on the positive lead, and run the negative to the gauge?
Also, when making up different ohm leads for testing he says to run 2 150 ohm restistors in parallel to get 75 ohms to the gauge; again can anyone clarify how I would make a testing lead with the 2 restitors soldered in in parallel?
Any clarification would be a great help!!

See my thread for additional help. http://www.dodgecharger.com/forum/index.php/topic,67620.0.html  I used a resistor box to get the values I wanted. http://www.amazon.com/gp/product/B0002KX76M/ref=pd_lpo_k2_dp_sr_1?pf_rd_p=486539851&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B0002BBQLY&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1J43BBXKEGGCMAJ6TXDX

I sketched up a quick schematic of the circuit you want to create. The ground on the power supply (battery in your case) and the other end of the resistor (75 ohms in this senario) connect to each other as shown. And it does not matter to which terminal on the gauge you connect the resistor (or power). I hope it helps, and don't hesitate to ask questions.    It can be confusing.
