electrical fuel gauge
 

i am building an electric car in the spring and am getting all the pieces together that i can think of from all you guys that i kinda know (of).
i received my fuel gauge in the mail today no paperwork. sigh. it has + and_ on the back and 2 joints soldered on the back also labeled c and r . you cant add any wires to c or r without solder so im guessing you dont hook that to anything but do you just hook it to the 144 pack without a shunt.. or do you need the shunt or something.. im not smoking it to find out. also i thought i knew how to get around on hear NOPE! lols on me i cant figure so pardon me. who am i well ive talked to paul tryed to talk to ben (thats never going to happen) and jake is building me a controller.

Welcome to the site redfox. Where did you buy your fuel gauge from, and what make/model is it?

its a alcon i know that much but there was a problem when i tryed to order it it was was listed as 85$ but when you hit "buy now" it said 285.00$ well i looked all over and its from qingdao shandong china. through some guy on ebay.. $40.00. i think thats why no paperwork came with it it says model # hto624-144v. it looks like the ones you see on the electric forklifts. or scooters in walmart. but round.

Alright, what you have is basically a voltmeter. You'll just hook that up to the + and - to your pack and you'll be set. You'll want it on switched power of course so it doesn't stay on all the time.
