Hey Guys, this is my first time posting to this site but have used it sucessfully many times for the last 6 years with great success! I need some help in figuring out why before I replaced my 12 volt battery, my gas guage working fine with a full tank of gas showing on the guage, but after installing the new battery and making all the connections , the gas guage flashes one bar. I checked the 3 connecting plugs on the positive post and re-check with the same results. I tried unplugging the positive cable connector for several minutes with the same results. I've checked all the forums and can't find anything like this problem. Any help would be appreciated. Also does anyone know what the single wire plug is and the multi- wire plug going to compenent next to the 12 volt battery is? Thanks in advance!!
If you bought an Optima battery, that's likely the problem... Return it! They're junk batteries... But if your new 12v is fine and there's nothing wrong with the wiring/connections, the always problematic gas gauge calibration will likely resolve itself after a cycle or two of filling up.
welcome! not sure if this is it, but try searching 'gas gauge reset' for directions. but maybe it's just the leftover unconnected wires?
Relax, anytime the 12v power is interrupted, the gas gauge defaults to one blinking dot. My 2007 typically starts indicating correctly within 10 minutes. The 2005 I recently bought took a day. You also lost your radio settings and the auto up/down feature of your power windows. Reset the windows by holding the switch in up position until the window is fully raised + about 10 seconds. Not sure what you're describing being next to the battery, but the only item next to the battery that I remember is the capacitor bank (black box) used as emergency power for the brakes. It only has one connector and I think it has like 9 or 10 wires. The only one wire connector in that area that I remember is the one that plugs into the (+) battery terminal block assembly. I think that's the voltage sensing wire used by the inverter. (may be wrong on that)
Thank to all you guys for your responses! You was right TMR-JWAP: before I got out of the driveway the gas gauge corrected itself. This site has always has been a great help to me and I truly like to thank everyone that participates!
