Car sat for about 4 days...cold out, but not below freezing and all.</div><div id="yui_3_16_0_ym19_1_1460162693339_13351"> Wouldn't start today. Horn and lights test said Battery Faded. Last time that happened I left the radio on for a couple days...volume off. Charged battery and all was well again.</div><div id="yui_3_16_0_ym19_1_1460162693339_13392"><br></div><div>But this time, no lights, battery or anything on. The squeeze ball batter check thing had all the battery cells right up near the top. Charged it for a few hours and, voila...car started.</div><div id="yui_3_16_0_ym19_1_1460162693339_13636"><br></div><div id="yui_3_16_0_ym19_1_1460162693339_13477">.Is there any way to test to see if there's anything in the car that's "on"...draining the battery when the car sits for some days? Some wire problems?</div><div id="yui_3_16_0_ym19_1_1460162693339_13486"><br></div><div id="yui_3_16_0_ym19_1_1460162693339_13574">Question 2: Can all battery cells test OK but the battery still not doing its job properly?</div><div id="yui_3_16_0_ym19_1_1460162693339_13590"><br></div><div id="yui_3_16_0_ym19_1_1460162693339_13611" dir="ltr">Then...found that the battery ground strap was very frayed...more than I noticed before...it being kind of hidden. Replaced that with a solid battery strap...then the car started. (I should have tried to start it AFTER re-charging, before changing the ground cable...but didn't.)</div><div id="yui_3_16_0_ym19_1_1460162693339_13650" dir="ltr"> Plus, I cleaned the terminals (which weren't corroded or anything), and played with the screws at Voltage Regulator...again, before putting the battery back in.</div><div id="yui_3_16_0_ym19_1_1460162693339_13660" dir="ltr"> So....is there anything to learn here? Or is it Yet Another problem solved by magic?<br></div></div></body></html>
