Old battery-- sometimes doesn't start---. Charge it up last serveral months---. Only drive about once a month across town.--- When NO start I get nothing when turning on the key---. No sound at all---.. Charge it up--- ready to go--- came out turned on key--nothing.--- Charged it up had light, horn A.C. turned key on had nothing.--- Security alarm light kept blinking--disconted wire, kept blinking--= disconted both battery terminals kept blinking---. Charged it up afternoon and all night---. Next morning security light was off, but no lights or horn or A.C.--- Checked starter w/jumper wire turned over,--- replaced starter solenoid switch --- NO lights etc. Put wifes explorer battery in nothing--- checked fuses-cable and power box.--- All good. Put cheap ford scan tool on to check relay and solenoid--- test light was susposeds to read codes but SOT just stayed on without blinking--- KOEO---. Any suggestions and how much it will cost. By the way took battery to O'Reilys checked out good. Thanks
