Re: Hello from California - 2005 Cherokee kills batteries
Hi- As a matter of fact my home brew low voltage alarm just triggered in the house 15 minutes ago to advise me the batt voltage is below 11.79 volt dc. I got tired of jumpering if jeep sits for 2 days. so I built an alarm. Engine is currently running as I write HI! I've got all the electronics to fix anything, but my arthertis in my shoulders kills me trying to get under the dash etc. Here is a brief listing of other peoples ideas and my own. Fresh new battery, checked ALL 6 diodes for leakage, looked under seats for rubbing wire looms possibly shorting when seats are moved. (Don't have seat warmers so didn't do that.) Measured current from battery. About .050 Ma once door closed and inside lights dim off. About 1.5 amps with door open and inside lights on. checked starter wiring loom. checked around inside fuse block USA steering on left side. I am trying to catch the current when jeep is trying to kill battery. If I pull the JB fuse the battery voltage remains constant. With the JB fuse out and I start the jeep the headlights come on until I insert the fuse or shut the engine off. This is a consistant INTERMITTANT -- In otherwords, if jeep sits for two days =dead battery (4.5 volts) If wife goes shopping every day car is good to go next day. I suspect current drain is 2-4 amps in order to deplete batt that low over 24 hrs. BUT not a hard short! Recall a dead short will either burn up the wiring or blow a fuse somewhere. Thats where its at at this moment. I have years of communications radio installs and repair plus engineering and honestly this problem would be easier if a fuse would blow. Oh well... you asked..
