How long has the light been on? Although the battery is ok, it most likely means it is not charging. Take the suburban to a parts store for a free check of the system. They should be able to determine if the alternator not charging.

Lexus ls 400 1996 flat batteriy ok now but security light on found away to start the car but every time i turn the key off securty light comes back on


FLAT batterY?? Battery OK,now? New one? Old one OK?HUH?
Get security codes FIRST: radio and NAV.
Disconnect battery from car and wait for 30 seconds and turn on the headlight switch,DURING the battery disconnect.
Turn off the headlights and reconnect the battery.
the security system should "re-boot" and be happy.
then there is the radio issue, Get the code.....

Battery Light came on... battery terminal( neg) has acid buildup... cleaned and replaced with new battery... battery light ok at first... one day later... battery light is back on?


is the alternator charging properly ! at battery car off with no accessories on, should be at least 12.6 volts. with car running, at the battery there should be at least 14.2-14.7 volts if alternator is good. but make sure belt for alt. is ok first. if lower then 14 volts change alternator. good-day !

No electrical power to anything - even dome light.


Check battery and chassis earth connections are ok.
Check for 12v power at the fuse/power disrtribution fuse bus; - if no power there, trace circuit wiring back to battery.
