lexus for life Posted October 19, 2011 Share Posted October 19, 2011 I have a 98 LS400 when I put on the lights and come to a stop my radio goes off and the lights on the dash start to dim. When I start moving the radio comes on and everything is ok. I took it to the dealer and paid $89.00 for a diagnostic and they told me it could be the alternator, battery or termnals. This was just general and they too did not seem to know what was wrong. I changed the positive terminal since mine was not in good shape and it is still happening.

SW03ES Posted October 19, 2011 Share Posted October 19, 2011 My guess is the alternator. I'd replace the battery at the same time since often a failing alternator will take the battery with it... Quote Link to comment Share on other sites More sharing options...
