I have a 1992 SC 300 and on friday i was coming home from work and i noticed my panel lights went dim then i noticed the ABS light came on, and my radio started cutting in & out, I was almost home so kept driving and noticed my panel lights were getting even darker i went to turn my blinker on and my gauges went crazy and all dropped. My car then started to lose power and when I went to turn the power steering seemed not be working too well...I made it to my house parked my car and it started losing even more power and struggling to stay on then it died. I noticed when i started my car that day and the day before it was idling real hard but seemed to calm down after waiting for a bit for it to warm/cool. After the car died I tried to restart it and it wouldnt. A few hours later I started it it seemed like normal so i started it was going to take up the street to see if it was ok I turned the radio on just to check it, the radio turned itsself off then the headlights went off, and it started riding rough and it died. Anyone have any ideas what could be the problem. I replaced the alternator about 5 months ago so hoping thats not it. Any help is appreciated. This one has me stumped.

anyone have any thoughts of what could be the problem..somewhere to start?

sounds like a combination of possible issues..

-alternator possibly drying that old battery
- the main fuse
-But most importanly that radio is doing something.... so try to drive the car with the radio off, that way you can find out is something is wrong on your radio harness,affecting the daily driving .

Thanks I actually replaced the alternator about 5 months ago...and because the battery was acting up i replaced like about 2 weeks ago. It does the same thing even if the radio is off. Could it be something with the ABS since thats the only light that is on..except the engine light that has been on since ive gotten the car. Thanks for your help.

There is a body ground next to the battery that can cause this issue, you also should probably replace the negative battery cable between the battery and the starter.

All signs of low voltage, check your charging system first....then go from there

Thanks everyone for the suggestions...it gives me somewhere to start...I appreciate your input.

I had this problem on a car I had years ago and it ended up being the voltage regulator,I'm not sure if the sc has a voltage regulator...I would think so... and if so I would start there...just my 2 cents worth...good luck

Thanks its worth a try..I swapped out my battery terminals just in case it wasnt getting enough contact i had to jump my car and this time it stayed on for a bit longer but then again the panel lights went dim and it struggled to stay on.

Get a voltmeter, your wasting your time if you don't do the basic diagnostic tests first

I had a similar issue, turned out it was the power wire going to the fuse/relay box in the engine bay.

Thanks Chris I keep feeling like it is something like that...I have a question if anyone thinks maybe its related to this...when i replaced my battery a few weeks back the guy put the cables on the wrong sides and blew my alternator fuse then proceeded to pull it out with pliers and touching the connectors together so i could start my car which made my Airbag light come on i got that code to clear...and all this has happened anyone think maybe that could of caused this problem? Thanks for all the help.

if the problem continues....maybe ur car just doesnt like u. might sound weird....but it happens man

Hi all update...so apparently it was my battery that caused my car to wig out. I took my battery to be tested and it was low 8.4v so autozone charged it for me for free i hooked it back up car started and is doing good no more ABS light, no shaking..doing good so far! Thanks for all the help
