Hi everyone so I have a 1994 sc400 237k miles. I was having alternator issues a while back so I replaced my alternator and it ran fine after that no issues at all. Recently all my interior lights and head lights tails all of it are flashing now whenever the car is running. When it’s off the won’t flash everything is normal. Also it idles kinda rough and if you just let off the brake while it’s in drive without pressing the gas it will start to jerk a little bit instead of smoothly taking off. Haven’t had my battery light come on at all and no problems with it charging. Unplugged the positive terminal while the car was running and it ran fine. Any ideas?

When you replaced your alternator, did you check your power steering pump to made sure it wasn't leaking? If it's leaking and you have a new alternator, odds are it's causing interference with it, and may damage it. When it's off it's running off the battery therefore most electronics will be stable, unless the battery is dying then you will see things randomly act weird, or die all together. Hope this helps some
