I refurbished my alternator by changing the rectifier and regulator but the warning light not clearing
wow my hats off too you , im not knowing anyone that actually opens up one of these to replace the rectifier , any hows , if you use a volt meter that has a pretty good screen , you will see if charging system is working , placing red probe of meter on + battery term and black probe on - of battery , with car off you should have right about 12 volts after you start car and idle it you should have 12.5 to 13 volts , and this will increase to as much as 14.8 volts as you rev it up a bit if your meter doesn't show these then you still have problems in your charging system
When starting my 93 Lexus GS 300 all it does is male a clicking sound but wont turn over or start
the starter contacts inside the starter are probably worn out.This is a very common fault on toyota starters.usually a couple clicks and it starts,then it gets worse,7 or 8 then it dies and just clicks.
the click is the solenoid moving back and forth.
if you remove the starter,you will see three small bolts on top of the solenoid assembly.open it up and remove the cover.Inside you will see two copper contacts,one on each side one is much bigger than the other.When the solenoid pulls in it connects the two.Remove the sets of nuts that the starter wires go to and the insulators and washers to change the contacts which can be bought from the dealer for 15 dollars or so. make sure to put the washers ,nuts etc back in exact order of removal.best of luck.i have repaired over 50 starters.the actual starter portion is not the issue.
My Lexus GS 300 won't go over. 20 mph
Its in, what you call limp mode . You need to take it to a garage.they will plug it in. There will be some fault with the car. It goes into limp mode. So no more damage . Can happen.
Starts but shuts off after a few seconds.
what year is is, for one. Does it have distributor? It could be all sorts of things. If you have to diagnose it you need a fuel pressure gauge to see if it has right fuel pressure. Next, or really first, check for spark when not running by removing one sparkplug wire and having someone crank the engine and the wire end needs to be placed near a ground to see if you have continuous spark. you might need to stick a phillips screw driver to provide a better path for electricity to jump.
