dimming lights
Hey CL I have a 92 es300 and I started it last night and the headlights, dash, etc would dim as I put pressure on the brakes. I read some threads on here mentioning the alternator so I decided to check it... I checked the battery prior to starting it and it was reading approx 12v so that’s fine, but when I started it I checked the alternator and it was at about 13v decreasing so this is what’s leading me to believe it the alternator. I saw that in a 96 es300 Toyota went cheap and installed an alternator that wasn’t powerful enough. So does anyone have any suggestions or if it’s possible any knowledge on a compatible replacement. PLEASE HELP!!!!!!

if you use a meter, it should show the battery voltage at around 14V or a bit more, while running/charging. if you are getting 13V and it drops, maybe it is alternator. Our local pickapart sells u-pull alternator for $30. make sure the electrical connection plug is the same as your 92, as i noticed there are round ones, and also shquare/rectangle plugs, and they are different. I have to take my brush assembly off my old one to make it work with my new one.

thanks phil. i went out this morning and i checked it before i went and the alternator was reading perfectly fine and i took the battery in and had it tested and it was fine, so i just got new connections and cleaned up the terminal and it seems to be dimming less now so i think it may have been something with the connection. im still unsure at the moment.
