When headlights are turned on there is an obvious loss of juice, engine labors and clock goes dim

There is a light sensor that is responsible for turning on the lights in dim condition. Obviously, it is not working and needs to be replaced to restore normal operation.

bad connection or bad earth check all connection or bulb

Check voltage at battery while starting. If good, check with headlights on. If headlights dim, suspect bad battery cables or excessive friction in engine. If not,check voltage at starter.

That happens on a lot of cars. It's natural because of the amount of juice the headlights draw. Only thing you can really do is to adjust the dimmer switch on your dash. All 3 of my cars do that.

turn on the headlights and try to crank the engine; if the lights dim out while you try to crank, then the starter is ok but the battery is too weak. just turning on the lights does not mean that the battery has enough juice to crank the engine; a starter pulls a lot more than lights. If the headlights do not dim out and it still won't crank, then the starter or a connection to the starter is your problem.

The starter will click like that when there isn't enough juice in the battery to turn the car over. Try jump-starting it, take the cables off the car right after it starts. Turn on the headlights right away. If the lights are dim or go dim after 5 minutes, then you need a new alternator. If the lights stay bright, drive it around for about 10 mins. Turn the car off and try to start it again. If it clicks again, you need a new battery. If it starts up, you're good to go - you must have just left something on and drained the battery.

try replacing ur altinator usually when u lose power or headlights go din it usually means ur alternator has lost its charge and will not hold up enuff juice to keep ya car running.

Starting car in garage turns on headlights which makes believe it is dark out and therefore dims dash lights. When car is out of garage it switches to running lights which allow dash lights to get brighter. I guess I should have figured that !!!

check the alternator charge level .
check the battery + and - are not lossing
if nothing then you have wiring short

Had same problem. Get manual diagram for starter assembly from manualspace.com. Tap starter assembly sticking out driver side of engine block with ballpeen hammer, or similar small hammer. Try a few times. Probably will restart, but need to replace starter assembly. Aloha!
