Car wont start - help! - Toyota Yaris Forums

tamo300 · 03-23-2010, 03:22 PM

Thank you very much indeed for all of your help - it's really appreciated.

I have purchased a booster pack to charge the battery. I was wondering what the following means on the booster pack instructions) attach the red cable to the positive on the battery - this i understand - BUT what does it mean when they say attach the black to an EARTH POINT on the engine - attach it to a non-moving metal part on the engine?...i'm a bit confused.....

...or can I attach it to the negative on the battery? (the booster manual says not to but attach the black to an earth/metal point)....

...also, in the Yaris manual it says that when recharging the battery whilst still in the car, the GROUND CABLE has to be disconnected....um,

what is this ground cable, and do I reconnect it after the booster has recharged the battery?

I had a car that kept killing batteries,found out it was the light in the trunk not turning off, ever since i remove the bulb from the trunk light..To check when you open the trunk immediately feel the bulb if its hot then its staying on.
You also may have dirty battery terminals,take off the battery connections and clean with some sand paper or small wire brush,do the same to the battery posts.
Another maybe is the interior cabin light is staying on,turn it off..
PS Are you using the same ignition key everytime as one of the keys i got when i bought the car only opens doors and wont start the car..

Add-ons like stereos and car alarms often drain batteries.

EARTH POINT on the engine = Yes, Any part of the engine that is not painted, and does not move when the engine is running.

Disconnect the ground cable = remove the Negative Cable of the battery and connect the Negative (black) cable of the charger to the Negative battery post. This ISOLATES the battery and charger from all of the other circuitry in the automobile. Some circuits are sensitive to sparks/surges and could be hurt so the isolation will assure that never would occurr. BE SURE THE CHARGER IS NOT POWERED ONWHEN YOU ARE MAKING THE CONNECTIONS ! POWER IT UP AFTER YOU RECHECK THE CONNECTIONS FOR POLARITY, ETC.

Hope this helps you !

The alternator could be faulty. That would explain why the car started once and then wouldn't an hour later. How old is the car?
