...alternator is completely dead.
I changed the battery, nothing. When the door is open it will
give a weak "ting ting" noise, but even the power locks on the door
I am trying to get the alternator out of the car. I need to find an
idler pulley to loosen the belt so I can remove the alternator.
Can anyone help me find where this idler pulley is?
Eveything ran good until someone jumped the car wrong. I just
want to try and fix it. .
A drive belt will pass through several pulleys, to drive accessories
such as alternators, power steering pumps, and AC compressors.
There is one extra pulley not attached to any accessory. This is
the idler pulley, used to apply the proper tension to the belt. Idler
pulley tension must be relieved to allow work on the accessories.
If the bad alternator is disconnected and a good battery is installed,
everything should work (until the battery runs down). That wrong
jump may have damaged something else.
Ask a friend who has experience to advise you.
