alternator replacement

[david_12121]

so i put a new alternator in and i've ran to a problem
power steering, parking brake, brake, and battery lights are on in the dash, but they all are working properly

it all worked fine until i got home and had to park...the serpentine belt fell off then...had to put it back on cuz i don't have the strength to turn the wheel without that!

so what have i done wrong that all those warning lights are on?!
why did it fall?!
(it did charge the battery tho)

thanks in advance

Make sure that you tightened everything in the tensioner assembly properly. I once made the mistake of forgetting to tighten the 12mm nut that holds the tensioner pulley tight. It backed itself off, and I had to put it and the belt back on. From the sounds of it, something definitely wasn't tight enough.

David,
did you check all of the pulleys to see if they spin freely?
This of course is done with the engine off, and the belt removed.

Also check to see if the crank pulley is separated. There is a rubber layer between the two metal layers. If you paint a line across the 3 layers, then run the car it will be real easy to see if they are staying together.

i'll tighten it more that last time to see how it goes...do i have to tighten it just to take the squeal away? how would i know if it's tight enough?

changed the timing belt a few weeks ago and i checked the crank pulley too...seemed very solid actually...


What about the warning lights? can it be that the connector to the alt is messed up?! cuz i wrestled with it to take it out....freaking subaru connectors

Could be that the new alternator is bad.
