Subwoofer/alternator/timing Belt

[w34ponGT]

hey guys just a little question.

its weird how its changed. i got my daily toyota starlet and i got the timing belt changed and the other 2 belts.

now the subwoofer doesnt go as hard and my lights dim way more than it used to.. is there something wrong or?

im not sounding like a muzza bro with my subs but honestly its dropped dramatically and my lights dim way more to the bass lol

anyway opinions/thoughts

Is the alternator belt slipping? not tight enough? get a capacitor and a new alternator doof doof doof.

Just tighten the fan/alternator belt.

Thats a bit odd.

Something to check, other than the obvious tension of ya belts.

its a bit of a long shot but worth a look.

People commonly upgrade the earths to reduce headlight dimming ,, so maybe they have disrupted the earth somehow.

You will probably have an earth strap running from the block, to the body of the car. have a look around for that and make sure its still connected.

check that your battery terminals are clean and connected nice n tight.

check the connections on the back of the alternator to make sure they are all sweet.

Its either gonna be

1) your alternator output has dropped for some reason. ie: belts slipping

or

2) the power flow around your car has changed ie: bad earth, loose terminal etc

sounds good il have a look tomorrow cheers for that. i thought i would of got laughed at for this post but im being serious lol. how tight should the belts be.. how do you check for tension?

[cobbadan]

Cant really answer that one, i would assume that the correct tension would be , tight enough that they don't slip.

And i would have also assumed that, if they were slipping, you would be able to hear them squealing.

a quick google around got me this, im sure there will be more, out there in google land.

see the car handbookfor the correct method of checking the ten- sion. If one is not mentioned press the belt firmly mid-way between the two most widely spaced pulleys; there should be about 1/2 in (12mm) deflection in the belt.

1 check belt tenshion.

2 if the mechanic disconected the battery the settings on your headunit could have been changed.
