Since the Altenator is run off a serpentine belt with an auto tensioner, this may not be the issue, although an old, stretched out belt could be the issue. If it's the original battery it may need changed or the altenator may be failing. Both of these can be tested for free at a local parts store, like Autozone, and I think they can do it while still on the vehicle.

You may need a shop to look at it, or get a used shop manual from Ebay to get the necessary wiring diagrams. The problems could be related, such as the key switch or the main wiring harness.

40 amp fuse labeled 'Fuse Block' is causing a 3.5 amp parasitic draw and draining battery


??? are you certain its that ??? that fuse will most likely control all the power in the fuse box and the 3.5 amp you see that's called the parasitic draw will most likely be that of the cars computer..

3.5 amp wont drain a battery over night nor in a week i'm assuming you have at least a 500CCA battery here.

battery's don't drain like that, they do loose power once they have a bad cell, or the battery water is low. I'm assuming you had it tested here by a technician from the battery shop and that's what they told you and its a new battery or relatively new..

to test this your self you can take the battery out of the vehicle and leave it outside over night, you will see the power is drained out and it wasn't connected to anything. Thats because of the bad cell..

To prove it to them, Remove the caps If its not a sealed maintenance free one and you will see bubble coming out of the bad cell once the car is idling.. (don't inhale the fumes or let it get in your eyes)

My toyota 4 runner will not crank & all my power is going dead


It could be many different things,but first remove battery,take to Autozone or Walmart and have them test it,if bad,replace.If good,or your alternator is bad and draining battery,check your belts to see if they are tight.Also you have a fusible link tied into the positive side of battery,follow all wires leaving positive battery cable for burnt or melted wires.To check starter,you must remove and take to Auto parts store to test.

if you have an autozone,they will put it on the computer for free.if you don't,call around some parts stores and see if they will.you should change the belt instead of shortening it.sounds like the alternator though.have a shop check the tensioner too.

How can I tighten the alternator belts on a 1992 Saab 900? I had a shop replace the belts and tightened, which worked for about a month. Now, the belts feel loose, they make noise when starting in cold...


The belt should not be stretching this soon. From what you say about the alt light lighting up every morning and thie belt making noise. this leads me to belive that for some reason your alt is going to full output first thing to make up for a low battery. So either you have a drain on the battery overnight due to something not shutting off at night, or your battery is going dead. Both of these conditions would make the alt have to work extra hard first thing in the morning, wich could put a strain on the belt causing it to stretch on you. I would take it back to the shop and have both your alt and battery checked before worring about the belt. Other than that, the shop that put your belt on should adjust this for free if they didn't get it right the first time and tighten everthing back down as they should have.
