The battery died so I jumped it but it still won't start.

Customer Question

The battery died so I jumped it but it still won't start. There's power now but that's it
JA: Have you checked the battery, particularly the terminal connections? Are they corroded?
Customer: I did, they are covered so it's hard to tell
JA: What is the model/year of your Buick?
Customer: 2006 rendezvous
JA: Are you fixing your Rendezvous yourself? What have you tried so far?
Customer: Nothing, just looking so far aside from jumping it
JA: Anything else you want the mechanic to know before I connect you?
Customer: I don't think so. Thanks!

HI,

Ok, does the engine turn over, or no noise or just a click when key is in crank position?

Is the security/antitheft light on?

Customer: replied 4 months ago.
Just one click. Yes the security light flashes but only when the key is in the off position

HI,

Ok, there are several fuses in the engine compartment fuse box and a couple of relays you need to check - see attached

For the fuses, see if they are blown and for the relays, swap them with others in the box

Then there is one fuse in the fuse box located at the center console - see attached

If fuses and relays are good, you will need a voltmeter for some testing

How do I tell if they're blown?
Customer: replied 4 months ago.
Never mind got it :)
Customer: replied 4 months ago.
Still nothing. .
Expert:  Eric replied 4 months ago.

They have a metal filament in them. For the 2 blade ones, you will pull the fuse out and look to see if the filament inside the plastic case is broken. For the square ones, you can look at the top of it to see the filament and see if it is broken or not

I have a motorcycle master battery charger. When I hook it up to the battery it says it's fully charged

HI,

Ok, you need a voltmeter which is used for testing voltage at components, connectors and wiring. We need to see if there is 12v on the purple wire at the starter while the key is in the cranking position

Are they expensive? I'm a student and I just spent all my money on the vehicle that worked fine 2 days ago..

Hi,

You can get a cheap one for $20 at Walmart

Since fuses and relays are fine, there is no way to diagnose an electrical issue without a voltmeter
