do you have a voltmeter or at least a 12 volt test light?
if so, do you have voltage present at fuse #BATT 1 in the underhood fuse block, mounter to the right front strut tower?
To answer your question about the starter, no a bad starter would not cause you to loose all electrical. Here is the power distribution wiring diagram, if you don't have a voltmeter or at least a 12 volt test light, I see that the radio is almost a straight shot from the battery, so does the radio work or at least come on?
While you are at it, check those BATT fuses in that underhood fuse block, cause they feed the I/P fuse block.
1 volt is no good, 11 is ok.
Is that 1 volt on both sides of that batt1 fuse or just one side of the fuse?
I am assuming though the battery is only at 11 volts, is that correct? If not, batt 2 fuse should be whatever the battery reads, no less than 0.2 volts less.
No, that isn't the way you should hook up the voltmeter. hook the negative lead of the voltmeter either to a clean metal ground or the negative battery pot if it will reach that far, then touch the positive voltmeter test lead first to one side of the fuse and then to the other side of the fuse and make sure both sides of the fuse have battery voltage (12 volts) all the time, for those BATT fuses that is.
1 volt on both sides of the fuse? Did you ground the voltmeter like I said?
I think you have a bad fuse box. If you remove it you may see the problem, probably some rust maybe or it burnt through underneath.
replace both of those fuses and check them readings again.
maybe it's not the fuse box then.
no that is not what you asked, you asked, "Can a bad starter kill all electrical power to the car?" Either way no, the starter relay could not cause all of the power to go out, unless maybe it blew a main fuse.
What do you mean by, "when the starter relay is disabled"? How are you disabling it? If removing the fuse, then if that fuse also feeds something else, it too won't work then.
It's the relay that powers the engine control module among other things. it's on that fig 4 of the wiring diagram.
They should unless you were hooking up the voltmeter wrong.
from the readings you gave me, both of them fuses were blown.
You said, "I have 11.5 v o bottom terminal and.5v top terminal on batt 1. batt 2has same reading on bottom term but top terminal is 0 v' First of all, I assumed you meant .5 volts when you said, "batt 2has same reading on bottom term". anyhow all readings should be 12 volts.
