Default i just blew 11 fuses.... wtf ?

last night, interstate driving, 80ish, all lights start flashing wipers start banging away as fast as they go, sparts and flashes under the hood, raido flashes off and on, all pop at once then everything goes dead, no brakes, no lights, no power, in the passing lane, cut through traffic, way off to the side, almost in the dirt.

what just happened ?

i blew 11 fuses, burned out some half a hoop thing (dont really know what it was, just had burned little nubs left. made a wire jumper for the half loop thing, and replaced all the fuses, wont start.

all the lights turn on, and all the power goes were it is supposed to, i blew out my wiper motor, or just jammed it in place... havnt checked yet.

i pulled the fuel line from the filter and turned her over.... no gas. didnt hear the fuel pump, didnt hear it laying on the ground listening.

if i could have burned out my wiper motor with this little flash, couldn't i have done the same to my fuel pump ?

how do i test my fuel pump ?

any other ideas ?

thanks, i love this place !

Sounds to me like a major short or something along those lines. Most likely (my guess) your positive from the battery touched a ground and shorted EVERYTHING. Check to see if you can find any electrical burns on anything...

That or aliens.

didnt see any lights outside the car, except the cars around me..... i have been tearing it apart, looking and smelling...

some kind of electrical burn smell, cant find it.... i have taken some of the dash and stuff apart, on the ground up under the car, snif snif nothing....

come on... someone has had to know what is going on....

I suspect the problem was caused by shorted diodes in the alternator and the systems got hit with AC voltage. I would remove the alternator and have it tested before starting the car again with it in place. Have the battery tested also.

The small half loop of wire you replaced with a piece of wire is a fusible link and you need to replace it with another new one. You face the risk of serious damage if you leave that wire in place and have another problem.

If things did get hit with AC voltage the ECU may have been damaged and you may have to replace it.

i would NOT want that happen to me after watching X files...

I would lean towards Cougar's AC explanation too. Had it been a +ve battery to chassis short, the battery would have simply blew up. Had it been one major short, one major fuse would go away. In any case, it would have been a single flash/fuse melt/ burn. All that flashing and alien behavior does testify to severe voltage fluctuations, without immediately drawing the current up the roofs.

I take it you didnt get hit by lighting though?

The alien explanation does sound better I must say. "Muldor, on line 1".

shorted diodes should not cause massive AMOUNTS of current to flow through the system, and likely not even AC current as the diodes only serve to cancel out half of the phase on the three coils, should one or two or even all of these short out it would lead to almost no voltage as the phases of the three coils would cancel out.

Short of aliens I would suggest checking the wiring underneath/behind the fuse boxes, or a wire that overheated melted and shorted to ground. just keep looking for something this big you should know when you find it, you'll likely find some burned chunk.

I believe Schrott will find out the alternator is toast. The internal regulator at least had to blow out for this to happen and I think the ECU may be smoked also, but hopefully not.

To ProdriveDreams:

After reading your post I had to sit down and really think about what you said. I know others have measured AC across the battery at times when the alternator is bad. After going over this for some time, I think if the right combination of the 3 phase diodes are open and shorted then AC will get across to the battery.

Cougar4 I suppose a small amount of AC might be possible but it would be very low current which still would'nt blow fuses, but you might very well be on to something with the blown regulator... It would be a good idea to remove the alternator and get it tested before running the car anymore. Make sure where ever you go doesn't just run an output test on it you want them checking the wave pattern with a scope as well. A good shop wiill put it through its paces.

also as far as testing things it is possible you blew out both the wiper and the fuel pump motor. Are you sure they are both recieving power? you could always test the motors themselvs by just applying 12VDC directly to the motors.

Default kind of good news

thanks guys, i love this talk to thousands of car guys at once thing... !!!

ok, well i have another alternator from my other engine, swap. i need to go junk yard diving and get another under hood fuse box, a little meltdown action....

i have been looking all over this stupid car for some kind of flash burn, melted wires, plastic spatter, i cant even smell the burning anymore....

what is the wire half loop called, so i can go get another couple ?

so glad i have a box o' fuses....... had a box o' fuses.

i did just wire in a harness for a hitch, i know i did that right, but i tore it apart again to check, everything looks fine, lights still work.

i messed up my ignition switch...... almost identical keys, wrong one went in but wouldn't come out......... a little, gentle persuasion, did the trick. now it only has aux, and start. i have to leave it in aux, then disconnect the neg underhood.

could the connecting and disconnecting of the negitive batt cable have anything to do with this ?

thanks

b

As I stated earlier, the wire loop is called a 'fusible link'.

You now state that the power distribution panel under the hood is damaged. In that case it sounds like there was a severe short to ground at the panel.

I don't see any way this damage was caused by you removing the negative cable. I do recommend you fix the ignition switch problem though.

i have another complete switch assembly on order.... stupid cars, take all my money... who am i kidding, i love it.

the ground looked fine in the box, were the fusable link blew, it melted the connecters into the plastic around it... i already got another box.

i just asked this question in another post, but, were is my ecu ?

Underneath the passenger side kick panel. You can't miss it.

Smile Fusable links

Couger 4 is right, those are fusable links, my wagon had one go out, and it shut down the electric fuel pump, and the power to the ignition at the same time. Once this is replaced, check everthing you don't have, power to the fuel pump,(no hum), the fuse for the pump may also have blown, and some wire may also have fried. I know firsthand how frusting these little problems are, just take it one item at a time, and hopefully your computer , (ecu ), is still OK-Z

replace all my fuses, alt, fuel pump, new fuse box under hood (including fusable link), coil pack, took out my trailor hitch harness, she cranks over, no starting. got a new battery (needed a new one anyway) after putting in my new ignition switch assembly, i tried again...... nothing..... and when i went back, my new battery was dead.

WTF !!!!!


soon i will try the torch and sledge method

If it cranks, and you hear the fuel pump then make sure you're getting spark.

Since your battery is being drained it sounds like there is a load on it that shouldn't be there. Do you have a ammeter to check current with?

Like TIC stated, make sure you are getting spark. The pump won't run without the ignition working. You should be able to hear it briefly when you turn the key to ON though.

found out my ecu was the wrong one... the one in it was for an automatic. new ecu.

my fuel pump wont turn on, still !!!!

i replace three more fuses, swapped out two relays........ whats left ? !!!!

this s@%t is getting tiresome........

im thinking all thats left is to gut the interior and start tracing wires....

I WANNA DRIVE !!!! damn it...

i think im going to blow up my volkswagen too..... hahahha toys, toys, toys.....

good thing i have a bicycle
