Dead start Sign In

Hope someone here will have a quick fix, LOL. Ok my daughter has a 2006 Caravan 3.3. Don't really know if this has anything to do with the problem, but thought I would add. About 2 weeks ago she gave another girl a jump. Well they hooked the jumper cables backwards. The cables started smoking and they removed them. One side of the cables actually melted. For about a week her Van was fine. Then she started from time to time needing a jump. At the time I didn't know this happened. Well she got gas the other day and when she pulled out the Van revved up and died in the middle of the road. She calls me. I get there to give her a jump and the negative battery cable is melted about 4 inches down from the post. Had the Van towed to her house. When I get there I checked the battery has 3 dry cells. Took the battery out and got a new one. Fixed the negative cable. This is when the funs starts. Installed new battery. Put the key in the ignition. The door bell chimes. Turn the key to on. Everything works, windows, AC/heater fan, radio, windshield wipers, signal lights. But no instrument panel lights, dead. Go to start, nothing but a low click sound from the fuse box under the hood. Checked all fuses and relays, all seemed good. Plus I noticed no fuel pump hum. Well I jumped the starter relay and the engine turns over fine. Jump the fuel pump relay and the fuel pump spins up. So both work and getting fire. Look everywhere I can see all connections from battery and to fuse box, nothing else looks bad. From another forum the I guess you call it the computer could be shot, shorted out. The metal box on front of the fuse box. Replaced it, nothing, the same. That's about where I'm at. Comes down to a dead instrument panel and when you go to start, nothing. But everything works when you jump them. My next guess was the ignition switch. Thanks for any help.

Wow - disaster apparently. Time to "unlearn" any attempts to jump start a vehicle and use only jumper boxes NOT another vehicle anymore. This was worse now the melted wire, burned up items I can't think of a quick fix to even move it again.
Why? This is a computer on wheels, worse a "Mopar" or Chrysler product controls everything thru computer control not just one but many things. Many need to be programmed to the DNA of this exact van not just replaced.
For now I suggest just disconnect (negative first) battery so this thing doesn't just catch fire.
Take that battery OUT you already know it's junk don't let it spit acids all over making the area even harder to deal with. I didn't know of any recent battery types you could even test or see the "electrolyte" level of anymore they should be sealed would be busting caps to see if there. Doesn't matter now you know it's done.
Dry cells? OK where did that acid go? I envision a total nightmare scene around this be careful of that mess it will burn YOU, harm YOU or more around that area to mitigate that use baking soda with batter GONE. If you smell it or fuming cut the neg cable and go away with hood open till it's stable have the van OUTSIDE not in an enclosed area.


That's it. This is damage control about like an accident there's nothing fast to do now unknown how much was wrecked and what it will take at the moment seems nothing to work with.


Decide if you wish to learn and be equipped for this van or where you want it to go to fix it.


I know - I make it sound dismal but your report of events isn't very encouraging for anything fast now to fix this. At least don't get acid burns on you or anyone,

Re: Dead start Sign In

You need to test ALL FUSES AND FUSIBLE LINKS using a test light. Also check for all the body grounds to be in tact.
Also have that new battery tested. It could be bad.

This is probably one of the worst things you can do to a car. The damage can be anywhere.

Re: Dead start Sign In

Pretty sure the new battery is good. Like said if I jump the starter relay the starter turns the engine over fine. As far as the fuses, I took them all out and none is burnt. The starter relay and accessory relay are the same, accessories work, so I put the accessory relay in and still nothing. The horn works and the relay is the same as the fuel pump relay. Swapped and the same nothing. But if I jump the starter or fuel pump relays both work.
Now the fusible links, have no idea where they are. (will look those up and check them) I checked the main ground to the engine, its looks fine. Which I guess it is or nothing would work.
Dummy downed. When I turn the key to on, everything works, from windows to fans to radio to wipers, but no instrument panel lights, but other dash lights work. When I turn the key to start nothing but a low click in fuse box.
I have this weird feeling the no instrument panel lights is the root to where the problem is.

Re: Dead start Sign In

This vehicle uses maxi fuses instead of fusible links.

If you are sure that you have all good fuses, tested using a test light, then you may have burned out the IPDM (smart fuse box)

Re: Dead start Sign In

After reading your post I started looking around about fusible links and was looking at fuse box diagrams and saw it has a auto shut down relay. I never checked that one. It seems the symptoms seem pretty close to the same. Not at her house right now, going back tomorrow, will check that.

As far as the IPDM (smart fuse box)
I took the whole fuse box out and checked the connection on the bottom and they seem fine. But that's doesn't cover connections wiring to the fuses and relays on the inside I guess. Will look into that too. Thanks

Edit
When I changed the what I call the computer, the silver box on front of the fuse box. It was supposed to have come off the same year and model and engine.

Re: Dead start Sign In

I'm not talking about connections. That fuse box has an internal module (computer) that turns these relays off and on. Your power surge could have easily fried that.

Yes, the ASD relay powers most everything for the engine including the injectors and fuel pump relay.

I replaced the one on front of the fuse box. So there is another one inside the fuse box?

Re: Dead start Sign In

The box itself is a module.

I have no idea if that will fit. You need to match up part numbers and it may need programming.

Re: Dead start Sign In

Going to check that relay tomorrow. Then check for any other damage. It says its compatible with her year model and engine. Will try that next. Will post back tomorrow and tell what happen or not happen. Thanks for your help
