Electrical problems $4K to fix??

I would certainly check the hidden 125 amp fuse first.

 

^Yep, if the inverter pump shorted or any large current draw could pop that 125A fuse.

why does the fuse box and wiring harness need replacement? Can't they get one from a wreck; because that isn't a normal failure item. Was there rats/mice infestation involved or did someone reverse polarity jump the car? If it was simply a reverse polarity jump - fuse replacements usually fixes it. That's literally the definition of a fuses JOB....... Are there visually melted wires?

IMHO; I wouldn't get involved in something I can't see, hear, smell or diagnose - much less argue with someone over the phone while the guy is standing there looking at the car. That's the definition of a back seat driver or arm-chair quarterback.

 

Yeah I don't have a generation 3 here look at anymore. But I've removed fuse boxes out a 2 gen2. They much more modular than the 3 I guess . Wen flipped the Gen 3 do t allow you to literally unplug all the receptacles from it . Or something.

 

Anybody got one of these fuse boxes out laying on the ground FLip over take back cover off if it has one . Pictures ?

 

Spend enough time disassembling and removing the modules that are removable and you kind of get to this:



(out of the frame are four other relay-socket modules that come apart from this big one but still are direct-wired parts of the harness).

It's looking like if you really wanted to replace a fusebox and not the whole harness assembly you wouldn't have to make more than 70 splices maybe. Doesn't sound like a job I'd want (and I wouldn't be sure 70 splices would fit back in the enclosure).

Alternatively, it's clear that at the factory they crimp the fuse terminals onto those wires and click them into the right positions here. If you feel your terminal-extraction-fu is strong, you could consider extracting them all and clicking them into the right positions of another fusebox. But I guess if corrosion of the original terminals was the problem, that wouldn't be such a promising idea.

 

Ask if the $4k quote describes all labor till fixed? Or is a worst case quote? Try to find out if the bill could be less or more.

And then think if the car has enough value to pay $4. and touch so many circuits that some other thing could come up over time.

Is the car actually worth spending that much or does it have parts value?

Anything odd before the failure? Like run out of gas and then run down the hybrid battery?

Any codes being thrown? If so what?
