so I've made a big mistake and the reason my car wont go into ready mode is because the inverter wires touched while the 12v battery was still connected can anyone direct me on what fuse or relay I will have to change to fix this ? I've checked all in the engine compartment and they are good or any component that may be damaged
The orange high voltage cable? Do you have 12v to chassis at the engine compartment jump point? If it was not the orange cables, trace the power starting at the fuse box.
Specificity will be helpful here. Which wires touched? Did they touch each other, or something else, or both? (There are a bunch of wires to the "inverter".) How did they come to touch? How long did the touching last? What state or states (off, acc, ig on, ready) might the car have been in while the wires were in contact?
If you shorted wire 1F that connects the inverter 12v to the 12v battery, your 125amp fusible link buried inside the engine fuse box is blown. With a flashlight at an angle you can see the link You can also check for 12v downstream of the 125a link. One location is the 30A Eng WP (Engine Water Pump) fuse
Yes the orange cables the two closed to the fuse box touched each other for about 15 seconds I removed the inverter to change the pump and forgot to disconnect the 12v battery I was moving them to take out the coolant bottle when they came in contact with each other when I heard the hybrid noise I realized and separated them then
I think I finally recognize it even after I previously took the box out. So. An you please tell me how do I check it and if blown how can I fix it keep I. Mind I’m outside the US on a small Caribbean island with limited resources
I will assume your short was 12v from the inverter to the fuse box. The 125a fuse connects that point to the white battery cable. In post 2 the diagram shows another 140a fuse link at the battery in the 12v terminal. Check it as well. A voltmeter check before tearing it apart would have quickly isolated the problem. Part number in pic of new part. The fuse box comes apart in sections but not easily. Verify the 125a using a meter first. See "12v Test Point" in pic below. With the fuse box out it might be easier to use the meter in ohms mode between the two points. Continuity (0-2 ohms) would suggest the 125a is good. If use of a meter is new to you find help.
You say you hadn't disconnected the 12V battery, but you don't say whether the car was off, acc, ig on, or ready at the time. It's hard for me to imagine you doing a job like this with the car anything but off, right? Of all for states the car can be in, only in READY do those orange cables have any power on them. It's hard for me to imagine you'd start taking those off with the car in READY, right? Moreover, to disconnect those cables, you have to remove cover panels from the inverter that have safety interlocks to keep the car from going READY. It's customary to also pull the orange service plug at the traction battery before working on those cables at all. That plug also has an interlock to keep the car from going READY, not to mention it also brute-force interrupts the high-voltage circuit. So if you had followed the usual customs, there'd be about five reasons for those cables not to have any power. Even if you skipped a couple steps, there were still probably two or three reasons those cables didn't have any power. So I am pretty comfortable saying those orange cables briefly touching wasn't the cause of any trouble you have now. But I'm intrigued by what you call "the hybrid noise" you say you heard. Can you describe that noise some? If you really had touched those orange cables together with them having power, from some freak failure of all five reasons they wouldn't, it would have been spectacular. For you to post about it on PriusChat afterward would be amazing luck.
I unpluged the safety plug from the hiybrid battery removed the inverter then i tried to move the orange cables to the out the collant bottle the cables touched then I heard a screeching noise which made me realize there was power in the cables ran to the truck and realized the 12v battery was still connected once I put everything back together the car will not start
Ok, solving the issue that you have now will probably go faster by focusing on what might have caused it and not on what can't have caused it. As you did take the orange service plug out first, there was no power on those orange cables, for all five reasons. The screeching noise you heard, therefore, was related to something else, and the current trouble may it may not be related to that.
Once again, use a meter to check that fuse. If it's blown you then pull the fuse box out and apart. Get some help that knows how to use a meter.
