Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Just to clarify you're saying you turn the key to the on position nothing illuminates on the instrument panel? Do the headlights come on? Do you have a jump box to jump start the battery? Did you have the battery tested? Do you have a voltmeter or 12 V test light to run some checks?
Provided that you did not jump backwards it would be extremely unlikely that any main fuse blew. I suppose if the battery was severely damaged or low the alternator could've overcharged and possibly voltage spiked the large 120 ALT fuse. This fuses wired into the fuse box and in order to replace it the box has to be disassembled and the fuse un bolted. Let me know you find the power to the fuses under the hood.
That Is what I was afraid of If the battery was even close to being salvageable or rechargeable in the short period that you drove it it should of recharged it even to about 11 or 12 V. I would replace the battery with a new battery and then see how things go. It would be extremely rare to see the alternator below that fuse simply because the battery is dead.
Yeah I know that ass freezing feeling also. Let me know how it goes or if you need any additional information for free to reply. If you have not done so please not forget to rate the assistance that I provided you at three or higher.
