So, last friday when I was driving the "Check engine soon" light turn on, I drive for a while and it did not turn off in 10 sec like usual, then I realized that voltage meter shows very low voltage and speedometer has stopped working ans showed zero.

I finally stopped and look to the engine compartment, I found out that wire bundle have twisted around drive-axle and tear broken.



Generator wire was slightly damaged and the small brown wire cut off


Both transmission wires tear off, VSS and reverse switch


Some broken wire


I found where the broken ends of these wires were


Thankfully, I was able to locate all 5 broken wires and rewire them, everything seems to work again, and this times the wires are attached with so many cable ties they should not drop to the drive axle again.

Good job getting it fixed up, I'm surprised it didn't just stop running altogether. Hard to believe so many wires could be damaged and you didn't hit anything 'critical'.

Thankfully it was not as bad as it first looked. There were only six wires damaged, the two that goes to the reverse light switch, the two that goes to speed sensor and two generator wires. I was able to rewire with the help of Haynes manual and that I own second Fiero wire harness, I bought it together with lot of other used Fiero stuff from a guy from Helsinki last year. I did not want to cut any wire from the second harness, in case I need it some day, but I had to take the VSS connector from that since it was lost after this accident. When the axle rip these wires off it seems they did not damage any neighboring wires.

I did not feel any pull when the accident happen.

Voltage drop was apparently caused by short circuit with the drive-axle, since the skin of the thick red generator wire was rubbed broken and copper was exposed, however when I straighten the wire the car started and voltage return normal. At the moment I only fixed the skin of this wire with electric tape.

I thought that I should report this accident, since I have not heard others having similar. Anyway, I guess people should check the attachment of these wires, so that similar wire bundle drop to the drive axle does not happen. I personally decided to add a lot of cable ties to all wires and bundles that hangs around the engine compartment just in case.
