Fried electrical? Or just a fuse?

145

Asked by Feb 11, 2014 at 02:12 PM about the 1988 Toyota MR2 Supercharged Coupe

Question type: Maintenance & Repair

I was helping a neighbor who had a dead battery. I was giving him a jump and he connected the battery cables to the wrong terminals on my MR2. The MR2 continued to run but after I turned it off it was dead. No dash lights, nothing. So did we blow some fuses or something more serious? I had to leave for work so I left it there. Haven't had a chance to investigate.

it could be anything from a popped fuse to fried wires, could even have fried the ECU. Look at the fuses first, if all are good start tracing wires, if you can't find any bad try testing the ECU. Odds are it is one of these things that has the issue.

It was just a fuse. $3.39 later and she runs like a top.

I'm not sure what fuse would affect the speed and tach. I believe those are operated by cable and are old school mechanical, not electronic.
