Worst thing you did or encountered?

Ditto on that, this will fail. This is the kind of things that give us all bad names.

I have 2 .... Doing a simple keyless in (of course) a friends S-10. Attempting to find a nice neat place to hide the relay pack. (added actuators) dropped the relays......catches on some metal brace under the dash, snap, crack, the smoke starts flying as the wire melts all the way to the 12v t-tapped connection, then the main ign. harness starts smokin...... Holy crap. I couldn't rip those relays out fast enough. This is when I learned to wrap the relays in tape. Not to use t-taps, and solder

Puttin a deck in an old Ford manual trans (OLD) lifted 4x4. The truck has no neutral safety, and a bad ign switch. Understand, the shifter is like 2.5 feet long, and has about 3 feet of "throw" (both directions.) So I put the shifter out of the way, commence to hookin up wires...... never worked on an old rig like this before (years ago) time to turn the key and test for switched power.......cranks rite over, the rigs in reverse. Plows right into a new at the time Honda van. I had had a tough day......this was the straw that broke my back.  The shop is L shaped, the truck was on the bottom of the L it flys back and tore the entire front of this van off. then plows thru the sop wall into the next doors shop.

I didn't need to get up the next day for work.........

is it just me or does nothing above me make sense

Workin on a Freshly Painted 69 Camero SS stolen recovery in a paint shop surrounded with other cars that the squeezed together in this tiny shop when closing up 4 the night, I was replacin the ignition switch, forgot about these old cars being able to start in gear.. on the passenger side layin on the floor across the trany hump and turn the ign to start to test it.. Camero jumps ahead, 454 by the way, luckly i open the hood about a foot, went crashing into a paintbooth heater/vaccum system (probably an expencive thing), only thing i messed up was the hood it caught all the force and bent a bit, but not a scratch on the bumpers or grill nothing.  Paint booth was still workin fine...Shop owner told me the customer wanted a cowl hood anyways so i didnt have to pay anything.   Close call on a

2nd Same shop doing another ignition switch 64 stang, ignition was workin perfect, shop owner says i cant start the car.....  I get there, check my wires looks good, check for 12 @ starter none.hmmmm check my wires again, 12v out 4 start, but wasint getting to the starter back and fourth, back and fourth.   Deside to crank it over manually with a jumper wire, car starts and drives in reverse right into my freshly painted rear doors of my Astro, I was parked maybe 10 feet from it. Guess this car did have a saftey switch.. atleast it was my van i ran it into.  But u should have seen me try to hold onto that mustang like i was going to stop it, i held on all the way hahah. Mustang was fine rubbed some of MY paint off with steelwool.  Still havent fixed my van, Shop owner Still calls me to do work  :)
