If you can't fix it with a hammer, you have an electrical problem! (spoken by a guy with every GM factory certification except automatic transmission repair and roughly $30,000.00 in tools) The stuff mentioned so far is great but I have to admit the thing I find myself reaching for more often than not on "rescue repairs" is flashlights. Sometimes lots of them!
As seen several times on many of his home repairs. His hammer is one that even the mighty THOR would envy to own. Unfortunately every time he tries to pound / fix something with his flashlights it looks like a 70's disco for about the first 10 seconds then it goes dark. Then he reaches for the hammer, sparks fly and it is announced that it is an electrical problem and it will have to wait till the morning.
Rantor is my hero. hahahahahahahahaha (love ya brother)
