wires getting hot... why?

Eliminate your ammeter,undo the 2 wires on the back and join together.Or you can search in the electrical forums,some good threads in there!Or you could private message a member here..Redfish,the guy is a Mopar electrical geniuse in my books.Good Luck and hope you don,t have to use the fire extinguisher!Sorry for the poor advise on the ammeter,drinking lastnite.Other guys will give better elec. advise!
