Bought my 2000 SD Challenger 2000 two weeks ago: Problem 1; speedo not working, saw the dial jump upto 40 twice while on the water, prior owner said they had same problem.....PROBLEM 2; GAS gage not working,but yellow oil light flashes once at start up....PROBLEM 3; I knocked three wires off the electrical block while checking starboard side fuse box (port sidebox is just six inches away), both boxes are on the electrical block behind the dash,below the storage bin.drivers side. anyone know which wire goes on which push on post (know the wire color that goes to each post, top to bottom?) Problem 4; is the bilge blower suppost to work with the key off? May have been one of the wires I knocked off ,,it now works with the key on, but it seems that it did work with the key off,,,maybe that I clipped a lossse wire to the wrong post ? Any reply would be appreciated
