I have a 69 Rude on my Larson, I have replaced the amp on it plus the coil. It ran last fall but when I went to start it this spring it has no fire. I have gone threw the tests that it calls for in the mech. manual and don't have any juice coming out of the amp, according to the test. Is there anyway I can test the amp off the motor and see if it is good. I used a tester and found that I have continuity between the base and the grey wire, and the base and the blue wire. It records clear over when I touch the wires and the base. Is my amp shot, it seems like it must be shorted out if there is contact between those points. I'm not much when it comes to new fangled things like that. But now a friend gave me a boat with a 74 Johnson on it. It is froze -up but he said the electrical worked. My quesstion is , can I put all the electric off the 74 onto my 69 ???? Or can someone help me with the old elec. problem on the 69. Thanks
