I recently changed my lower shift cable on a 5.7 Chevy/Alpha One Outdrive and when it came time to adjust the cable I discovered that the 2 wires running from the cut-out switch were metled by the exhaust riser and shorted together. I replaced the 2 wires with new ones and when testing the switch with a multi-meter it always reads as if the switch is closed. If I take one of the wires off the mounting terminal then the switch reads open until you press the lever in. The manual shows the brown wire goes to the negative side of the coil and the black wire goes to engine ground. The problem I am having with this is if you measure the continuity from the negative terminal on the coil to engine ground it always reads 0 ohms??? What is the purpose of the switch then?? The boat shifts into gear with no problems and better then it ever did before so I am dumb-founded as to how this is working? I know electronics pretty good so the only thing I can think of is that the engine ground is different than the battery ground? There are 2 other wires on the negative side of the coil, one goes to the distributor (which is grounded to the engine) and the other goes to the tach in the dash. What purpose then would it be to have a switch in-between engine ground and the negative side of the coil when its already grounded?? I hope you can make out what I am asking...sorry for the long question.
