I have a 1995 Rinker Flotilla with 4.3L Mercrusier engine.
Just pulled the boat out from winter storage and now I now have an alarm with the Key ON. I don't recall exactly the Key On scenario last Fall, but I know it ran correctly without the alarm. I've done a handful of maintenance over the winter such as replacing lower unit impeller, oil + filter, gear lube, and installed a handful of electronics like fish finder, stereo, and Automatic Low Voltage Disconnect.
I've read dozens of posts on this and have now purchased the wiring diagram. According to the diagram, only the Water Temperature, Drive Unit Oil, and Oil Pressure Switch can/should trigger the alarm. They are wired together in a OR-configuration so that if any of them short to ground the alarm activates. Well... I disconnect all 3 and my alarm still activates!
I next disconnected the main wire harness plug in the engine bay and confirm the short to ground was in the engine bay. I'm not sure how this happened. I don't see any obvious damage from mice/rats. The wire harness is still wrapped in tape.
Any ideas where I go from here? My best idea is to instead of tearing apart the entire harness is to cut the tan/blue wire and then use new wire to re-wire each sensor back to the plug.
