-Kind of surprised i'm having trouble with mine. I have been in contact with the manufacturer and he had some great suggestions.
-Bought a Tiny Tach TT2A to find out where my max rpms were on my 96' XP. It works great for about 15 mins then the rpms go up to 13k-18k its as if this tach is picking up interference or "noise" from something in ski and driving the signal crazy. I do have it set at 180 degrees setting, and I have tried the other settings. I do have a clean solid ground to block with the white ground wire, and I checked continuity from ground to ground and its good. We did discuss that the ignition system does fire both cylinders at same time on these 2 stroke skis, and it doesn't matter which spark plug wire you connect to either cylinder.
-Initially I had the red signal wire wrapped 6 times around the MAG cylinder spark plug wire. Took it out, was fine. Idle in water at 1560-1600 rpms. Rode around then it acted up. Brought it back to dock, undid my nice electrical tape and tie wrapping job
lol. took 2 turns of wrap off and made it 4. It did it again. Went back to lake next day and now i'm all the way down to 1 wrap of the red signal wire around the spark plug wire and its still doing it :ack:
-These tachs have been on sea doos since early to mid 1990s. I know i'm not the first one to run into problems but after much searching i'm finding some discussions on it but no solid answers.
-I am curious how others have theirs wired?
-The manufacturer has stated that I need to wrap the solid core red signal wire around both spark plug wires, and to start my wrap where the red signal wire comes out of the heat shrink. It is pretty long, so he stated to wrap it 1-2 times around both spark plug wires, and then trim excess inches and wrap a couple turns around itself at the heat shrink tubing sort of like a neuse. He said that me having that long red signal wire out in the open that it is causing it to pick up unwanted interference. I am going to try those suggestions this weekend.
-I will get some pictures up here soon.
-Thanks,
Rob
