ordered a tiny tach for my Yamaha 64x 760 in my jet boat for a few reasons... diagnostics, hour timing, and just to see what rpm im turning. Has anyone put this on a jet ski before? Just coil the wire around the plug, ground it, and your good to go?

I tried adjusting the # of wire wraps around the top plug, but no change. Would stripping the insulation off the cheap tach wire and putting in ON the plug itself correct the issue or not??
Mine does that too on a 18hp Nissan. Tried everything LESS the just "looping" it around the plug wire. Hopefully not a DUMB question - but did you use a big loop or small loop tight to the wire?TNtroller said:I have a amazon knockoff, and mine shows 2x the rpm's that the factory tach does.

I thought I was also getting readings from the other plug wire, as they are darn close to each other as routed.
