This has not been my week. Bought a new Kysor/Medallion tachometer from Great Lakes Skipper. Came in Friday. When I took it out of the box I noticed that it was reading 1,000 rpms. They tell me that tachometers come set at different rpms and to hook it to a positive lead and it will be ok.<br />Does not sound correct to me. Or am I wrong.<br /><br />There was no documentation with the tach so not sure to hook it up. Looks like one lead to the light and one lead from the motor to the single post on the tachometer. Where does the tachometer hook up on the engine.<br /><br />Thanks for all of the help in advance.
