My older Yanmar 3 cylinder engine has a tach sender on the bell housing. My Yanmar tachometer isn't working. I have tested the sender and the wires to the tach and it all checks out. Over the weekend i started the engine for the first time in 8 years or so and it runs great. If the tachometer is bad do I have to replace it with a OEM Yanmar tach or can I buy another brand?
