I have recently replaced a 75 hp Mariner motor with a 65 hp Merc. 3 cyl. along with the remote. When I started the engine the Tach would not work. It was connected through the connector on the front of the remote. (Brown wire) That wire ohm tested good with no short to ground or power, to the switch box. I ran a jumper wire from the rectifier to the tach signal lead and the tach began to work. My question is, can I run it like that or will I damage something? Also, if I am getting no tach signal from the brown wire on the switch box, is it bad? or do I just have the wrong tach?
