Adding a tach

[MH Hawker]

I have decided to add a tach to my boat set up. I have a 1996 mariner 9.9 with a comander 2000 controler. This morning I picked up a tach and ordered the plug in cable to run from the shifter control to the consol. I have a print on the hook up and have reserched what the pulse setting should be. Just wondering if I was missing any thing.

Sounds like you have it covered.

Re: Adding a tach

My cable made it in today and I went out to the boat to do a test install before cutting any holes and ran into a problem. The tack needle was around 1500 rpm to start off and after I hooked it and fired up the motor the needle dropped down to 0. According to my motor book its a 8 pole/4 pulse and I had set the scale accordingly and I did try switching it around a few times, but no go. I did read DC voltage 4.5 at idle and it ran up to 7 when I lifted the fast idle leaver. Would I be right thinking the tack its self is bad.

My motor is a 1996 mariner 9.9 with comander 2000 control box.

The charging system if fine I just recently went through it.

Re: Adding a tach

I got it sorted out this morning. Yesterday when I went out to the boat I glanced at the print and saw the black- wire and the gray signal wire as connections and last night I took a closer look and it also needed the purple wire 12 +. Amazing how well it works when you hook up all of the wires :facepalm:

Thanks for letting us know. You certainly aren't the first to make such an oversight, and you certainly won't be the last!
