Question about tach wiring

I have an Air Guide tach and I can't get it to work. It has two wires coming out of it. Yellow and Brown. It came with the boat and was hooked up but I don't know if it ever worked. I don't see anywhere that you can set it for different pulses. Is it missing a part? I see where some of the older ones had a pulse box that came with them. Can anyone help. Thanks Mike

My air glide has the pulse settings right on the back of the tack.

Are you getting any reading at all? Or is the reading you are getting incorrect?

Hi Mike, Any chance you know the model number of the Airguide Tach? Some of them will have a small round sticker on the backside with a number on it. Even if not that type of sticker, Are there ANY stickers or markings on the back of the gauge ?
Also, what motor are you hooking into with the tach? Is it Magneto, or Battery / Coil ?
2 cycle or 4 ? How many cylinders? What year motor ?

I have bought, traded and sold many many Airguide Tach's over the past ten years. I have kept a copy of all the instructions, that were with any of the gauges I bought. Most that I've bought were New Old Stock in the original boxes. I think I can help you figure this out - but I need more info from you..... And/Or can you post a picture of the front and back of the gauge ?? that would help too!
