I purchased a new pulse generator with my Dolphin gauges and there are 2 white wires, one goes to the speedo and I assume the other is 12v key on power? there was no documentation with the sensor.

I put this in the wrong forum, sorry.

thanks

 

I would probably contact the company and see if they can help.

If I had to guess though, I would think that there'd need to be some sort of power going into the sensor in order for it to generate a pulse. Think like a momentary push button, it only sends power through when the circuit is closed. As soon as it opens power is cut off. I would think a pulse generator would work the same sort of way.

Again, just a guess.
