[QUOTE="PSG-1, post: 322818, member: 6937"] I ran a Teleflex tachometer off my Tigershark engine, and it worked correctly. I had to fiddle with the potentiometer adjustment on the back of the tach to get it dialed in to read correctly, but once I did that it worked fine. As per ABYC codes, most of the time, tach wire is going to be green. But the sure way to find out is to use a little 12V test light. Hook the negative lead to a negative wire, then, put the positive lead on the wire you believe is the tach wire. Start the engine and see if the light pulses. If so, this is the tach wire. If the light stays on with no pulsing, this would be an ignition wire. When testing like this, it's a good idea to use little 1 amp glass fuses rigged inline on the positive wire, in case you cause a short, you won't fry anything except a fuse. [/QUOTE]
