Tach/Volt/Hour Meter....and maybe clock!
01/26/16 at 07:00:21

Trailtech has a new line of meters with the display now having an internal light.

One option is a tach/hour/voltage:

The manual seems to indicate that it also has a clock function.

This might be a great way for Savage riders to solve the problem of not knowing the time, what their rpm is, or when their battery is discharged. My big problem with any of these small gauges from TrailTech is that the internal battery is not replaceable, and the expected life is 5 years. (Their is a comment that the gauge will continue to operate with the key switch after the internal battery is dead....so maybe it still will be useful).

Somebody buy one of these and give us a user review!

If anyone get's one of their tachs to work reliably and give a decent functional reading let me know. I have worked with a Vapor unit and chased all the talks on different offroad forums that use them as well as calling them directly and I have yet to get a decent signal pickup that provides a reliable output.

I would love to have my Vapor's have a decent out put on rpm

Yep....I had the same problem with my Vapor unit. It worked OK most of the time and the rpm displayed was believable - but during the acceleration through the gears it would get a spike that exceeded what the engine was actually going. The spike would trigger the shift and warning lights even though I was not at that high of rpm. I tried several different values of resistors.....and finally I just used the sensor wire wrapped around the spark plug lead and had better results.

I posted a thread about this a long time ago...and the resistor I found seemed to work at first.....but later on I just used the wrap around the spark plug wire I believe.

As that thread says in multiple places, use a 600K resistor. You can build the equivalent with 2 1meg in parallel and than a 100K in series.
My vapor seems to work just fine with that configuration. Then again, I don't stare at my tach when I'm riding.

That resistor value came from Youzguyz - he was one of the first to install the Trailtech Vapor.....and I suspect that Trailtech provided it to him.

That is correct. I got the info from Trail Tech when I was having problems. However, my problem was that they had the power and tach jacks labeled backwards on my unit. Drove us crazy trying to figure out what was wrong.

The Resistor Tach Lead http://www.trailtech.net/7000-1004 has a 600K ohm resistor in it.
