Voltmeter, Ammeter, Tachometer, Speedometer and Hour Meter Talk About and Info Thread

There's been alot of talk recently about these in different threads but the problem is that info gets lost so I thought I'd start a thread dedicated to them or any other on-board monitoring equipment you want to talk about! What good, what's bad, what's useful and what's not?! Feel free to jump in to post your comments, add your experiences, showcase products and ask questions!

@diddie made a comment in @MightyRaze"s thread so here is a link to @Nevadablue"s thread that @LAWN MOWER MUDDER contributed to by showing his analog tach and granting your wish! Lol

Now that I have everyone's attention I encourage you to post what you said/shown in other threads so we can make this a resource thread!

I'll start by quoting myself with relevant info:

After some testing last night I realized that an ammeter is pointless on this build because there isn't nor will there be enough draw on the system to make it worthwhile, I mean I haven't even seen it twitch and I know it works! I'll get more use out of the voltmeter to keep track of battery voltage because of the winch.

This I posted in @MightyRazes thread,  I'm hoping he'll add to this with his tach and a link to it.

I have 2 of the exact same ones (one in my G10 and a loose one), I find the RPMs lag and it's hard to read unless it's at a good angle but they're great for setting idle and max speed.

I got it off amazon.  Hope it works well enough.  Untested.

I am going to try this chicken chow-mien tach/hour meter.



It said 5 or more winds.  I went with 14.   

I have some things to add here Brian, but I want to actually test them before I post about them. They include Tach, ammeter/voltmeter and GPS.

I have tested the GPS a bit, driving around the neighborhood in my RTV and it works well as a speedometer like I hoped.
