 Posted: Sat Jan 09, 2010 9:08 am Post subject: Ammeter shunt physical location |
 |
|
All, architecturally, I'm putting my ammeter shunt between the battery and everything else. Physically, I'm not so sure. I'm considering putting it near the starter solenoid, as shown in the attached picture, or above that on the "tilted" part of the firewall.
Anyone have any suggestions or pictures of what you've done? I'm also going to use an ANL limiter next to the shunt, so it makes sense to me to put these both on the engine side of the firewall.
Thanks...

Rob,
I was just working on the connections to the shunt myself. Mine is located on the cabin side of the firewall for a couple of reasons but primarily because it required fewer penetrations of the firewall for the way I wanted to use the shunt. Also, it is a more protected location.
It has always surprised/annoyed me that these shunts don't come with some sort of cover. Does anyone have a suggestion for how to cover the shunt?
The question that you might first want to ask yourself is what do you want the shunt to indicate? The AFS wiring diagram shows it in-line with the alternator output which will indicate the total output of the alternator but nothing else (it will never show a negative indication). The Dynon diagrams gives three options of where it could be placed in the wiring diagram. The location depends on whether you want to see the load on the bus. It shows as negative amps when the alternator is not on-line (battery supplying all power, such as prior to engine start) and as positive amps of the amount of current the alternator is providing to charge the battery.
If you haven't already, you may want to give consideration to the connections from the battery to the bus with the placement of the shunt.
Again, if anyone has a good way to cover the shunt (pictures), it would be greatly appreciated and no doubt helpful to many.
Good luck,
Nick

Get a can of plasti-dip in your favorite color and brush on
|
a few coats. It also comes in a spray can, but the coating
will be paint-thick.

As you say, with engine monitors that have alarms, it's good

to have both charge and load current (without the
alternator) available. This places the shunt between the
buss and the battery. I plan on placing mine on the sub-panel.
