Amp meter getting to much power....

[Nizodd]

Well i finally got a replacement amp meter and now i'm trying to figure out why the it is always getting power... as soon as i hook up the battery the meter goes all the way to the right... does anyone have an idea on what is wrong?

Sounds like the shunt may have gone open circuit.

shunt?

[Walter Moore]

The shunt is the low resistance resistor across which the amp meter measures a voltageto derermine the current in the charging circuit.

If you have an ohm meter, there should be very little (practically zero) resistance across the leads of the amp meter.

(Does anyone know if the shunt is internal or external on the Z Amp meters?)

I know it's external, also has a couple of fuses attached. From memory it's located , I can't remember without going out to the car, perhaps someone else can step in.
