Quality instrument at a good price.
This is a good quality instrument. However Iâ€™m giving it three stars because it is not made by Michell but rather made by VDO and relabeled, they use a cheap sticker on the face to cover the VDO. On mine the sticker was off and loose in the housing. It also is set back so deeply into the housing that it makes seeing the instrument from an angle difficult. I was disappointed. I think I will save up and install the EI volt/Amp gauge.
Would not fit without extensive panel modifications.
These Mitchell ammeters have their own internal shunt.
Ammeters only measure amps and so can be connected to 12 or 24 volts.
Yes, this part is FAA PMA approved.
No as it has an internal shunt you do not need a sender.
Yes, this has an internal 12v light bulb.
Per the manufacturer you will have a connection for power and ground, the sender and lighting.
The ammeter is FAA PMA approved for use in certified aircraft. It does not have an AML with approved models. It is at the discretion of the A&P installer as to whether the installation is legal.
The voltage also is in regard to the lighting in the unit, but this is an incandescent bulb and would be hooked up to the lighting bus in your aircraft.
