How is the servo to be mounted: the throttle lever/arm on the left ( P1) side or the other way around? The fuel inlet has been prepared by the company on the same side as the throttle arm. And how to route the fuel lines? Vans instructions on installing the FAB explains under "VA-131Q-1 installation" that the box should be adapted ( cut away a part); the photo shows the mixture arm on the left side, I think. Could someone, who has been there, enlighten me please.

If you could provide a diagram of the shunts, switch, and ammeter, it would help (me at least). My suspicion is that this is where the problem may lie. Dennis Glaeser -------------------------------------------------- From: Kevin Jones Hello Folks, I have a problem that is very similar to the Aeroelectric Connection issue of the same subject from 2001. I've got a Vans -40,0+40 ammeter (load meter) connected to a 40mV shunt wired exactly (minus the fuselinks) as Figure Z-13 in the Connection. I also have a 10mV shunt wired to read the aux SD-8 alternator loads. The signal wires from the two shunts are controlled by a switch on the panel. Main is wired to show negative, aux is positive ammeter deflection. The following is my scenario: 1. Ground operation with engine off; power supplied to main alternator feed through a radio shack 13.8V 3A supply. 2. Ammeter power is on the E-Bus, with alternate feed switch off. 3. Power supply is providing ~3A and I measure 3.8mV across the shunt. Shunt voltage to ground is 13.08V. 4. Instrument reads ~3.5mV at the sense wire connections 5. Instrument power voltage is ~12.2 volts 6. Ammeter shows full-scale discharge (negative). If I turn power supply off, this doesn't change??? If I switch on the E-Bus alternate feed, the ammeter returns to zero. Instrument voltage increases to 12.6V. If I power the alternate alternator feed, ammeter shows slight positive deflection, but nothing near the 35% deflection expected. How robust are the Vans ammeters and should I invest in a new one or re-wire the system? Why would opening the E-Bus alternate path cause a change in ammeter reading? Many thanks.
