I have the hall effect amp sensor. At idle it is reading -1 amps, but if I turn on my landing lights it reads 6 amps. I don't think that it was setup for my engine/alternator.

After shutting down the engine it reads -7 amps. The a2d is reading 1676, so I set the 0 amp value to this. the other value is for 35 amps and is 2327. I have a 60 amp alt. Is this the correct value and did I set the 0 amp value correctly?

I also have a GNS430 hooked up through arinc as per the manual. The 430 give me the following error when it powers up "Not Receiving input data on 232 channel #1". What does this mean. I am guessing that I need to change the setting on the 430 or the EFIS.

I have alt. information to the 430 via gray code encoder.
