I'm wondering if anyone has or is experiencing amperage readout "float" with the Dynon 120. 2008 Flight Design aircraft (CTLS) with Rotax engine shows constantly variable amperage readout on Dynon 120. The amp meter appears to be a "random number generator". It constantly shows first high positive amp readings, then goes to negative readings and then back to positive. Operation of equipment, landing lights, etc., don't appear to affect this "float". The voltage meter reads constant +13.4 to +13.6 and appears to be OK and the charging system appears to be charging battery with no apparent loss of charge over time. Connections have been checked at voltage regulator. Fuse to Dynon ammeter checked and a new fuse installed. Any thoughts? Thanks.
