Dale;
The accessory voltage controller is the biggest waste of $130 I have ever experienced. I bought it believing there would be either multiple outputs which could be set at different voltages and addressed by an accessory number, or multiple program addresses which could be adjusted and stored for particular accessories. HA HA! The thing is nothing but a transformer with a single adjustable output. Sure you can fine tune your accessory voltage provided that every accessory on the circuit works best at the same voltage. If not, you have to reset every time you use any accessory, keeping in mind that all other accessories on the circuit will also be set to that voltage. I created an accessory bus powered at 18 volts, and put a rheostat between the bus and each accessory. Each rheostat is set to the best voltage for its own accessory.
Much better control than the AVC.
