Great photos of your PD 4645 upgrade. This should go in TC University's electronic section. So far, I've been very happy with our Mag 4645 upgrade. The old, original 63XX had a ballast resistor, like for a car. Add a few wooly buggers or something that crawls and you have a ripe stage for a fire. Luckily, that never happened. The 63XX just stopped working. It's difficult to access the value of the PD upgrade since we added 200 watts of solar; all interior LED's and a new battery keeping everything up all the time no matter what our watt usage. Once we start using the heater and other more watt-hungry appliances we'll see how close to the edge we actually are. Another upgrade was an aluminum shroud behind the refer exterior grill allowing us to actually travel now with propane running the fridge. I still keep checking everything, but my faith in the upgrades grows daily.
