The Converter in my Mirada appears to be an upgraded version of the original Magnatek 6345.
The 7345RU isn’t one of the 3 stage converters that are available, but is certainly better than the original 6345.
In my Toyota, I had the original 6345 and upgraded it to a three stage converter. These are very nice as they adjust the output voltage to accommodate what the condition of the battery is. The original converters charging circuit was very simple. If the battery was deeply discharged, it could take a day or two to charge it. If the battery was fully charged, it could actually boil the battery over a period of a month or so and destroy the battery.
Original Magnatek 6345 looks like this:
This is the upgraded electronic Parallax 7345 installed in my Mirada
If I had the original 6345, I would upgrade it to three stage, and probably install a 55 amp kit
