I bit the bullet and took the Bambi to a local dealer. The OEM converter/charger wasn't charging and the converter side was only putting out about 8 or 9 volts (dim lights).
Since we were leaving for a big Disney camping trip, we bit an even bigger bullet and had an off the shelf 3stage charger installed on the spot. But it supposedly will take care if our new bluetop optima batteries and the Perko battery switch I installed (thanks Phoenix)
Wallet a bit lighter but springs maiden voyage was successful.
