Wininae39 -- I'm just trying to go an easy route with this replacement. We just replaced the batteries with two AGMs and I don't want to complicate my life more with solar. We live in an area that has an RV dealer, but they refuse to work on Airstreams --"they are too complicated!" The closest AS dealer is a 4 hour drive.
BayouBiker -- I need to purchase the remote if I don't want to change out the DC board, which I think would be almost impossible because it is not arranged the same way the current DC board is. The wiring connections on the new board would require lengthening some of the AS wires. Something I'm not prepared to do. Also, like you, I think I would seldom use the remote.
Too tall -- That seems like a reasonable option, but will it fit in that narrow space? And the wire is so long, I would have to cut it and rewire the connector.
At this point, I'm thinking about returning the PD4655 and buying the same Parallax 7355 converter (bottom half). I know I will be sacrificing the 3 stage charging, but at least the install should be a lot easier! Thanks for everyones comments!
