Zamp solar alternative

rbp111 , which pin do ya protect, the + or -, if ya protect the + from the battery and the + from solar ya get reversed polarity and things like battery tenders won't work without an adapter. If ya want to use some kind of connector ya need to make sure polarity is correct across the connector, easy enough to do.

rewire the zamp connector, rewire the panel, use adapters, replace the zamp and wire a different connector, there are options that are cheaper than a pricey zamp suitcase. Then add a new sticker that says Not for use with Zamp!
