45 amp converter in a winnebego

[BillR38701]

I had to replace my 45 amp converter that charges my coach batteries. The problem I am having is that my old converter had 3 hole receptacle on the dc side, the new one has only two. The old one has a ground, negative, and positive. The new one has only a negative and positive. What do I do with the extra cable?

would i leave the ground loose with tape on it?

Bill, if the box that the converter is in is plastic then a equipment ground is not needed and the bare ground wire can just be left unattached. If however the box is metal, there should be a ground lug on the outside of it somewhere that the ground wire will attach to.

This summer I had to replace my Todd Engineering 55amp converter with a PD9160. The old converter had the three connections for positive, negative and ground all together. The PD9160 was quite different in that the positive and negative were on one side of the converter but the ground was on the opposite side. Check and see if your new converter is similar.
