How to wire Battery Charger

[dan313]

I currently have a Guest Pro Charger that has stopped working. I bought a Pro Mariner 1215p charger. On the Guest charger there are 4 leads. 2 pos and 2 neg. On the Pro Mariner 3 pos and 1 neg.
My question is what do I do with the 2nd neg wire. Can both wires get put on one terminal. Or do I just keep it disconnected.

I seem to recall that there was/is still two ground connections on the ProNautic chargers. I believe there is reference to this in the installation manual. Did you read through that manual?

Yes I did. And there are two. The light bulb just went off. I now know what to do with them. The Guess charger has the grounds on the terminals. That is where I was getting confused. Where the Pro Mariner has one on the charger and one on the terminal.
Thanks
