john57717 Posted February 18, 2015 Report Share Posted February 18, 2015 I have a1990 holiday rambler alums lite. Pulled my battery for inside power and charged it. Put it back in and it almost welded itself to the wingnuts. It was hooked up correct. any ideas? Thank you Link to comment Share on other sites More sharing options...
Kirk W Posted February 18, 2015 Report Share Posted February 18, 2015 Welcome to the Escapee forums. We are happy to assist in any way possible. It sounds like either reversed polarity or a direct short of some kind. Am I correct to assume that you mean it arced in a big way when you connected the second lead to the post? Did you reconnect negative cable last? Did you leave it connected and if so, do things work now? I am thinking that you don't mean just a spark but some serious fireworks?

john57717 Posted February 18, 2015 Author Report Share Posted February 18, 2015 Lots of sparks. it is disconnected now. Link to comment Share on other sites More sharing options...
Kirk W Posted February 18, 2015 Report Share Posted February 18, 2015 And you are sure that you are not reversing the polarity? Have you checked things with a meter? I'll have to give this one some thought.... Good travelin !...............KirkFull-time 11+ years......

pjstough Posted February 18, 2015 Report Share Posted February 18, 2015 One possibility is that if the battery was dead before charging, it may have been connected backwards to the battery charger, and now the polarity of the battery is reversed.

Paul X2. That would be my guess. Unfortunately, reverse charging does irrevocable damage due to the composition of the plates. You can still use it with very limited capacity, but personally, I would not. Trade the core in and start over. Hopefully, none of your rigs electronics were damaged. I would pull the converter and give it a good look see before applying any additional power source to it. Link to comment Share on other sites More sharing options...

That is a possibility and if it is the case, a new battery is in order. Good travelin !...............KirkFull-time 11+ years......

oldjohnt Posted February 19, 2015 Report Share Posted February 19, 2015 In addition to that mentioned above, perhaps when the battery was removed a cable or one of the wires that gets connected to the batteries POS + post somehow got against frame ground. Put a voltmeter on the battery to check voltage and verify polarity and also use an ohm meter to look for shorts to frame ground via the trailers POS + battery cable terminal connection. Some electronic devices draw a small amount of current when first connected to a battery HOWEVER that creates a very low current small spark. If its not any other problem, I suspect a wire or cable that connects to your batteries + is getting a short to frame ground. You might also check for loads/devices/switches that were left on inside the trailer which would cause a spark when the battery is connected, albeit NOT a huge high current arc..
