Converter will not charge batteries
Hello, I need some advice. I purchased an old TC and on my first trip I realised the batteries were not charging when hooked up to shore power. My previous TC's converter always hummed when it was plugged to shore power, however, this one did not. I checked the connections at the converter and found the converter output was zero. I then replaced it with a Progressive Dynamic 35Amp converter. Once plugged into shore power I saw all the light blinking and check the battery connection to the converter and it showed the voltage from the battery. I then checked the output of converter and it showed 14.4 volts. Good I thought. Then after my next trip I realised again the converter was not charging the batteries. I checked on this blog and someone suggested there must be a blown fuse between the batteries and the converter. I then found the fuse and it appeared good. No change though, the converter still will not charge the batteries. I then did the following. With the battery disconnect the 12volt system doesn'twork. I used my voltmeter and checked the connectivity across the neg and positive of the battery connection on the converter and the resistance is zero. I also checked across the neg and positive of the converter and it too has a resistance of zero. I am no electrician but the resistance across the Positive and Negative terminal on the battery side of the converter and between the Positive and Negative side of the converter should not be zero but should be 1. I am at a loss as to what the problem is...any suggestions?
