When we left Wednesday night for last weekends trip, I started the coach and it kicked into high idle. The little Freightliner screen showed low voltage. The gauge read just below 13 volts. Our trip was only about an hour and a half away and one I did not want to miss. I took a gamble that maybe the batteries were a tad low and that they would come back up under way so went for it. The gauge stayed at about 13 volts or a little under and about half way there, the check engine light came on. Once there, we checked the batteries with a load test and they were fine. They are less than two months old so I was hoping they weren't the problem. We checked the alternator while it was idling and it read between 12.9 and 13.3 volts. I was told it should be putting out 14 volts. We decided to go for it Sunday afternoon and headed home. Not knowing if it would help or not we ran the generator most of the way home. No check eng light this time but the gauge still read just below 13v. The cables are all nice and clean. Am I correct in thinking it is the alternator or maybe the regulator? Thanks, BillyRe: Water pumpI pulled the pump and tested it and it is indeed shot. Not only was in only working intermittingly, it looks like it overheated and the fuse holder just before the pump got very hot/distorted. I am surprised it did not blow the fuse. The pump is a Shurflo 5900-0201 5.7 . I was never pleased with how much noise it made even when it was new. I don't believe this pump is even made anymore and not sure if I wouldn't go with another brand anyway. Would anyone have a recommendation on a suitable/direct replacement? I read that Aquatec pumps are good.Re: Water pumpThanks for the response. Not looking forward to replacing it again. It wasn't easy when I did it 6 years ago!Water pumpGood morning, I have a question about the fresh water pump in our coach. I haven't posted in a while so I hope that I am asking in the correct place. I did a quick search but did not see a problem like this. The coach, '05 Mandalay, has only been out a few times this summer. I noticed the water pump to be a little louder than I think it should be. Over the weekend while camping, I went to use the kitchen sink and no water came out, no pump noise, nothing. Checked the bathroom sink and nothing there either. I went over to the panel, turned the switch off, waited a few moments, turned it back on and the pump worked. This happened a couple more times before we made it home last night. The pump was replaced when it was a couple years old. Any suggestions on what to do would be appreciated. I'm thinking it is time for a new pump. Billy
