Miata Project, Batteries intervene
The next project on the list was fixing the window in the Driver's Side door of the Miata. Cable Broke. But, my little battery project on the big boat intervened when I ended up with three nearly dead battery banks. Two of which, were brand spanking new.
The onboard Battery Charger had died.
The first charger I bought, fried right up. It was a 12 amp charger and I bought it on the assumption that since there is usually a week between uses of the boat, that I would not need a fast charger. That baby toasted. Discussions with the good folks at Guest revealed that their smart charger, sensed the need and tried to perform until it overheated and died. They were good enough to give me my money back and recommend a couple of companies who make chargers large enough for my large battery bank. After a bit of research, I decided on Charles Marine.
The little red headed boy is taking pics, so we get an interesting perspective.
These things are pricey, but shopping around never hurts and I almost ordered one from Defender who had the best online price, when I decided to give my local boatyard a shot at it. The reasoning being that with $30 in shipping charges from Defender, they might be competitive, plus I could have it now.
Charlie at Yacht Maintenance came through. Not only was he competitive, he flat out beat Defender's price and I had it the next day, with no shipping charges.
Once it was finally installed, I was a little nervous after I turned it on to see the ammmeter pegged at way past 50 amps. After my experience with the undersized Guest Charger, I crossed my fingers that the Charles Marine wouldn't fry, too. My largest bank is 450 amp hrs and 50 amps of charging is technically enough. But, the engine bank and the windlass battery were down too. The total demand on the charger was probably something more like 65 amps. After a little over 2 hrs, the ammeter fell back to just over 50 amps and I relaxed and went home. Next day I returned to find it still drawing 10 amps and the following day, it was up to float and only drawing 3 amps.
Next day, my new inverter arrived to replace the undersized toasted one and a few minutes aboard had that installed as well.
Now, where was I with that Miata???
