wrote: The original OEM battery in my former Ford F-250 lasted for a full eight years but when today's batteries go bad there's often very little warning. I remember the day it died. When I first started the truck in the morning I sorta sensed that it didn't turn over as quickly as it normally did but the difference was minimal. I realized it was probably going bad so I headed for AutoZone to get a replacement. I intended to drive home, swap the batteries (didn't have any tools with me) and return with the old one for the core charge. Got into the truck in the AutoZone parking lot, went to start it and it didn't even grunt. Dead. Did you go back in and borrow a socket wrench. They brag about having loaner tools. My wife would have had them install the battery but that may just be a girl thing. ;-) I have swapped out several batteries in the Walmart parking lot. If I know I have a shaky one (like having to jump the car to get it going) I go straight to WM with the tools I need and take the dead soldier in with me. No muss no fuss. You can usually do the whole thing at the auto service desk with a side trip to the battery rack. Since the price is usually about the same I get the biggest battery that will fit in the hole regardless of what was there before. Sometime a Group 24 is even cheaper than the smaller one the OEM used and they usually fit. |

Ahh, you put Stabil in your generator's tank and the gas was good enough to start up and run your generator and therefore "So much for the stories that gas goes bad in a month or two." Gotta love that scientific methodology. http://funkyimg.com/i/2Le5c.jpg Universal truth from a single observation? Just an additional data point from the time the generator sat for five years unused with gas in it. (again, used some Stabil). After all that time it ran, although it took extra pulls for it to fire up. Once running, it burned up the five year old gas with no problems. I am in the habit of adding Stabil to the gas storage jug immediately after I fill it with fresh gas. In that way the generator always has treated gas and it has always fired up and run fine after long periods of sitting (i.e. 5 years). Just my experience and only with the little Honda generator. Works for me. Doing the same now with the gas I use in the little scooter, based on the luck I've had with the generator. The only difference is that the scooter uses high test (93 octane) gas. When it's time to put the motorcycle away for the winter, I'll do the same for it. In fact, the owner's manual for the Suzuki specifically says to fill the tank with fresh gas, add an appropriate amount of fuel stabilizer (the manual recommends Stabil), run the motorcycle for a while to distribute the treated gas throughout the fuel system including the fuel injectors before permanently storing the motorcycle. Are you up in Connecticut now or down south with us racists? Why put the bike up for the winter. There's usually a bunch of great riding days in the winter, at least around here. I just keep it ready to go all the time. I am still in Massachusetts, not too far from the beginning of Cape Cod. I am not a big fan of cold weather riding. I bought the motorcycle more as an impulse buy anyway. Might keep it, might not. We'll see. Actually, I enjoy riding the little scooter but it's not all that comfortable for longer rides. I keep kicking around the scooter idea. I'd get one of these. Very comfortable for a tall guy. There is also an extension for the windscreen. With a 650cc engine, the thing will scoot over 100mph and is fine on the interstate. https://www.cycletrader.com/listing/...ABS-5004031071 The inexpensive little scooter I bought is nothing like a Silverwing. Only 150 cc and has a top speed of about 60-65 mph on a good day. Still, it's fun to tool around with and make runs to the convenience store. It's not comfortable enough to go much further. I bought a color coordinated seat cushion for the seat that helps. I've about trashed the scooter idea anyway. Scooters seem like they'd be much more convenient than the motorcycle. But, I'd still have to put on long pants, a jacket, a helmet, and gloves, so the convenience really wouldn't exist. The thing I like about the little 150 cc I have is that it is super lightweight compared to a motorcycle. It's nimble, easy to maneuver under power or just pushing. It has a turning radius that is about half that of the Suzuki. The Suzuki CT-50 weighs 696 lbs wet. The scooter is just over 200 lbs. I noticed that the Honda Silver Wing is about 550 lbs wet. To me, although it looks like a scooter, it's weight defeats one of the main advantages of one. Each are made for different things. Oh yeah. The Silverwing is more a 'touring' scooter, as opposed to a 'run around town' scooter. I'd never checked the weight. Didn't realize it weighed that much. I've not ridden one, but when sitting and rocking it I thought it was pretty light. A whole lot of the weight is down low, so maybe that's why it felt nimble, as opposed to the Guzzi. |

One thing that surprised me about the Suzuki C-50 was that it's wheelbase (65.2 inches) is actually longer than the Harley Ultra Classics that I had at 63.5 inches. The C-50 is considered a "mid-sized" bike while the Ultra Classic is "full sized" or "large" but I think it's more to do with the engine sizes. My brother has a 2008 Harley Road King which is basically the same frame as the Ultra Classic. Sitting side by side, they appear to be about the same size but the seat on the Suzuki is noticeably (by a few inches) lower. With a smaller engine and lower seating, the center of gravity is significantly lower, something I like. I had a couple of Harley Softails also but I can't remember what the CG was like on them compared to the Suzuki. BTW, one other thing I've noticed (and something I have to be careful about) is that the scooter feels and handles very differently than a motorcycle. Took me a little time to get used to it. I have to think about it a bit when I alternate riding the scooter and the motorcycle. For some reason the motorcycle feels more natural to me. |

Those suckers were about 150 lbs each and hauling the old ones out of the engine room, then loading the new ones on the boat, down the hatch and into the engine room by myself wasn't a fun job. I had to replace them because the big, 3 output ferro-resonant type charger that came with the boat "cooked" the batteries over the course of about six months when I left the Navigator in Florida when we returned to MA for the summer. I hired a guy to look after the boat while we were gone (he scraped the bottom every month) but he never thought to check the water in the batteries. Not his fault though because I didn't think of it either. The newer, high capacity, switching power supply "smart chargers" with multiple outputs were just becoming popular and available at the time and I replaced the original charger with one of them when I replaced the batteries. Wasn't cheap, but neither were the batteries. Never had an issue after that and it didn't boil off the battery water like the original charger did. === I've replaced all of our 8D batteries with 2 group 31 AGMs in parallel. They have more cold cranking amps than a single 8D. I'm getting much better life out of them, with less maintenance, and much easier replacement effort. The physical footprint is slightly different but not radically. |

You can usually do the whole thing at the auto service desk with a side trip to the battery rack. Since the price is usually about the same I get the biggest battery that will fit in the hole regardless of what was there before. Sometime a Group 24 is even cheaper than the smaller one the OEM used and they usually fit. Yeah, AutoZone was kind enough to lend me some wrenches. It was still quite a project in the parking lot though. The engine compartment on the Superduty series Fords is pretty high and balancing yourself on the skinny front bumper while hefting the old battery out and the new one in was a bitch. The battery and it's replacement was a big son of a gun because the truck had the plow package which included a higher output alternator and a big ass battery. Still not anything like changing the three 8D batteries in the Navigator. Those suckers were about 150 lbs each and hauling the old ones out of the engine room, then loading the new ones on the boat, down the hatch and into the engine room by myself wasn't a fun job. I had to replace them because the big, 3 output ferro-resonant type charger that came with the boat "cooked" the batteries over the course of about six months when I left the Navigator in Florida when we returned to MA for the summer. I hired a guy to look after the boat while we were gone (he scraped the bottom every month) but he never thought to check the water in the batteries. Not his fault though because I didn't think of it either. The newer, high capacity, switching power supply "smart chargers" with multiple outputs were just becoming popular and available at the time and I replaced the original charger with one of them when I replaced the batteries. Wasn't cheap, but neither were the batteries. Never had an issue after that and it didn't boil off the battery water like the original charger did. === I've replaced all of our 8D batteries with 2 group 31 AGMs in parallel. They have more cold cranking amps than a single 8D. I'm getting much better life out of them, with less maintenance, and much easier replacement effort. The physical footprint is slightly different but not radically. I've noticed that AGM's have become very popular. Do they require a special charger? === They are rugged, have a higher charge acceptance rate and high cold cranking power compared to conventional lead acid batteries because of their lower internal resistance. Ideally they should be charged with a somewhat lower float voltage to prevent over charging. Most modern chargers have an AGM mode setting. That said, I have not changed the voltage regulators on my alternators, and my port side charger does not yet have an AGM setting although I'm planning to replace it with a newer unit. Now that you mention it I think the new, "smart charger" I installed in the Navigator had settings for either lead acid or AGM batteries. I replaced the batteries with 8D lead acid. This was many years ago now but I guess AGM type batteries must have been available then also. The challenge at the time was finding a "smart", 3 stage charger with three independent outputs and at a high enough current capacity. Smart chargers had been around for a while but not many with the ratings I needed. I forget where I got it. The three battery configuration was one for each engine and one for the genset but with the battery switches, you could direct battery power to any or all if needed. All I remember is those damn batteries were heavy suckers. |
