My old SC500 Yamaha hare scrambler had a kill button on the handlebar. The cover fell off leaving an outer ring and a center pole. I used my wedding band to short it out and kill the engine, until I did it backwards one time. OW! 79 Barth Classic | |||

And I thought my hacksaw blade kill switch was primitive! It could be rude if I were imprudent enough to use it without gloves, too.  . 84 30T PeeThirty-Something, 502 powered | |||

OK, this am the batt read 12.07, charged at 10 amp for 7 hours, now get 12.87. Good enough? I'm thinking no. 79 Barth Classic | |||

Report back after sitting 12 hours disconnected. I would recommend using a hydrometer in battery evaluation. A conductance tester can tell you a lot. Some auto parts stores use them. However, before giving up on a battery, it needs to be desulfated and maybe equalized. I don't equalize unless the SG varies .015 or more. A long charge with a charger that will hold 14.7 volts or so until the SG stops rising can help, too (rather than dropping off as do so many modern chargers). An old-style (or cheapie) ferro-resonant charger will often do the job. . 84 30T PeeThirty-Something, 502 powered | |||

I am an advocate for battery tenders for this exact reason. You can mount them in your coach battery compartment(s), wire to the battery terminals with the ring terminal provided and just run an extension cord to the coach when it is sitting in your yard. Your batteries will be charged every time you go to use the coach. Just unplug and go. This is not an answer to resolving an electrical draw, but will keep your battery charged unless the draw is more than the charger output. Also, if the battery starts to fail this will NOT "fix" a battery in need of replacement. Besides, with the quality of todays batteries these help you actually get much longer life out of them! I use these on all my cycles and classic cars, as they are not used on a regular basis. If you are like me and have two banks of batteries, one on each side of the coach, they make a two bank charger and I just ran a 12' extension lead from the one compartment I mounted the charger in to the other side to the ring terminal end mounted on the battery bank. And yes, a single charger will charge a bank of two batteries. I still just have to run an extension cord to the coach anytime it is in the yard and both battery banks are charged at the same time and ready to go when I am. Please keep in mind, this set up is just to keep your batteries topped off while it is sitting and help get longivity out of them. This is not going to power your 12V in your coach while it is sitting, though it will recharge the batteries if you are in and out of the coach while it sits in your yard. Try it. You can find them on eBay. You'll wonder why you didn't do this a long time ago.... 9303 3855 33BS 1B Bruce & Kathleen 1993 33' Front Entrance Breakaway 230HP Cummins 5.9, Allison 6 speed, Spartan Chassis, Nicely Optioned | |||

Although a bigger financial commitment, you could replace your current charger or inverter/charger with the newer multi-stage chargers that do just what Bruce referred to, but are built in and doing their job when you plug in the RV AC cord. This is an upgrade that will likely pay itself back in increased battery life, safety and convenience.

I agree with the battery tender, simple solution for any vehicle that sets unused for any lenght of time. I just ordered one on eBay for $44.99 free UPS shipping. | |||

A bettery tender is a good way to keep a good battery good. However, even a trickle charge can allow sulfation to form. There are a few battery maintainers that recognize this and stop charging for a little while every so often and then give a strong charge before settling down to a float charge again. Yuasa is one company that sells a maintainer with that feature. . 84 30T PeeThirty-Something, 502 powered | |||

I agree about the battery tender keeping a good battery good. I have also just purchased a "MotoBattery" charger off eBay, as they are a new version of the Battery Tender that have more functions, which i believe and hope will do what Bill H refers to above. If it works as advertised, I may be slowly changing all of my chargers to theirs.... Oh yea, one other thing. These chargers do NOT like lightening. Trust me, if they are close to a strike they will go kaput. Everyone of mine got smoked on a lightening hit. Not sure if the strike hit my building or just close by it, but I lost all kinds of electroic stuff both in my building and my house. Funny how those surges will travel.......... 9303 3855 33BS 1B Bruce & Kathleen 1993 33' Front Entrance Breakaway 230HP Cummins 5.9, Allison 6 speed, Spartan Chassis, Nicely Optioned | |||
