KR> battery location
Battery installed on floor near the front door> Been -30's/-40s here for a week, New record at Edmonton International Airport -46c no/nil wind. I'm preheating my vehicle with a propane space heater...-40F same as -40c (-40 is where they both meet/merge)Feel like an Ice Pilot > New Reality Series YouTube Preview ICE PILOTS C-146's etc..WWII Haulers http://www.youtube.com/watch?v=BeAFBoo7tbA=related

#2 Welding sounds like the ticket. It sounds as though length (in KR terms) doesn't matter. I still think shorter is better so I will move it forward since I have the time. Thanks to all. - Original Message - From: "Mark Langford" n5...@hiwaay.net Well I found a place that says a reasonable current draw for a Sentra starter can be as much as 200 amps, so based on that, a 2 AWG wire would be better, and the added weight would be minimal over that short 5' distance.

But the distance from the front of the spar to the rear of the rear spar is only about 24" or so, and I don't see that making a huge difference in starting capacity. - I moved my battery around during the early flight staged, and testing, I went from behind the pass seat to firewall aft side, as Mark did. I now have a heavy forward Cof G, I need a min 70kg pilot to fly and I have a no problems with fuel with two in the plane. ( But I have wing tanks, with very little CofG change from full to empty.)

If you are sure your connections are good, and your cables are reasonable size, they ought to work, but if they are old and internally corroded, a new set of cables with very clean connections may do wonders. I forget exactly what my cables are, but I believe I used 4 AWG cable, which appears to be plenty for just about any kind of KR installation (see http://www.e-marine-inc.com/products/alternators/cables.html for more on that). I'm starting a Corvair with a Sentra starter and a 20 Ahr battery, and it works fine, even on 30F days like Saturday when I flew it just after dawn...

Maybe that's what I used. I'd check the leftover box, but it's out at the hangar. There's a little article on that at http://www.aeroelectric.com/articles/bat_cabl.html where Bob says #2 welding cable is the ticket...much more easily bent, and dirt cheap compared to aircraft cable...

Mine is in the firewall inside the engine compartment. In your case, moving it that far forward will effect your CofG. You will have to calculate this to ensure you stay with in limits.
