Why do I ask? Because today I fried the shunt on my 30A ammeter. This shunt operates in line between the battery and starter. I've noticed lately that starting has been slower and I attributed it to lower battery capacity. Today I checked the voltage at 13.1V, then tried starting. I got three very slow turn-overs followed by a click, then nothing. It turns out the click was the shunt separating. I've got probably 100 starts on this system over the last year. I did a resistance check of the starter across the "big" wires and got only 0.3 ohms. Is it possible the starter is shorted? How can I tell if the starter is bad? Do I dare simply attach the battery to the starter directly to see if it works? I could also simply by-pass the shunt to see if it works, then I could use the start switch. I'm concerned, however, that if the starter is shorted I could blow the battery. Is that a possibility? Thanks, Guy Buchanan K-IV 1200 / 582-C / Warp / 100% done, thanks mostly to Bob Ducar. ________________________________ Message 2 _____________________________________ Time: 01:04:34 PM PST US From: NYTerminat@aol.com Subject: Re: RotaxEngines-List: Rotax 582 Start Current Guy, The wire to the starter motor should not go through the shunt, the load for everything else goes through the shunt.( ignition,lights,radios,flap motors,trim motors, etc.) I am surprised that you were able to get any starts at all without blowing the shunt. If you want more info on wiring, go to the aeroelectric.com website. Bob Spudis N701ZX/CH-701/912uls In a message dated 2/8/2007 2:06:19 P.M.
