Steven Posted August 2, 2013 Report Share Posted August 2, 2013 I put a new Odyssey PC310 battery in my CTLS in March. It struggled to crank the engine fast enough and after about 3 weeks could no longer start the engine. The PC310 generates 310 peak amps. Fortunately the engine easily started using an auto jump starter (1800 peak amps). I flew the plane over to the dealer and they installed a new Super B lithium battery which delivers 450 peak amps. That worked for 3 months, albeit I thought the battery was struggling a bit to crank the engine fast enough. Then last Saturday, the very next day after a 2 hour flight, the battery could not start the engine, cranking it just a little bit. I fully charged the battery using its specially designed battery charger, but that didn't help. I also thoroughly cleaned the battery terminals, but to no avail. The jump starter can still start the engine, so the plane is heading back to the dealer in about 2 weeks. It's a 5 year old CTLS with about 360 hours engine time. What could the problem be ??? 1) Bad wiring ? 2) Corroded terminals ? 3) Bad starter motor (runs degraded and needs more amps to work) ? 4) Bad starter solenoid ? 5) Two consecutive bad batteries ? 6) Alternator is not adequately charging the battery ? Any other ideas or guesses as to the most likely cause ? Is there any harm in using the auto jump starter till the problem is resolved ? Link to comment Share on other sites More sharing options...
