Volts dropped

I would also charge the battery before the next flight..... just in case you need its full capacity !

Just curious, do you have a backup power system at all? Seems you are entirely dependent upon one master switch, one battery, one charging system to keep you in the air? Certainly your thought on a back up generator coupled to an emergency power buss is a good one and a must do, not an option. I really think you were very lucky to stay in the air, you might think about writing a thank you letter to Odyssey, if that had been a Concord or Gil normal aviation battery...

Amen to that!!!

It is very possible that your alternator is either not putting out power due to a bad voltage regulator or a loose belt or a number of other reasons. If you have a 12V power outlet, get a volt meter and see what it reads when the engine is running to verify the voltage.

There are two RV 10 based at S40.... if you come our way again please stop in and send a message. If you have a issue with your plane we would love to help in future.

Thanks for advice all. I have been at it tonight and am taking the alternator in to a shop tomorrow. The alternator is not showing a charge but hooked up to a meter and run with a drill it puts out better than 13. I have an earth x batter (was confused with an earlier plane battery) and I run with two, plus a back up battery behind the panel for instruments. It has been tested to run 45 min. With the additional Earth X battery, so from that regard i felt like enough safety has been built into the system. I am now thinking very seriously of an addl. alternator now.

Thanks for the invite, Will do! I love your little airport, plus lunch at the Red barn.

We have now confirmed the problem is the alternator. Spoke w/Dale at Vans this morning and it is arriving on my doorstep in the morning. I am going to look into a back up alternator. Thanks for all the great input.
