      What is the difference it makes to run a 6 vs 9 volt? Could one or the other harm the ignition? I’d love to try something that will last awhile too.

       

      I don’t think so but except for my little test I’ve always used a 6 volt battery. Years ago I heard of people using 7.5 volt drill batteries. Remote controlled car batteries is another option I have heard of people using.

        What kind of run time did you get out of one of those batteries? I’m hoping I can get something decent out of it.

          That’s an interesting design. What kind of runtime did you get out of those batteries? What would you recommend as a first-time battery-ignition runner?

            When I’m at the lake, weather permitting, I’ll be out 2 to 4 hrs. a day. 2 years ago I brought a 1928 Speedster. I had one, 5 year old Power Sonic battery, and a new one. I decided to see how long the old one would last as I had the new one as back up. The old one lasted 6 days. When the black ones were 3 years old, after an hour running, the motor started missing. These batteries a relatively small. Little smaller than a hunting camera.

              Good to know. I will probably go with the ones you sent the photo of. For relatively small use, I assume that I can get away with one battery?

                Tubs:

                Checking for spark on these, I assume I need to have the battery connected too,  and just check spark normally?

                  One of the good batteries is adequate. When a battery is getting low a motor will miss occasionally. As time goes on the miss happens more often. You have quite a bit of time before the motor will barely run and then comes to a stop. You will need to have a batt. connected to check for spark.

                    as Tubs said, a battery must be connected to check for spark.  Make sure your plugs work before you check the spark unless you have a spark tester.  Rotate the flywheel until the points connect.  If there is no spark, try to hold the battery leads onto the battery to make sure that they make contact with the battery.  If you don’t get any spark after that, check that the battery lead wires are not broken inside, and if that is not the problem, you may have to redo the coil.

                      Tubs-

                      Will that battery you recommended work well for a ruddertwin?  I have been running it on a 9-volt for test runs as I did not have any other battery on hand.

                        That battery will be acceptable for any Super Elto and I suspect any pre. WW-II motor with a battery ignition, but it is just one of many options.
