I have a 1945 2N. Doesn't get used much. I have taken it to several shows and a couple of parades. I try to run it a couple of times a year. This summer I had trouble starting it when hot. Did all the usually electric things without a lot of success. I could start it if I bypassed the resistor and ignition switch. Changed the ignition switch with no positive results. The battery was less than one year old. Yesterday I tried to start it to change the oil and do the pre winter maintenance. The battery was stone cold dead. Would not even begin to take a charge. debated letting it sit until next spring, but decided to replace the battery. When I removed the battery (purchased at Orschelns a midwest farm and home chain), I noticed in bold white letters on the battery "Replaced free if it fails in less than one year". Took it back to the store and exchanged it - no questions asked. Put the new battery in and it started right up. Battery was 11 months old, Sure am glad I did not wait until spring!
