Adding turn signals to my A. I need help!

[Bob Bidonde]

Neil, those wire connectors you use are notorious for poor electrical continuity. These are especially poor for use in a vibratory environment such as in a Model "A". You should be soldering all wire connections.
Also, you can avoid all of the issues with installing & troubleshooting turn signals by using the reproduction wire harness with integral signals including a Signal-Stat.
