Troubleshooting turn signals

[Bluesky]

Last winter I went through the turn signal system in my bus and made this nice document. I hope it can help others that may have similar issues. My bus is a 1955 Chevy, and the turn signal switch is a Grote 966-4. The flasher relay is Buss 550. This is probably the most basic type of turn signal system as the turn signals are separate from the brake lights.

Here is a diagram of the system.

Hey thanks for the documentation! Someone, somewhere, sometime, will need that. I'm not being sarcastic; we collect ALL the information we can around here.
