I am looking for some turn signal help. I have tried the usual suspects but I'm a little confused about this one.
1977 C30 Automatic
Tested 12s volt on both sides of the glass fuse - Good
Tested 12 volts at the flasher (552 Round Style) - Good
Tested 12 volts up to the switch on the purple wire (on flat plug) - Good
New Turn signal switch installed because it was cracked at the turn lever.
When I turned on the 4 way flasher and all the park lights and turn markers flash, Dash indicators light up.
I do have Backup lights.
New Parts Installed. - Neutral Safety Switch, Turn Signal Switch
When I move the Turn lever for Left or Right signal the 12 volts at the purple wire drops to 0 Nothing Happens. When I put the turn lever back in the center neutral position 12 volts returns to the purple wire on the turn signal switch.
