There is just no power and I can't tell which fuse circuit they are on. They don't appear to have their own fuse and unfortunately I see no burned ones. Tried flashers etc and the brake lights still work as do the tail lights.
The switch in the steering column feels just fine. I know, a service manual is in the works. These things really are a challenge to work on.
Any pointers would be appreciated.

 

If you have no turn signals in either direction, the problem is either the switch or the power going to it. The CSM will have a wiring diagram that allows you to chase the circuit and find the problem.

 

I guess it would help if I knew what the CSM was. I have a signal light diagram in my 63 Olds manual but it has its own circuit.. Basically my question is simple.
What circuit in the fuse box are the signal lights on?

 

Sorry - Chassis Service Manual.

 

They feed off the STOP lamps fuse, thru the brakelight switch. Since you say the brake lights work, that tells me there's an issue at the turn signal switch itself.

First thing I'd check would be the connector at the bottom of the steering column. It may have come loose after 40 years. Crescent-shaped thing with several wires to it. That might save tearing down the steering column, which is not a fun job esp on a Tilt-Telescopic unit.

Someone else on here was searching for a Toro t/s switch a while back. Search the forums and you'll find the part #s.
