Re: 1966 c20
Hanke,
It sounds like the turn signal switch is just flat worn out, if it feels that
sloppy. Pick up another signal relay like the one that should be plugged
into your fuse block and see if that makes a difference. Inspect the complete
wire harness run under the truck for breaks or grounds. these trucks are
bad for grounds coming off the tail lights. You may end up running a separate
wire to a frame ground from the body of the tail lights.
The small gauge red wire you're looking at should run across the radiator
support to the voltage regulator on the left inner fender (on chebbies anyway)
or the horn relay, mounted under the wiper fluid tank at the left side of the
radiator, if I recall correctly. They both have 12 volts going to them.
Just thought about the floppy feel of the lever. The screw that holds the
turn signal lever to the switch assembly may just be loose. Pull you wheel
and look at it, tighten it up, replace the screw with the next larger sheetmetal screw. I had to do that with my '65 short stepper.
My signal/tail circuit is acting the same as yours, gotta do the same steps.
If the harness is mucked up, it isn't hard to rebuild/replace.
I picked up the switch assembly from LMC for small money. It was identical
to the installed unit when I compared them.
Sorry for the long wind. Sitting here watching Adult Swim on Spike with not
much better to do at the moment.
Pick up a set of carriage bolts before you pull the bed. Not all of them
will be coming out in one piece.
