one lazy turn signal light

[cherokeechief79]

one side in the rear of my 67 wagon is lazy.
its much slower than the other side.
i havent done anything at all with it yet but i was thinking of pulling the bulb and grounding a test light somewhere else to see if the test light goes ant faster.
does this seem like a good start?

Higher circuit resistance on the rapid blinking side. Check for corroded
connections or faulty wire. The issue
could be the contact in the turn
signal switch itself.

we just changed the whole turn signal switch for another issue.
it was slow both before and after.
ill look at it this weekend.
thanks

I'd start with the grounds as well.

thats why i thought grounding the test light good and probing the hot lead in the socket will tell me if its a bad ground
