Is your key on the column?
Sometimes the rod length down to the actual switch needs adjusting.

I have a single test lead with an NO push button (Normally off) in the middle.
Works well for jumping around a switch to test things.


The original - rebuilt - starter on my Buick engine started running slow after five years or so.
I thought it was the battery going south and replaced it.
Starter ran the same.

Replaced the starter with another HD model although this time around, an American rebuild.
Engine spins over on the starter like a champ.

Along those lines, if you have a good HD starter core, it may pay to have the local starter/alternator/generator guy rebuild it for you.
Better components most times and for sure, pride of workmanship.
