Sticking starter swtich

[johnbuckley]

The contact in the starter switch sometimes seems to weld itself to the button on the motor. Any suggestions?

I dissassemble the switch and resurface the contact points. If the bronze plate has any cracks at the bolt hole, discard that part. Gar Williams

What Gar said above, also I had good results from bending the spring contact slightly "away" from the stud on the starter.

I've done the same thing as Sparky said. The spring seems to get weaker over time, and now and then needs to be bent back a little.

I've added a small section of rubber hose under the copper (I have a repro switch) contact spring in order to give it a more of a push upward when released.

Low voltage supply will cause this too. Make sure the battery, and grounds are up to snuff.

Had the same problem on my Dad's Coupe, we decided to get rid of the floor switch and wire in a button/solenoid........it was a huge improvement.

Also make sure the starter is in good shape & not drawing to much current.Also if starter,switch and wiring are up to snuff,no solenoid needed.

I did what Will N did and it works great.

Some of the cheapo repro starter switches have bronze or poor grade of copper for the contact arm. This will heat up and lose its springeness.

"This will heat up and lose its springiness." This will also happen if the starter is engaged for long periods trying to start a stubborn motor or one that needs service
