Push button star

[Scooter90]

Im consider replacing the starter push rod on my B with a push button or key with a solenoid. How would I go about connecting the solenoid wire to the lug of the starter?

Starter has to have the lug replaced with a bolt out of it so you can use a nut to hold the cable. My C has that

Sounds simple enough , Ill give it a shot, Thanks!

You understand this is not a "bolt up" thing? Heavy soldering is required and must be done without damaging the field coils or insulation. The current lug the switch contacts is soldered to the field winding leads inside the starter. It has to be unsoldered. Then the new threaded stud has to be soldered to the leads. Use care not to damage the insulation where the stud goes through the starter case.

Easy?? Not really. I'm always up for a challenge, so if it was mine, I'd try this first. Get yourself a piece of 1" wide x 1/8" thick flat strap steel about 3 or 4 inches long. Drill a hole in one end to accept your battery cable connection. Drill a much smaller hole in the other end, probably close to 1/4". Find a self threading screw and drill a hold right in the middle of your contact post. Drilling a hole smaller than the self threading screw naturally. Connect the flat strap of steel to the starter post. Now, the strap would have to be supported some other way than the screw and this would require rubber insulator of some sort. The screw would have to be short and need no point on it, so grind that off. Wild idea, but I think I could make it work.

SURE that will work, I've done it a number of times, drilled a small hole in the center of the copper pad, then tapped it 10-32, then attached a cable with a small eyelet on the end.

Connect the other end to your new starter solenoid.

We're not "reinventing the wheel" here, the HD starter pictured below has a similar setup from the factory, where a small screw at each end is used to attach the "strap" connecting the solenoid to the starter.

The soldering is not something I have any screw. How far do you think I could safely drill into the stud?

As long as the hole is centered and in line with the centerline of the copper stud drilling 5/15" to 3/8" deep should be no problem.
