Starter switch/box grounding strap location and type?


Recommended Posts

I've read some discussion here about the grounding of the starter switch/box and have seen several electrical diagrams that show the box being grounded. My 1920 is currently grounded to the horn mount via a wire running from the starter switch/box terminal labeled ground. 

 

Myers offers these ground straps based on the year in their catalog (with picture):

I'm thinking my horn mount ground is incorrect and an old work around... Does anyone know where these ground to? Transmission/bellhousing bolt maybe?

That strap ground the starter switch to the steering column, to steering box,  to chassis and then to engine. If you  have a good ground wire to the engine that should be sufficient. As the horn is bolted to the engine, that is supposed to work, but best to have a decent ground wire frame all electrical bits, back to the battery and engine. 

 

Grounding through multiple connections and especially through paint should be avoided.

 

An example of what not to do was demonstrated years ago by someone who had fully rested an old Indian. He could not get the lights to work properly because all parts were thoroughly painted. He then proceeded to remove that paint from all mounting surfaces when he could have run an earth wire back to the battery parallel to the feed wire on all electrical devices [ including the engine ].

Anyone have a picture showing the location, I haven't been able to find one yet.

 

The ground wire on mine looks to be a much later addition and I'd like to deep six it with the correct unit.

 

Thanks for the info Cutdown, very helpful!

I just took photos of mine before I realised my car is rh drive '23. Might help though but not easy to see where it is. Lh pic shows where it is bolted under the floor board by the steering column. The rh pic gives a wee idea of its shape near the steering box. It could be the same as the one in the middle of photo above.

Thanks for posting the photos of one installed. While I haven't had any running/charging issues so far, I will take a look at mine and see if I have a strap installed.
