I've always suggested it's a good idea to carry a pair of clip leads in the Model A. They are easy to make your own if you just find some good quality clips. The local surplus store had a box full of quality clips where the wire could be screwed on or soldered on, and the cost was 25 cents each.
Here is a lesser quality clip where the wire can only be soldered on, but this would still work well for the job. You sure don't want to buy it though due to the cost. The price is so out of sight I thought it has to be for a box of 100. I emailed the seller to be sure, and the price is for ONE clip.
Yes, there are people out there waiting to clip you.
