I have a Ryobi Mod D18-C drill that I have had for 20 years or so and the switch failed some time ago. So I bought a new cordless drill but I would like to get this one running again. I ordered a switch for the model above and got it here several days ago, but The switch is not exactly the same as the old one. I see the same number of holes for wires in the switch body but they are configured differently and I do not intuit which wire goes where. Is there a site that has instructions for such a project? I have looked and found nothing that I could interpret. But there are a dozen or so places happy to sell you another switch if you want one. I wonder if the Fastenal store has any info. They are just up Bay Rd from me. The last thing I used this drill for was trimming brass with a Lee trim outfit. ( shooting related)
