Re: Delco Remy Brushes Not on iboats
The old brushes did have some crimps just before the contact pads. I opened them up and pulled the leads out of them. I then cut the old brush leads close to the contact pads since I couldn't melt the old solder. It must have been silver solder or some other high-temp stuff that my iron wouldn't melt. It wasn't a problem though. I cleaned the old contact pads and the bit of the old leads that were still attached to the pads. I then tinned the new leads. Then I put the new leads in the crimps and closed them up. That helped to hold the lead ends on the contact pads. I had no trouble soldering the ground lead. However, I had a bit of trouble with the hot lead. The guy at the shop recommended making another crimp to use directly on the contact pad. I made one out of copper due to its high thermal conductivity. Not only did the crimp hold the lead end in place, but it also pulled heat around the contact pad and helped to distribute the solder nicely. It wasn't the most beautiful solder job ever, but I believe that it is structurally and electrically sound, which is the point, and the solder wasn't interfering with the armature. The first pic is the new vs. old brush. In the second pic, you can clearly see the crimps. The third pic shows both brushes soldered in. Thanks to all for the advice on this.
