Testing Grid Lines - Bus Bar Terminal Repair

The rear defogger bus bar terminal can be attached by soldering using solder containing three percent silver and rosin flux paste.
1. Buff area to be repaired with fine steel wool. This removes the oxide coating formed during glass manufacture.
2. Apply the paste-type rosin flux in small quantities to the terminal and bus bar repair area using a brush.
3. The soldering iron tip should be coated with solder beforehand. Use only enough heat to melt the solder and only enough solder to ensure a complete repair.
4. Do not over heat the terminal when soldering it to the bus bar.
