Rear defogger not working

Half way should be around 6V. The closer you get to the ground from the feed the lower the voltage.

Hopefully I didn't cock that up, it's been a while since I've had to check one. They used to make repair kits for them.

It's been a while since I checked this but I believe all the lines had 6v at the halfway point. Plus I inserted an ammeter between the grid and ground and I believe it was showing 0.5 amps.

Has anyone replaced the rear windshield? How much was it?
