I'm putting my hood mounted turn indicators on my '69 Cuda and notice that they no longer get their ground connection through the sheet metal like they did before I restored the car. These indicators just have a single signal wire that runs through the hood channels back to the firewall near the master cylinder, where they connect to the wire harness. Apparently there was originally enough of a ground connection through the original hood/hood hinges, etc. I was meticulous in the restoration, and I'm not really surprised that I lost this ground connection, because I've got a lot of paint on those parts that were probably barely covered when new.
I'm not sure if I'm going to run a separate ground wire from these indicators to the firewall. I really don't want an extra ground wire service loop there to deal with.
Has anyone experienced this before? Appreciate all the help!
