Hi all, 73 Matador new-to-me project. Driver's side turn signal blinks slowly, but the longer it's on the slower it gets until it doesn't blink any further. Passenger side is a bit better and seems to do a better job of blinking. Relay or maybe some sort of ground? Thanks, C

in a car that old its a good possibility that the ground is failing.. heres what i do.. i get a piece of wire about 25 feet long, attach one end to the negative battery cable and take the other end to the bulb socket to see if the new ground wire makes the lamp work correctly.

Sounds like a failing flasher , easy fix . Just make sure you replace the right one ( there are two) turn on signal light and you will feel which one it is .

The flashing speed is related to the amount of electrical current flowing through the flasher as it uses a heater and bimetallic switch. The more current the more heat the heater makes. All the connections must be solid for it to work properly. Bad connections are resistive and less current will flow. This includes the turn signal switch. They have a grease in them that eventually attracts enough dirt to gunk up and impede the electrical current. You may have to remove it and clean all that out. I had to do this on a friends Machine recently. -Steve- |

Buying a can of deoxit and going to town isn't a bad call at all honestly. I've definitely had some flaky connectors in my Eagle including the one at the steering column.

The other problem with the old bayonet base sockets is that the tension spring beneath the contact(s) is dead.

Conversely, I’ve added solder to the base connections on otherwise sound bulbs where it was worn concave. It saves an incandescent bulb, which are on their way to being no longer produced. Easy to do with a decent soldering iron and good ol’ lead/tin solder.
