The engine relay panel for my '71 is garbage. Does anyone rebuild these or make something similar without all of the heater and window defogger stuff? I have removed all of the heater components from the car and stripped all of that wiring out of the harness. All I need is the power supply relay, fuel pump relay, and voltage regulator provision.

I don't see anything relay board related on Jeff's site


There are several threads here about refurbishing the relay board. Some require re-soldering of the through connections.

Thanks for the info on Jeff Bowlsby.

Do you have one bookmarked or can you think of someone who posted a thread like this? I do actually search for this stuff before I post I will probably try to build a new one from the posted diagrams and available info.

I would be willing to give it a go, if you cant find someone else. I have a vast electronics background

I can do a stock one for you. I will not be able to reproduce the thick tar but I can seal the bottom with a new product.

I just noticed today that the tar is falling off of my replay board. What kind of product would you recommend me using to reseal the bottom?

The tar was cracking/falling off my relay board also. I removed the tar by carefully chipping away at it really wasn't that tough to do. I cleaned the bottom of the board with alcohol and a brush. Visually inspected the solder joints, all looked good so I sprayed black " Dip It " on the bottom of the board. This is sold in many box stores like Home Depot. Originally it was a liquid that you dipped tool handles into to make a rubber/vinyl hand grip. They then added an aerosol version. I sprayed about 4-5 layers it does not build to a thickness of the original but it is waterproof and flexible. It has been working for 4 + years with no issues.
