Happy New Year Everyone,

I am trying to do a bit of a refresh on my 1971, D-Jet stock car, (new vacuum hoses, valve adjustment, etc.) and I would like to pull out my AAR valve and inspect it closely (or replace with a known good one I have) but I am fearful on how to disconnect the AAR wire to the white wire. Its encased in what looks to be stock plastic rectangular wire cover, but figured I would ask for advice before I do any damage. Thanks in advance.

Best,
Reg

That's a common in-line spade connector. Don't pull on the wire itself, but get a long nose pliers and pull on the metal part of the spade connector that is just inside. You can separate it from either side.

Here's a picture of a 3-way, but same idea. Carefully pull on the crimped part.Attached Image

Oddly enough, I pulled my AAR this morning, that connector is a standard flat blade brass connector in the german plastic sleeve. Give it a shot of WD or Kroil and pull, it should come right apart. If you want to test the valve, put it on a bench and hook 12 volts to it. You should see the valve rotate and close in a few minutes. That will tell you if it's working. If it's not, Ian Karr has a great video that shows how to take it apart and repair it, if the heating coil is still intact.
Now I need to research how to check the Thermotime sending unit to find out if it's still good.

Just a standard space connector under the plastic housing.

Make sure that wire is well insulated. It supplies full time 12v sourced from the fuel pump fuse. A short to ground will kill power to your fuel pump and/or melt wiring depending on the size fuse you have installed on the relay board.

Curious, think an issue there would most likely always 'cause a popped fuse or could it be an intermittent thing as well?

I'm probably not understanding something about this connector, but just got to replacing my AAR which has this connector housing, I've disconnected it, but I'm looking for suggestions on how to make sure you line up the spade connectors (female from the AAR and male in the housing) so that when putting it back together they are securely snapped together?
