Y'all know I redesigned my tailgate wiring. If you don't, click here for details.

Yesterday I was at U-Wrench-It, and they were having a half-price sale. They had just gotten in an '85 245GL and among other things, it had a virtually brand-new set of tailgate struts. The ones on my '85 were getting weak, so I grabbed 'em. Please note that the struts were not OEM - this becomes important later on.

Later at night, I noticed my tailgate wiper only worked very slowly. I also noted that switching on the wiper caused the plate lights to come on. How odd.

Today, I went to check if my rewire failed somehow, and found a bad crimp - so I fixed it. I went and rechecked the functions (with the tailgate open) and all was well. Then I closed the 'gate, and BANG! same problems.

To make an already too long story a bit shorter, this is the moral. Volvo OEM struts carry a ground path regardless of position. These particular aftermarket struts only make a ground in the fully extended position. That's why everything worked when the 'gate was open!

I added a heavy ground wire from the body to the 'gate, and all is better now. Just consider yourself warned - don't make stupid assumptions. I never considered that the tailgate struts might have had something to do with the problems, and wasted an hour troubleshooting. Adding the ground wire took 2 minutes.

So I win today's moron prize.

Actually, There is a black ground wire inside of each hinges that you can't see that provides the ground. The struts coincidentally provide a ground.

Only a moron would know this :) That's because when I replaced my tailgate wiring, I did it by removing the hinges. When I saw the broken wires, I thought, "how typical of Volvo that they would put safety straps in the hinges in case they break so the hinge doesn't come apart." Well, since I never saw a hinge come apart, I thought, "heck, I don't need these dang straps," and proceeded to cut them off.

Only after some similarly wierd tailgate occurrences did someone point out that these hinge wires provide a ground path, did I realize what I had done.

D@*&!!!

I hate being second moron.

I don't think a moron would have figured out the problem!

This is good info to remember, because I'm not the type to pay $30 per strut for those (or is that the aftermarket price?)!
