I have an electrical problem in my QV. Perhaps someone with troubleshooting the electrical circuits can help. The problem is the refueling door or the engine bonnet solenoid is blowing fuse #1 when the button is pushed. The other function this fuse is used for are the electric motors for the high/low beam which works fine. It looks from the schematic that the refueling door solenoid and the engine bay bonnet solenoid share connector C1. Can anyone tell me how to identify C1 under the LH side of the dash? Or does anyone have any ideas how to hunt this problem down. Thanks Bruce
The problem is a moving target. I just went down stairs to the garage and pushed the engine bonnet switch and it opened. I did it several times and it worked every time. Why beats me! I then took a piece of wire and shorted the connections to the fuel door solenoid. The fuse didn't blow but the solenoid didn't actuate either. So now I thoroughly confused on what the problem is. IDEAS?
I think my mystery is solved. I finally figured out how to pull the solenoid. When I got it out of the car I found the wires connecting to the solenoid frayed and shorting. I am not sure if this is the fix but I have to replace it before continuing on. The frayed area is right next to the hole the wires go through to attach to the solenoid coil. In other words I cant fix unless I can figure out how to get it apart. If anyone has figured out how to take the body of the solenoid apart I would love to hear how you did it.
There was a time when my gas filler release solenoid wasn't working. What I figured out was that the manual release was somehow impeding the function of the electric solenoid. While mine never blew a fuse from this situation, maybe a couple of pulls and or lithium grease on the manual release might prevent sticking of the actual solenoid. I did get it to work again and it has been working fine ever since. I did replace the trunk solenoid on a separate occasion. About $300 if I recall for it. A little pricy for sure but it's much nicer to just pop the trunk when you need to do so. If you do replace the solenoid coil, post some pics of the process. The gas filler release one seemed like it would be way more challenging to remove/replace than the trunk bonnet one.
The replacement solenoid from Ferrari part vendors is very expensive. I went to two electronic stores to see if I could find a solenoid that I could modify to work in the car. Unfortunately the local stores did not carry any solenoids that would fit the application. My last resort was going to the local Pick n Pull salvage yard. Since my car is a driver and not a classic I dont care if the part I put in the car is Ferrari part or not (BTW the solenoid installed by Ferrari has no markings). After going through many expensive wrecks I came across a 1995 INFINITEY Q45. The fuel door solenoid in this car was the closest thing I found to a workable solution. The part cost $20 and I installed it with very little modification. If you are going to do what I did you must remember to take all of the hardware that holds the transplant solenoid in place. Do not cut the manual release cable off, and be sure to cut enough of the pigtail (electrical wire harness) for easy splicing. After mounting the new solenoid the manual release cable does not align with the guide tube. If you want the manual release to work you will have to bend the guide tube such that the backend of the solenoid where the cable attaches is aligned with the opening of the cable guide. Hope this helps someone else.

Just pick up a hot rodder magazine and go to the parts sections... These boys have been solenoiding since the'50s. Buy a good, reliable and reasonably priced one and be done with this..or just google.. ther are times when "orgininaity" just doesn't matter..Jacques
Have your fuel lines been replaced since the car rolled out of the factory? Your filler hoses look original and kinda leaky. Fix 'em before you catch on fire! I put the Dave Helms SR kit on my car first thing after I got it... P.S. Blowing a fuse means your electrical system is still working I've got a box of 100 fuses sitting in my tool chest. The day this car stops blowing fuses is when her battery is dead!
