Mystery Part + Mystery Disconnection
Hi,
Mystery 1 first pic I was crawlin' around under my 914 today and noticed this mysterious unconnected thingie right under the rear trunk next to the transmission mount. Anyone know what it is, or how I might use it? My best guess is a selenoid for the electronic trunk release, but it is obviously not working (both wires are cut), and I have a key'ed trunk. Other guesses?  Mystery 2 2nd pic Why isn't this connected and should it be? Only one wire is going into the side of the transmission, the other one is just dangling. Please excuse my ignorance, this is a learning activity for me, but what are the effects of it being connected/not being connected?  Thanks for your patience, more questions coming... bri '74 914 '71 XKE |

My guess is that this was some type of fix for the starter. 914's have a reputation for starter problems and when the car gets hot, the starter sometimes won't crank.
There are several ways to fix this problem and one was is called a "hot-fix" that somehow gets current directly to the starter thru a bypass. I don't really know exactly how this is setup but they sell the kits on Pelican so you might check it out. When I first got my 914, I had the hot starting (or not starting) problem. However, I solved my problem by installing a hi-torque 911 starter - that's another way to fix it. I suspect that your car may have had the problem and this was part of the prior owners fix. I don't think it is for the trunk release. Vern |

Thanks, guys.
I think I will definitely fix Mystery #2, and probably just take out Mystery #1. Since the car is currently not on the road, I doubt I'll have many problems with 'hot' starts...I'll save it just in case I have future problems. Thanks again, bri |

Guy (914GT) your answer made me think about something that you may have knowledge about.
I was wondering if coating the starter with some of that heat reflecting ceramic material similar to what you used on your engine parts would solve the hot start problem? More trouble then its worthI suppose, but I'm curious if any one has tried this . Bill

Pic no. 1 is a universal Ford starter solenoid.
They sometimes help alleviate problems with resistance building up in the wires of the starting circuit. It wont hurt anything having it in there. Pic no. 2 is the switch for the reverse lights. |

How would I go about reparing that reverse light connection? I looked at it yesterday, and it looks like there's a bolt at the transmission that can be undone, but I couldn't get it to move. So what's the proper method of making this repair?
Thanks! |

I've been looking at the schematic for the car, and it looks like there is just one lead going from the relay to the fuel pump (on the stock system), is that correct?
Also, I'm a little confused by some of the stuff in the schematic... What do the T's with the upper and lower numbers represent? How about the numbers at the relay pins? (86,30,85,87) How do I use the "Current Track" section? And finally (for now  , what about the numbers directly on the wires?Thanks a ton guys, you're teaching me a lot. |

Only one wire from the relay to the fuel pump, yes. The ground wire runs straight to ground.
The "T" means "a plastic connector". T12 is a 12-pin connector, T12/6 means pin #6 of the 12-pin connector. The relay pin numbers are a Bosch notation. 30 is the "source"; 85 and 86 are the "switching signal", and 87 is the "output". (87a is the "NOT output", and isn't used for most of the relays in a 914.) For an explanation of the relays, scroll down to "Relays" in the following page: http://members.rennlist.com/damp_dave/electric.html You can consider the "current track" diagrams as a waterfall; in general power comes from the top and it flows down through all the working parts to ground at the bottom of the page. The track numbers on the bottom are merely there to help you locate specific parts on the diagram; you can check them in the "legend" and see the track number, then go to that track and look up until you find the part label. The numbers directly on the wires are the diameter of the metal conductor part of the wire (as opposed to the insulation) in millimeters. --DD
