If you didn't see elsewhere this is a 1970 914 w/ a 327 and 901 transmission. I purchased the car from "Bullit" and here is some info I gotten thus far. The wiring harness is out of a '73; the front end is off a 911 but I forget which year w/ "M" calipers; Trailing arms have some of Foley's reinforcement kit; Engman inner stiffener kit was installed; Griffen radiator;window regulators from a '73; stock 914 1/2 shafts and a lot more which I'll note later.
I'm presently working on the rear brakes and trailing arms and have 2 questions. What is the torque valve for the nut that my torque wrench is attached to; 108 ft lb or 50 ft lb? The manual says 50 for "Control arm bearing/body" and 108 ft lbs for the "Control arm bearing/control arm". Not sure which is which! (IMG:style_emoticons/default/confused24.gif) |

So I'm killing time waiting on the mufflers to arrive and thought I'd take a look as to why the fog lights weren't working. It was one of the last things on my electrical "to do" list. I pop the relay and it tested OK. I had 12.37v at #30's socket so I jumped it with #87 and the lights, well one of them, came to life. I assume the other one has a bad bulb or connection but I could at least confirm that there was a good wire going to the fog light harness. Since the relay tested OK I knew it had to be that the coil side wasn't closing, i.e. a bad ground or voltage not reaching it. So I turn on the lights and check for voltage at #85. 12.37v, good. But no ground at #86. Traced it and the ground was indeed good but when I turned on the fog lamp switch I had voltage on pin #86. Voltage on both sides (IMG:style_emoticons/default/WTF.gif) . So I pull the fog lamp switch only to find that 2 of the 3 wires were crossed. (IMG:style_emoticons/default/piratenanner.gif) I placed them on the correct spades and confirmed all of the light switch terminals were correctly attached as well. Pulled the fog switch to on again and what the Hell? No lights and now my fans are kicking on to boot. (IMG:style_emoticons/default/blink.gif) Pulled the switch again and began to ohm it out. One tab is getting a semi continuity so I ordered one from Bruce today. For the life of me I don't know why the fan controller was energized but I'll wait for the replacement switch before going berserk. There are 2 things I will try if this isn't the problem. 1 is to replace the defective brake switch (currently it is pulled and not connected but it was in place prior to this episode) or reconnect the old blue wire that goes to the generator idiot light. I cut that blue wire close to the fuse panel and used it to connect my temp sender to the fan controller and quad gage. This is the wire that has the diode up at the gage and I may have screwed that circuit up when I cut it. I won't be using that light since I have a single wire alternator i.e. the regulator is internal. It's easy enough to reconnect it and run a new dedicated wire back to the temp sender. Just last week I told Spoke I was a little weary about cutting that wire from the circuit because I didn't know if it could manifest itself into a Gremlin or not. Maybe I should have followed my Gut feeling. Again, I'll wait for the Brake and Fog light switch replacements and if those don't help I'll run a new dedicated line. If that doesn't help I either shit can the fog lights or remove them from the light switch and create a dedicated circuit for them. As far as I can tell, on the #53 relay, #85 receives power from fuse #1 and the Fog lamp switch merely grounds the the relay's coil. If I going at it bass ackwards please advise. On a positive note the mufflers arrived today so I'll have something to do while I await those 2 switches. (IMG:style_emoticons/default/beerchug.gif)
