The car's been running GREAT! Every time I turn the key and this ol' 1.7 fires up on the first crank I think about how this car was built from spare parts. It's been loads of fun and smooth sailing..... until yesterday.
I pulled the car into the shop and decided to take care of a few nagging problems.
Checked the valves (#3 & #4 intakes were 0.009", so I tightened those down).
Checked the exhaust for leaks. Found that a lot of the nuts were loose and the outer nut on #1 had fallen completely off. Took care of those.
Installed some powdercoated valve covers and some special valve cover gaskets I'd been sitting on for awhile.
Installed the wiring for the CHT, EGT, and Oil Press gauges I've been meaning to install.
And finally -- installed a new turn signal switch since the old one wouldn't indicate left turns.
Well, when I went to head home I fired up the car and pulled out. It was just about dark, so I pulled the headlight switch and a few seconds later the car is filling with smoke, and I can see a tell-tale orange glow of fire up under the dash. So I jam on the brakes, turn off the key and jump out and blow out the flames. Since it was already 7pm I just pushed the car back to the shop and got a ride home.
I couldn't sleep past 5am without knowing what happened, so I came in and started pulling things apart. Thankfully only two wires burned, the red power supply wire from the fuse panel to the headlight switch and the white/black wire for left turn signal from the headlight switch to the turn signal switch. My first thought was that one of the connectors under the steering column got installed one pin off, but I found out that can't happen. So I checked the pins on the new turn signal switch compared to the old one, but that was identical. Next I tested the wire to see if it was shorted to ground, but nothing showed up. Finally I physically traced and inspected the wire and found that it had indeed shorted to ground by getting pinched against a piece of metal and exposing the copper wire. What a PITA, but at least it wasn't oversight or incompetence that caused the problem. Just that odd problem that crops up in the weirdest place possible. I really can't see any way that I would have detected this, nor any 914-Life lesson that would apply to everyone else -- other than sometimes
happens.
