A Dash Of Fun

Today started out with a plan (as most days do) Go to Napa get some paint, go the grocery store get some milk etc… I started out thinking I would paint the dash panel today and that would be the end of it. Well as John Steinbeck said The best laid schemes of mice and men / Often go awry” and that is precisley what happened to this man. I did get the paint and I did paint the dash panel. I then decided to see if it would fit… it did. So far so good but, now the launch sequence had been activated and I new what I had to do. Knowing I had taken many photos of the wiring and that everything works I decided to put it all back together. I started by disconnecting every gauge so I could fish the harnesses to the proper locations. then I remembered the windshield washer hoses were pulled off waaay back when and were rotton and needed to be replaced. So back to Napa I go. Once back home I needed to install the hoses and feed them through the firewall. I reached around the column but could not locate the little connectors which protrude from the back of the column. That is when I decided to take the column off and make it easier on myself. This is were “oft go awry” comes in. When I pulled the steering column the spline steering shaft which connects the steering coumn to the front wheels, fell onto the floorboard. CLUNK I examined the situation and saw that the shaft was not even bolted in… on either end. Good thing I pulled it. The hoses went on fine and by poking a screwdriver through the gromet from the other side and slipping the rubber tubing onto the the blade (from the inside) I was able to pull the tubing through the grommet and the rest was easy. I started with the speedometer and worked my way toward the fuel gauge. it went back together surprisingly easily and I felt confident it would work. It does.

 

Everything Is Illuminated

Wow! You ever have one of those days where things just sort of fall into place? Even intermittent problems can be duplicated? Today was a great day for wire tracing. It started  by me deciding I was going to figure out what is wrong with the hi beam indicator. Remember I said the indicator was dim all the time?  When I tested the switch it was just dark enough in my garage to notice the indicator got just a tiny bit brighter when the hi beam switch was activated by the lever. At the same time I observed the head lights were going to low beam…. Ah Ha! Could it really be that easy? Yes! I changed the hi and low beam wires on the head lights and suddenly had a hi beam indicator which shut off when when the lights are in low beam. It’s the little things that make it all worth while. Not only that, when I checked the schematic I suddenly saw why the fog lights were not working. I pulled the switch and Viola!…  Lets not get cocky, The fog lights were a two fold process as there was a loose relay (two actually) but  Prospero’s schematic and the good ol Haynes manual gave me the road map I needed to figure it out. But wait there’s more! Since I was on a roll I thought lets see if I can get the parking brake indicator to light.

It blinks! It is connected to the flasher. “OK lets do something challenging” I said  “How about the parking light indicator… too easy… how about the fuel gauge!” Then I was done talking to myself for awhile. On the 914 there is a light that tells you your on reserve when your almost out of fuel. It is normally switched on by the fuel sending unit. I learned my lesson from EVIE so I did not go crazy and remove the entire wiring harness when I stripped the car for paint. Everything is pretty much stock.  I found the fuel sending unit connector and did a quick continuity check to locate ground. A fuel sending unit  is nothing more then a variable resister. At the top of the fuel level “topped off” the resister is a short. As fuel is used more resistance is applied using the float as a mechanical means of varying the resistance. Once the potentiometer gets to a pre programmed resistance another switch is activated which lights the low fuel light. Since the 914 has a neg ground I just needed to figure out which contacts in the connector were hooked to which color wire. Since there were only three wires total, and I already found ground I had a 50/50 shot at getting it right. I made a jumper and as you can see in the photos it worked.

That worked out pretty good. I am going to put some photos of the wiring to the emergency flasher and some other interesting photos that would have been helpful to me. Remember this is a 1973 914 and has a wiring harness for a 2.0. Here they are…

So very soon I will put all this back together knowing everything works.

 

It’s March!

I have been very remiss about posting so there is much to catch up on. The headlights work perfectly as do the directional lights. The side markers work as well. There is one hitch in my giddy up though, the directional light indicators on the tach both blink at the same time. in other words if I pull the directional light switch to turn on the left lights, both right and left indicators on the dash blink together. The same is true conversely. The only thing I can think that it might be is a misplaced ground wire in the directional light circuit. I have checked all of the switch wiring and the fuse panel wiring and as far as I can tell (If Prosperos schematic is correct) everything is hooked up properly. All of the lights in the front of the car have good proper grounds, I will next tackle the tail lights. It is odd because my fog lights have also quit working. When i pulled the motor and partially disassembled this vehicle for painting everything worked except the heater.  Now besides the above mentioned my indicator light for my high beams stays on all the time but very dim. I will resolve this and get back to the business of electrifying the ice. The hood is back on and I pulled the fresh air fan. the motor is toast. Hopefully one of the other 914’s has a good one.  Oh yeah I forgot to mention I bought back the two I traded for the paint job. Anyone interseted in a fair 1970 roller? A running 1975 914?
