From Veeduber@aol.com Wed Oct 11 01:41:45 1995 msgnum: msg17304 Date: Wed, 11 Oct 1995 02:41:42 -0400 From: Veeduber_at_aol_dot_com Subject: Grendel, Tuesday III Rain. All through the night and into the early afternoon. The brake light switch arrived as promised but there was only one of them; only one had been ordered. I thought I ordered two; I can't clearly recall. I installed it in the rain, wet but not rained upon under Grendel's bulk. The blue-eyed cat joined me, head-dived against my watch-cap, finally sat and watched the rain. It seldom rains in Egypt. With the switch installed I was ready to bleed the brakes but had no one to pump the pedal. Began tracing the brake-light wiring. It runs into the loom of wires that was burned, vanishes. I've picked it out of the loom running through the fore & aft frame member, know it's good from there back. I track the wily wire into the mess behind the turn-signal relay and suddenly realize that failure of one will effect the other -- early buses use a two-light system, the brake light also serving as the turn signal. My host arrives home for lunch and helps me bleed the brakes, happy that three of them bleed properly, unaware of the portent of the one that does not. The driver's side front flows neither oil nor air when I open the bleeder valve, yet I can hear the upper cylinder actuating. This is the one wheel I've not rebuilt. Grendel is paying me back for my neglect. But it's the brake lights that bother me. And the turn signals. I put on my thinking cap, scratch a schematic on the back of a receipt, mosey down toward the harbor and the nearest FLAPS. I ask for and receive (surprise!), a double-pole, double-throw center-off switch, a heavy-duty two-terminal flasher unit and a pair of after-market tail lights, the kind with a two-filament bulb. The bill is about twenty-five bucks. Back at the house I dig through my spares, find all my wire, select a roll of #14 and two of #16. Tie the ends together and nail them to the fence, start backing up, paying out the wire until I reach Grendel's stern. Hang a right, keep backing down until I run out of blue wire, hoping it will be long enough. Put the cast off brake drum on the wires to keep them from coiling up, go back to the fence and start looming them together with electrical tape, my last roll of the stuff. Twist, twist, twist, wiping the rain from the wire as I wrap it with tape, shielding it from the sprinkle with my head and shoulders. Twist, twist until I reach the brake drum. It takes a while. The main fore & aft wiring harness for the VW bus runs through the passenger-side frame member, up and over the torsion tubes, a well protected place but difficult to pull new wire through. I try pushing a piece of bailing wire through the frame but it fails to clear something. Try it from the other end but it hangs up. I'm laying on the damp ground in my damp clothes, head and shoulders protected, under the bus, legs getting sprinkled on. Is heavy gauge stainless steel safety wire stiffer than bailing wire? It takes a while to unspool enough but once it is straight it proves stiff enough, if pushed through from the middle of the frame member. I lash the loom of wires to it, pull them through, do the same with the rear half of the frame member. I now have three new wires running from the front to the rear of the bus. It takes over an hour to loom the wires and get them threaded through the frame. Up front, I make up connectors and put the #14 wire onto the brake switches. Use the safety wire to find a path up into the cabin, pull the ends of the #16 wires up near the turn signal relay. It all takes time and I'm getting wetter. Climb into Grendel, turn on the trouble light and start the engine. Out of the wind it feels warm, even if it isn't. In a few minutes Grendel is blowing a faint breath of warmth around my feet. I think I've blocked my new heater duct with the foam meant to insulate it. If so, it's going to stay blocked until I get home. I start making a new turn signal. A DPDT switch has six terminals. It's really two switches in one housing. I will wire the hot lead from Grendel's defunct turn-signal relay to the center terminal on one half of the switch, wire the switched power from either side to the flasher. The output of the flasher goes to the center terminal on the other half of the switch. Push the switch to the left, the second-half left terminal will have the flasher's signal, push it right, the right will have it. Simple flasher system. I do the wiring and begin gnawing a hole in the dash. There's already a hole there but it's too small to accept the threaded neck of the switch. My gnawing tool is a small drill and Swiss files. It takes longer to make the hole than it did to wire the switch but I'm out of the wind, thinking of Baja and beaches without footprints. When I found Grendel's tail light fixtures to be damaged I removed them and installed a pair of boat trailer light fixtures in the holes, first making up cover plates to close the openings. Now I dismounted all that and figured out how to mount the second pair of tail lights, the ones I'd just purchased. The only way they would fit without drilling holes in the body was to reposition the first pair and mount the second pair above them. I drilled the necessary holes in the cover plates, kneeling in Grendel's cargo bay, drilling atop a block of wood. It was dark before I was through; I knocked off about eight pm, went in to eat and warm up, get dressed for working in the rain, which was coming down again. To install the fixtures and wire them I worked sitting on a piece of plywood, the wind blowing down my neck, dressed in a garbage bag and wearing a turban. Some folks would call it a towel wrapped around my head but it was really a turban covered with a small white plastic garbage bag. The neighbors arrive home form somewhere late, mutter to one another, go into their house without speaking to the strangely bundled creature squating behind Grendel's engine. I have the trouble light and my timing light inside the engine compartment, protected from the rain, as are my tools. I'd be there too if I could figure out how. The work took about two hours. When I was done I was so cold I had to roll onto my knees before I could stand. I loaded everything into Grendel, wiped down my tools and sat dripping as I tested the circuits. The two #16 wires were for the rear turn signals. I connected them to the front turn signals and to the output of the DPST switch. Got it right the first try; left was left, right was right. And brake lights, too. The turn signals were wired to the bright filament of the upper fixture, the brakes to the lower, running lights to the low-power filaments of both. The result is perhaps the most visible '67 Volkswagen bus on the planet. Clunky as hell of course, but it works. I mounted the switch horizontally; flick it to the left for a left turn, right for right, center for off. No self-canceling, no indicator lamp. I'll do it right when I'm home and dry. Tomorrow I'll insulate all of the connections, tighten down the fixtures, check things out. But I've a hunch Grendel is about ready to roll. I need to fill the tranny and check the toe-in but other than that, she will pass any highway safety inspection. Even mine. -Bob
