Hi
Bonhams could afford to pay you to take the Dodge and the trailer down to display alongside it. _________________ Bristols should always come in pairs.

I'd rather have the Dodge than the Alfa.
Hired an Alfa once, which had 33Km on the clock. It broke down the next day and had to be recovered by the Italian equivalent of the AA.

Hi G,
I've been pondering the fuel gauge today, or rather the connections to and from it.
It would appear that
a) it's been wired incorrectly, and
b) the senders aren't right.
The senders should have two terminals on them, connecting to the two live output feeds from the gauge ("1" and "2" on the factory wiring diagram). The senders that are on just have the single connection, like on most cars I've come across. Do your Dodges have single or twin connections on their senders?
Can you point me to anyone (Dallas Autos perhaps?) that stocks the correct senders, with the two terminals on them? Looking at the old photos, the original senders had two connections on each.
Thanks, R _________________ Rick - Admin

If I understand it right you have the original three terminal dash gauge, but only single terminal sender units on the tanks?
I always used to tell people you couldn't mix and match the senders and gauges between the two wire and single wire systems, but apparently you can.
You'll probably need to e-mail Dave Fenner ( jobrated man ) on the 39-47 Dodge Truck Group on Yahoo for absolute clarity, but apparently if you ground the tank sender to the tank to the frame, you can use the single terminal sender to the number 2 connection on the dash gauge and it'll work.
This is a recent message from Dave;
------------
Ok to use it. Be sure to ground the sending unit with a wire from one of the screws to frame; then connect stock wire from #2 terminal on back of gauge to the center terminal on tank unit. Do not use the #1 wire at all. It will work that way.

I'd check with Dave before you did anything though. I suspect Bess originally had two-terminal senders on each tank, and a matching three-terminal dash gauge, with some sort of double pole changeover switch so you could read from either tank.

Very interesting, thanks G, yes I have three terminals on the fuel gauge, and one on each sender. I'll take a look at Dave's suggestion and see what gives, I'll call by the 39-47 Register too.
thanks, RJ _________________ Rick - Admin

The experiments with the fuel gauge came to nothing, so it was the turn of the fuel supply to be looked at again.
In recent road tests the carb has been running short of fuel, with the result that the truck coasts to a halt at almost the same location down the road, whenever I've taken it out for a spin. Static running, or backwards and forwards in the drive, were no problem. Turning off the ignition and back on again would have the electric pump chunnering away for a while, until it had filled up the float chamber again.
Various alterations didn't make much difference.
During the resto, the supply was set up the same as it had been in the years following WW2, ie:
two tank feeds (one per tank) -> forward, pipes up the bulkhead to a change-over switch -> one pipe to the electric SU pump (used for priming) -> down to the mechanical pump -> carb
I tried going from the electric pump straight to the carb, bypassing the AC mechanical pump, thinking that there may be a conflict between the two pumps occurring, but that made no difference.
It's now set up like this, just running with the o/s tank for now:
one feed -> mechanical pump -> carb
I've a feeling that there was a vapour lock forming where the pipes ran up to the change-over switch, starving the carb of fuel. Plus this new arrangement means there are fewer pipes running near to the engine, which can't be a bad thing.
Yesterday I took it to the local pub meet, its first run out since making the changes. The weather was showing 30 degrees C, so a good temperature in which to do the testing. It drove there well, pulling strongly and no hint of fade. Equally the return trip I gave it a bit of welly for a few moments and it pulled like a train. Hopefully this much-simplified fuel supply will improve on, or eradicate, recent problems I've been having. Time will tell on that one, but the signs are positive....fingers crossed.
RJ

Electric pumps = useless.
You need two tanks, changeover, and one mechanical pump. You do need the mechanical pump to have the hand priming lever though. Just need to be in the habit of opening the bonnet, two or three tweaks of the hand primer, and start her up. |

To be honest I'm happy running off one 20-gallon tank and no change-over for the foreseeable. A priming lever would be handy, although it didn't take much churning on the starter to fire her up yesterday. The pump is an AC Model D.

I'll have to admit that I have been known to cheat and use a small bottle of petrol, squirt directly onto air cleaner - but with an updraft carb you need a primer.... |

|

Quick update.
As mentioned elsewhere, on Saturday the truck was taken on a local test drive which amounted to about 6 miles. Doesn't sound far, but it proved to be a useful test. As it went ok, plans were set in motion to take it to the vintage rally over at Malpas, which is 12 miles away.
The drive over on Sunday went without a hitch, its longest single trip to date under its own power.
Driving it is quite interesting. The overall gearing is surprisingly low, especially as it has a five-speed 'box (but only a single speed rear axle). In deference to the amount of work the engine needed to get it running, I kept the speed down to about 30 tops although it would have gone quicker. Bearing in mind that road-registered lorries after the war were restricted to 20 anyway, sticking to 25-30 seemed appropriate. The noise in the cab is quite impressive, although as there's no sound deadening or even floor mats in there at the moment I can't complain.
Trickiest to deal with is the steering lock, which isn't the best in the world (how it compares to other vehicles of this size though I don't know). It took a little shunting back and forth to get it into the rally entrance, same again when it came to parking up - although other coaches and long-ish lorries were seen doing the same. Just something to get used to, old commercials require a different mindset to the straightforward task of driving a car
It pulls really strongly up hill, and the torque means that downshifts from 5th are rarely needed even at roundabouts, so long as you don't come to a complete halt.
The servo brakes are very powerful, and surprisingly light.
Bar a small local show a couple of years ago, this was the first large car/lorry/vintage/steam rally it's been to under its own power, so that was pretty satisfying. Annoyingly most of my photos disappeared from the camera when I tried to upload them this morning, but a few were saved.
The weather was ok for the most part, although occasional showers did make themselves felt during the afternoon.
At 2.50pm it was time for the commercial section entrants to go for a pootle around in the display ring. We followed a particularly smelly and smoky diesel breakdown wagon (not shown), so held back as much as we could to avoid the smog.
5.00pm and we joined the queue to leave. This was a good test of the cooling system and there were no issues at all. Once a very tight exit gateway had been negotiated, we set sail home. During the run we overtook 3 or 4 steamrollers which was entertaining, and got back home in good time.
Overall a good day out, and probably for the first time everything was given a useful extended workout.
If anyone here has any shots of us driving around, it'd be neat to have a copy if possible? Thanks.

Hi Rick,
you need to drive her more
Old cars dont like being left sitting.
This summer have I been driving the WP more than any other year (some years it wasnt even out
anyway, what I want tosay is = a restored car loosens up, and everything start to work together as it should,
when you use it more.
You will soon feel a big difference
