Jack's Stupid Bradford Questions - Part 1

[george garside]

Jack, I don't think a water pump would help cooling as the thermosyphon on the twins is near perfect with a very long drop from header tank to cylinders.

'
On the other hand a pump would enable the fitting of an effective heater. I used a Ford export pump ( made for E93a etc) which ran off the outside of the dynamo belt together with a Tudor twin fan heater which fitted nicely on the toeboard. This would be a 'period mod' if you can find one at an autojumble, otherwise modern electric pumps are available but probably use a lot of amps

Jack's Braddie already has a heater, fitted by Ray Milton's dad in the 1960's. It has a funnel at the back of the radiator that sends air down a tube into the passenger compartment. So a fan in that tube would suck the warm air in to demist the windows!

However, the chances of Jack using the Braddie in inclement weather is unlikely.

Another busy weekend, the weather dictating that Saturday was wiring day, and Sunday was filling a skip with bricks, soil and massive lumps of concrete day.

Strangely, both are an exercise of a different sort, and not sure whether I was more content doing the wiring thinking that I could be outside in the pouring rain heffing lumps of concrete around, or whether I was just happy to be out of the house while the chaos of the bathroom continued.

Still, either way we made a lot of progress. The loom was complex, but luckily the wiring diagram was fairly straightforward. We do have some questions as a result, but hopefully these are easily answered:

1. Where does the horn mount to? This was already removed when we got the Bradford, and not sure where it should be physically attached. The wires seem to come out at the bottom centre of the radiator, so assume somewhere near there?

2. Can anyone post a pic of their fuel gauge, or link to internet pic of one which is original? I am fairly sure that the one on the car is not the original one - the poles on the back are vertical, not horizontal as per diagram, and as a result not sure if this is wired up the right way round. Does it matter which way round the petrol gauge is wired up? Presumably it does matter for the wire coming off one of the poles?

3. The big cable from the starter button to the starter motor, can anyone confirm which hole in the bulkhead this goes through?

Finally a nice picture, because everyone loves a nice picture, of the dashboard vaguely in position. I would apologise to the purists, but we've already apologised to them enough for the wheels. You can't see them, but there is a mass of wiring behind it and almost everything hooked up now other than the starter button, which needs some new big cables.

Jack managed to thread the wiring loom through the fan belt which was sitting on the chassis. He managed to rectify the routing problem before I was ready with camera. But we laughed anyway.

CC fuel gauge


On the back of the gauge the left hand terminal should be connected to the sender
Right Hand to the battery. (It is stamped into the back of the gauge)

The horn was originally mounted on the mudguard stay bolt through the engine mounting crossmember

Thanks Steve.

Strangely, my gauge looks like that at the front, but is 90 degree out on the back. Edit - not true. My gauge looks like yours in the photo, however the wiring diagram had the poles vertically and not horizontally. I think I guessed and got it the right way round, but will double check.

Small amount of progress last night before we were summoned to go for dinner. I had been wondering where to fit the battery shutoff. Ideally keeping the engine bay appearance as original as possible (within reason, including the rust!) I didn't really want a big plastic cutoff thing with the big new cables sticking out the back.

Luckily managed to work a solution which is out of the way under the dashboard and the only thing visible from the engine bay is two small nuts (fnar) which are hidden anyway underneath the bulkhead lip at the top. Quite pleased with this setup, though it will require a bit of sorting to get the big cables from the battery to starter button sorted - getting things neat and tidy always seems to be time consuming.

More work to do, as while playing with the big cables freshly bought from the motor factor realised they were only crimped on, and with no effort at all the ends come off. Planning to put some solder in there later on hopefully, as having it securely glued on with lead sounds like a good idea with the amount of voltage and potential for all kinds of disaster if that came loose and touched the bodywork.

Still trying to work out where the big cable normally goes, from the starter button to the starter motor - if anyone can confirm that would be great.

Another day, another set of stupid questions, though at least valid and stupid!

My wiring diagram definitely has the poles vertically, is this a hangover from previous models? Luckily my guess was right and assuming my gauge works same as in steve's pic I am sorted.

Also on the diagram the battery is labelled as 6v. This doesn't seem right, my alternator and various other bits are definitely 12v. Is this a typo in the cc manual? Anyone got another manual just to make sure I'm not going mad and before I take a pen to mine?

Anyway, more gradual progress before the rugby on TV tonight, got the big wires and battery cutoff fitted, lots of swearing getting terminal covers in place to avoid any shorting but worth it now it is done!

early CC's were 6 v early handbooks had only 6v diagram. Later ones had both 6 and 12 v diagrams

I think that you are taking the diagram too literally, the one that I have shows the connections vertically but more importantly identifies the appropriate connections as B (Battery) T (Tank).
It also shows the Control Box with the terminals in a vertical line not horizontal as you find them on the vehicle.
Generally wiring diagrams are just that, they are not physical layout diagrams.

Hi Steve,

You are quite right - the other gauges and terminals were were all shown as they really are, though I didn't see the B and T at first I might have struggled to work that out, I can imagine me guessing T is Terminal

The wiring is making slow progress, but day by day more and more wire is hidden away as things are connected up and wires routed. Entertaining mistake of the day yesterday was wiring up the trafficator wires to the junction box in the right hand side footwell, only to realise that there was a neat hole in the corner that I needed to put the wires through!

Far more exciting than this was the rewiring of the trafficator and the wires to the indicator switch, which resulted in 50% of the trafficators working. The job for this evening is to see if the other 50% will work once wired up, but we were pleased that it popped out, lit up and returned without much cleaning and fixing. Photo to follow, as this feels like something of a milestone and is definitely another step towards roadworthy.

The passenger side, sadly can't work out getting the photo upright but I am sure the magic computer pixies can help:



The next possibly stupid question is rear lights. I am trying to work out what will look ok, provide the most light possible, and also not use hardly any of my valuable electricity. Currently looking at LED bulbs to replace the standard ones, but perhaps trying to come up with something a bit bigger and a bit more, erm, cool. Suggestions welcome on what has worked for others (including indicators at the back) and if there are any legal restrictions I've not thought of.

Also got told off for being an hour late for dinner. As this project continues I can imagine this is likely to become a regular occurrence...

[george garside]

was that dinner at dinner time or dinner at tea time Jack!

However far as back lights I would definitely recommend LED bulbs for both brightness and electricity saving properties. I have recently fitted them to a motorbike with much improvement

You can also buy flexible strips of LED lights with self adhesive backing ( loads on ebay) whch I have fitted to the bike as daytime running lights, They are very discrete when not lit and could be fitted inside back door windows or across the roof just above the gutter etc etc as a safety feature

'Cree' led's are particulary powerful eg 30w output for .8amp consumption

That was dinner at midnight!

So you up North would call it past supper...#

Our IT Consultant, Jack, called on the Pixies who quite simple went to the offending item in the Gallery and selected 'edit photo' and then 'modify photo' and then ' Rotate C90'

The tricky bit was editing the link to Serial number= 5, rather than 2 as the Gallery cleverly keeps copies of previous versions. Alternatively you could delete the old 'IMG' link and put in the new one.

The magic engine fairy was left in the garage for a few hours today, and minor miracle happened.

Engine now starting and running with very little work, though we are clearly missing whatever is between the bulkhead and the throttle - is there some kind of lever? We probably have the part, but we don't know what we are looking for!

You may have noticed the addition of a [video] BBCODE to the posting tabs at the top of the message box. This took me half an hour to add to our bulletin board. Hope you like it!
