As told in the welcome section, I'm trying to put on the road my C5.
I'm waiting for new tyres and tubes from a local bike shop, so this evening i went to the garage to see how to proceed and take some picture (sorry for poor quality, i used my mobile phone). :(
First of all: i washed the C5 using a strong degreaser (Resol) and a rough sponge, so now i discovered the underlying white ! ;D
Also the bar installed under the shell for two days has done the job, and the twist on the shield has finally been straightened.

Here are all the items I've found in the box:
(http://img218.imageshack.us/img218/8373/c51.jpg)
the only item missing seems to be the battery cover, so i have two ignition switches hanging to the cables: i will build a sort of new cables to connect the battery (or batteries).
Finally i dismantled the power electronic and i discovered a point of fault at the connection of RED output motor cable:
(http://img341.imageshack.us/img341/3922/c54.jpg)
For unknown reason, in that point the cable overheated and burned the PCB area, destroying also the near diode:

so must know the type of diode to replace it ! Then i will try to strengthen the burned printed circuit soldering it.

I believe that the blue cable is NEGATIVE and the brown is POSITIVE, right ? :)

Yes you are right brown Pos and blue Neg ....
That Circuit board looks in a bad way, but is repairable.
Have a look here for the circuit diagrams for the control box etc, this will help values of components.

Hi the diode is an 1N5401 ie the commutation diode - just replaced a burnt out one myself - the burning may be the result of the connection becoming loose and 'arcing'.
-
glad to see that your Porsche is Guards Red, same as mine.
-
coverman that Porsche is not my car, it is a frined's racing 911 that i hosted in my workshop for the night before a race.
I restored the C5's control unit replacing the commutation diode and the connection plate:

I rebuild the plate using a 2mm aluminium bar, shaped and drilled as original, but i guess that the electrical characteristics are a lot different from the original item.
I read in the "Unofficial" documentation, that this metal plate must have a specific resistance (very low), so i believe that this new alu plate can't be adequate for the circuit ... :(

You have a very spacious workshop even if the Porsche is not yours! I am not brave enough to tackle repairs to the control box so your work is admired.
-
I think an aluminium plate shouldn't do any damage, but due to the current going through it there is a possibility it could melt. A piece of steel should be fine, as that's what I think the original is.
It's not a specific resistance, you're thinking of the current shunt near the bottom (different piece of metal with 4 connections to it).
I notice that there's a replacement fuse in your box from that picture, might be worth checking to see if it's the right value, a fuse which isn't clear usually means it's a household fuse, which certainly shouldn't be used in a C5! (possibly led to the burning issue it's had!)

You have got three great classic cars in your workshop, do you specialise in VW's as I noticed the front of a camper on the wall up high I think ?

You have a good view, it is an ald front of a Samba Bus

that actually we are restoring. :)
Incidentally, last month we bought a '69 Beetle ... ehm ...

After the stop due the summer holidays, works around C5 started again.
I completely disassembled the vehicle and restored the frame. It was a bit rusted and the paint disappeared in various areas, so i treated it with sandpaper and then with Fertan (specially on rusted areas)
(http://img38.imageshack.us/img38/9320/c5ap.jpg)
(http://img80.imageshack.us/img80/4464/c5bb.jpg)
and then resprayed using a very robust paint (specific for car's wheels)
(http://img255.imageshack.us/img255/6291/c5c.jpg)
the fork has just painted with primer.
I also bought new tyres and tubes (Kenda because Schwalbe aren't available in Italy)
(http://img441.imageshack.us/img441/4687/c5de.jpg)
... and a little temptation ...

looking good so far mate 8)

Hi, if that Kenda tyre is the same as I have on my front wheel., it has a maxiximum inflation pressure of 36psi. Mine would come off the rim at 40 psi, but at 35 psi survived 2 laps of the Brooklands circuit ( at a speed a racing tortoise would have been ashamed of). I run Schwalbe rear tyres at 55psi( as my gauge won't read to the 60 psi maximum permitted). This high pressure removes the likelihood of much sidewall compliance hence reducing the tendency to roll
-
Although the Schwalbe tyres cope with the higher tyre pressures, I'm not so sure the plastic wheels cope all that well.
Adam Harper always recommended sticking to the original Sinclair figures...I compromised and stuck with 40psi for the rear.
Fitting a steel front wheel permits higher pressure at the front.
-
Looks like its going to be another nice C5 back on the road when you have finished, please keep the pictures coming of it and the VW's.

My Kenda tyres reports 40 psi for front and 65 for rear ...

Friday has arrived the rotor for front disk brake mod !
Yesterday i've machined off a fraction of material from the wheel to slip the disk in side and take some measurement to invent a decent locking system ...

I second that, it does look good, i might try something like this my self.

I straightened the distorted rear axale (wheels turned obviously wrong): i placed it on the lathe and gently pushed it using a press:

Looking better than new 8)

great work, looking at the pre assembled picture, made me wonder if fitting another chain tensioner to the upper upper legnth of chain given how long the expanse is, when your not peddling at least the chain is held better over bumps.
does anyone feel there would it be a bennifit?

Finally the shell re assembled to the frame.

The windshield is still a little distorted, so i'll try to use a thermal gun.

ahah ... yes it' a nice calendar distributed by "Quattroruote", a popular italian car magazine.
I love Mini, i have got a '82 Austin Mini Clubman Estate ...

A c5 and a mini - you have excellent taste 8)
Excellent job on restoring the c5 , it looks superb :)
-
The C5 looks really good, top job mate, and the mini is really nice too, look after them :)
Retro Andy.

Many tanks ! ;D
After C5 pimping, next step is a new disk brake mod for my Mini ! Original drum brakes does not more guarantee adequate performarces for new 1330 Cooper engine ... ::)

That Clubman looks lovely, I bet the Italian weather is kind on the clubby too. I own a 95 Mini Mayfair(currently under restoration) :)
-
Just the Italian job ;D

In the afternoon i rebuilt the control box and tested the electronics and motor: just connected the battery on X1/X2 the pod lights up (first+last LEDs on left gauge and all LEDs on the right).
I tried using the little bike's battery: when pressed the motor switch, the motor has started @6A with no load and the second LED (green) of the load gauge has lit. When the battery voltage reached 11.8V the buzzer is started then after few time the motor has stopped.
I do not understand what they are the X7/X5 on the control box, and how to put all the C5's electronics under the key switch to avoid to disconnect/connect the battery when the vehicle is parked.

I think Chas, Marty or Plod are your best bet for an answer mate. My knowledge of lectrikery is not the best ;D

Haha ace, hey Alex do you know much about 70s Italian police films?

ahaha ... yes i like it a lot.
In Italy the genre is called "polizottesco" ("Milano calibro 9", "La Polizia ringrazia", "Roma violenta" ...) were a lot of Honda Four, Kawasaki Mach III, Alfa Romeo and Citroen DS running crazy (but no C5).
:D

Hehehe I've been watching a lot of them lately. Films like Manhunt and The Big Racket. I own an Alfa myself so you get to see plenty on them. It's tricky trying to find them dubbed or subbed into english.

Haha that's a good use for those. I usually take them out of PC cases. Also I watched Street Law last night, it was superb!

I seen that cone yesterday, bolted in a discarded case cover and i removed it and later i tried to install on the C5's motor: it fit perfectly !!! ;D
Now i taken a PC 12V fan, so i'll try to put on.
"Street Law" in Italy was "Il cittadino si ribella" (approximately: "The citizen gets mad").

A great Franco Nero ! ;)

I shall start a polizottesco in the off topic section and we can talk there 8)
-
Yesterday i tested the C5 around home: it is very amusing ! ;)
The new 40Ah gel battery does not take all charge anymore, so the duration of runs is still limited ... moreover the battery "monitoring" strategy of POD does not help: the gauge can only decreases and sometimes it buzzes and disconnect the motor, so must cycle (on/off) the power to have a new full gauge ...
The other problem is the load indicator: with no motor activated, firts+last led lights, but when the motor is running only the first (green) led light. No other led never light, even wen the motor is under heavy load ... :(
... ULA damage ?
