Hi,
I've been trying to get a C5 up and running for a while. it was in pretty poor condition when i started and had many burnt out componants and burnt tracks on the boards the 1A fuse had been bypassed. I have tried many things but still can't get the motor to run. I don't even get a click from the relay.
Some things i have tried are:
replaced all componants in control pod
repaired burned tracks
new relay
new transistors in pod
replaced r21 in pod
cleaned all contacts
tested red wiring loom
12v to x2/3/4 and both sides of r1
12v to lm342 and 5v out
Any help would be greatly appreciated as this is driving me crazy!
Cheers
Tom

Have you tried connecting a battery directly to the motor to see if it turns?
-
Hi there just as Kamilb say's First thing is to make sure that the motor works ....The brushes some times stick ...
Bye Chas
Where do you live .....
-
Yes tried the motor direct to the battery and it turns. sorry should have said that.
I'm in solihull
-
Do you have any display on the Pod ??
Have you checked all wiring, especially the red wiring loom between the pod and the control board ??
Also all contacts /pins on the POD may need a good clean.

I think the pod is normal now ( when i first attached a battery it was a dull glow of random lights!) the led's are all light up on the state of charge side and on the other i have two amber lights and when i press the microswitch i get one green aswell. ive given the contacts a good clean and tested the loom and reseated the wires at the pod end of the loom. however, the lights sometimes go out when i move the the control board.
I have the whole eletrical system removed and on a bench.
Thanks

These boards suffer from dry and broken joints around the pins that solder through the board, might be something else to look at.

Thans John.
I've tried renewing the joints in the pod and removed and replaced everything on the control board. I guess there must be some sort of bad connection for the lights to go out. Might try reseating the wires inthe connector at the control box end. Everything was quite coroded when I got the C5. I think everything had been left open to the elements for many years.

The damage you are describing sounds as if there has been a reverse polarity connection - this could have damaged the ula giving a non run condition - i had this exact same fault on a c5 last week - if u want to post the pod to me covering the return postage - i will happily test it for you - Marty
-
ps also check the fuse holders are making a good connection as they can play up after fuse changes
-
Have you changed the op amp in the control box ?
-
Hi,
I had a a problem with the fuse but have sorted that. I was under the impression that the motor would run without the ula. Is there any way I can bypass the pod to make sure that it is the problem? I will have another look at it tomorrow but think I might have to take you up on your kind offer.
I have replaced everything in the control box.
Thanks
-
What power source are you using to power it up, are you using a Car battery or similar ??
Reason i ask is that a while back someone was testing on a bench and there power source was not up to the current being drawn.
This would give similar symptoms, ie all lights appearing to show correctly but nothing going on at the motor end when the button was pushed.

Hi - Plod makes a good point - once that has been clarified and if you are still seeing the fault - drop me an e-mail and i will forward my address - prob best to send me the pod and control box - marty
-
Thanks John, I was all excited this morning when I checked the battery and found it was only 14Ah. I've tried a 40Ah battery and still no joy. Guess I'm going to have to admit defeat and take Marty up on his generous offer.
I'm suprised at the level of help you get on this forum.
Thanks everyone.

Address sent Bud - sure it won't be much - sounds like you have done all the hard work :) :) :)
-
Just a thought as you are bench testing - have you both sensor wires for the motor (orange/orange) (grey /Violet) connected in the control box ?
-
As Marty says, it wont be much, dought it will be a problem with the POD as all seems to working in the display area.
We have all been there with our first C5 and getting it running, lots of experience on here and all a very friendly bunch. 8)
Getting it running is all part of the C5 exerience ... :D

Hi
all conections are in place. if i test with a meter on diode test function i get a beep across the orange annd a reading of 1900 across the thermistor if that means anything?
-
Sounds about right - pop it in the post and we will get it sorted
-
Marty
If you e mail me your address i will pop that item in the post we spoke about at Santapod (Code word "VELCRO") ;)

Your a top man Plod - don't care what anybody else say's :) :) ;) :D ;D

hi,
Had my control board and pod board all nicley bubble wraped in a jiffy bag ready to post to Marty tomorrow, then i just happened to see an image of a working control box with the thermal cut-out in a different position to where i had it. When i received the C5 it had alot of wires unplugged so I used the wiring diagram to show me where everything goes. The way it looked to me on the diagram is from left to right it should be thermal cut out to the left 2nd battery in the middle and thermistor to the right. So that is the way I have had it. I unwrapped the board and reassembled it (correctly this time). Eureka it works!
I would like to thank everyone for their help.
Cheers

Well done! 8)

Thanks.
I wouldn't have stood a chance without the information and help from here.

Well done mate ..... 8)

I was nearly there lol - great news bud and the satisfaction and knowledge gained in getting up and running yourself - well done bud :) :) :)

Arrrrr the simple things in life...............................
Glad you got it sorted

Well done keep it up I may send you some of my control boxes for repair bye Chas
-
Thanks. Would be happy to look but you know what they say "one swollow doesn't make a summer" I've got loads of spare Componants if anyone needs them.
I also tried a couple of alternative componants, so will post them if all goes well in the long term.
-
Have a look at the list in this thread, any alternatives tried and tested can be added to the list ... ;)
