Topic: Help, my son reversed pollarity...

[biker550_uk]

We have only owned this for a few hours but in the hast to try it he got the wires around the wrong way.  There was a burning smell from the POD.  Ive had a look inside and R10 is very black, and according to the circuit diagram it is a 10ohm resistor.  Does any one know what wattage it was and if it was wire wound or film? Also if its likely to have done any other damage as the fuses in the main control box are fine.

Also BEFORE the above disaster happened we were trying to sort out the rear lights as when we looked at the C5 it worked however after the journey home it didn't.  The bulb is fine and there is no volts getting to either front or rear lights.

Hope fully the only damageto the POD is the resistor, most of the damage is going to be in the Control box.

Check the 5 volt regulator, and the resitor below it ..

Also look at the diodes D1 etc

Parts and replacements are shjown in the tech section of the forum, also you will find some info on similar probelms.

To prevent this happening, its a good idea to fit one of the replacement power leads from the c5alive shop.

Hope this helps, let us know how you get on ....  Lots of helpful people on here will soon get you back up and running.

Re the lights check the connections in the contyrol box for the lights, sometimes the pins in the connector get a bit tarnished, also the track on the rear of this connector can some times crack around the solder joints.

This is probably going to sound strange but im having problem locating a 10ohm resistor.  Do know if this is a 10ohm for sure and what wattage it would be please?  I will check the other bits once that is replaced and cross my fingers.

[PLOD11]

This is what you are looking for on the control board re the lights if the solder joints have cracked.

r10 in the pod is 220k

[PLOD11]

r21 tends not to like it when voltage is reversed, that is 10r, is this the one you are looking at ??

[PLOD11]

maplins part no   M10R

[biker550_uk]

sorry everyone it was supposed to be R21 which is a 10ohm.  Maplins have no stock of any of these resistors... typical Ive tries even for getting two in parallel.  I will try some other sources later today.

[biker550_uk]

Ive replaced the 10R in the POD and also the 2 R 2  in the control box is blown so i would assume the 5v regulator is also blown.  Is there a maplin equivelent or is it only the farnell one as over £5.00 is a little steep for postage... if not i will just have to swallow it....lol

[mikegrifter]

hi

 i work for rs components, have you tried rswww.com

they do charge 4.95 for delivery but if you let me know what your after i can get it for you and always post on to you myself

[PLOD11]

A 7805 from Maplins will do the trick ....  But also see below. 

I normally get most my bits on E bay, you end up wih loads of spares, but a lot cheaper.

Hi every one thanks for you help so far.  Ive replaced D1 and R1 in the main control box, and R21 in the pod.  Every thing burst into life for a brief moment apart from all lights on both sides are on the pod.  We then managed to blow another D1 for no apparent reason.  After this no motor function at all and all the pod lights are still on.  Ive checked the main control box 5v regulator and this has 0v in the middle 12v on one side and 5v on th out side.  R1 is still fine and in tact and so are the two fuses.... Any ideas ? getting desperate now....lol

UPDATE! im getting 12v on x13 and x12 when pressing the handle bar switchthere is 12v between the red and black terminals on the relay but no click from the relay or sign of life. Using the negative on the battery for the black probe ive got +12v on both the red and the black terminals on the motor at all times.

I would check  D4 then replace  lm358, i would fit a socket to this and then its easier to replace in the future, and maybe the ztx 449, the latter might be hard to find . Have a look at the current parts listing i think there was an alernative listed which had been tried and tested. I have a spare one here if you need one.

[biker550_uk]

Just looked at the parts list and there are alternatives listed.  This is going to be a long process keep waiting for these parts...lol.  Do you know if the c5 works with out the pod connected, just so i know that the pod fault is a seperate one and not part of the same thing?

Thnaks Again... Brian

[PLOD11]

Some one else may be able to answer that one, i know it is possible to link out two pins on the connector at the POD end, but have never done it. You could do with a known working POD to swap it with really.

I wouldn't think its damaged the pod other than the Resistor, i think the problem is going to be in the Control box.

The lights on the pod problem i would say is linked with the Control box fault (assuming it was all working to start with) ?

Where are you loacted ??
