Hi Everyone

I need your help in some fault finding

You may know our track Linky to our track

Took the track out the other night to a party

and it worked perfectly

It came back to our club room ( Ok Lee's Garage ) and it played up like a right

I spent time setting up car speed, fuleing rates etc and it ran great in practice

So started racing

FIRST RACE ran ok SECOND Race all speed settings were the same but cars were not showing differences in speed
also several of the cars would cross the start finish line then the next XCLC and stop for no reason

Take car off track after a few seconds put it back and it would go again

Now POINTS Already covered

BRAIDS OK
CAR RUNS ON SPARE PB
CAR ID NOT CHANGING
TRACK CHECKED HOOVERED INOXED ETC

TRACK is running SSDC V5 Latest updated with PPBRO SH

Now if we disconect the computer it runs perfectly

on the saturday night it ran perfectly with SSDC controlling it

So who has any idears

Michael

Did you have the gear in a car overnight before you tried to set it up again? If it got cold and you bring it into a warmer place you will get condensation forming. It is normally a good thing to wait a few hours before trying to use equipment that has come in from the cold.

If that doesn't work then next up ...... I would reduce the complexity of the system to a bare minimum to get a reliable track working and then add bits back in one at a time. Then remove the new piece and try another until you work through the whole lot, one at a time.

 

[Michael363672]

No not in car overnight

was only transported to and from venue

Also it is only in 8 parts anyway as each section is a 6ft routed section
this is what has got me stumped - there is basically noting to go wrong
the joints are by 1 way connectors daisy chaining from 1 section to the next

To me it seems as though there is something either with SSDC or the in car chips

The Nascars have F1 chips in them and it seem like the chip stalls for a bit then starts back up again but in doing so stops the car not your normal run away

I forget, is this the first time you've used fuel load simulation, or do you always use it?
With SSDC (old and new) and the C7030 PB-Pro SH, every once in a while, as a car crosses the SF line and SSDC sends a new throttle curve, sometimes the car will stop dead as SSDC sends another throttle curve (I think it sends it a few times just to make sure it was received). It's probably 1/100 laps, but with 6 cars, it can happen seemingly often.
That problem, however, doesn't leave the car dead. It usually perks back up a second later.

If your cars were completely stopped for a long time, then I don't know what it might be.

 

[GregK]

Have you got at best a ferrite man, at worst nothing on the motor with the F1 chips? You need to have a capacitor as a minimum as the F1 chips are susceptible from electrical noise generated in the motor.

 

[Michael363672]

No Greg we alway use fuel

Is got me stumped too

and other Greg ferite men all in place

 

[RichG]

Hate to ask the same old obvious questions, but...

Are you using Rev F DPR Chips? If so do you have the slot guide & motor supressor fitted?

F1 chips must have the Motor supressor fitted, otherwise with many motors you will get problems as you describe.

Whatever the chip or motor, check you have the motor supressor fitted.

Also what Mr F said?

Rich

Must type quicker................

 

[Michael363672]

They are the solder in F1 chips not sure which rev on them

everthing is fitted as they come out of packet

they stop for a long time

also they only stop if ssdc is running ????

 

[RichG]

You just need to start eleiminating things.

First, particularily with F1 chips, double check that you have a capacitor & ferrite bead correctly installed on the motor.

Next confirm, that everything is fine without SSDC.

Then try SSDC without fuel, to ensure there is no throttle curve updating.

Then go to a full SSDC / Fuel setup.

If anything goes wrong, go back a step.

Can these get damaged over time ??

Also do the chips die or fail slowly over time as these car have racked up some serious mielage

a lap is nearly 50 ft and they will regularly do 800 laps each per race night ?

and we must have run them for at least 10 race nights so far

 

[RichG]

Chips are usually ok or blown, not much of a middle ground. But are you sure the supresors are fitted, and fitted correctly? Have you taken the body off all the cars & checked?

Are some cars worse than others?

Rich

 

[Michael363672]

Yes they are

First up Lee fitted them without them but he has since refitted them

I will double check his work tommorrow night to make sure

Yes some cars are totally fine but the others are problematic

are the saloon chips better than the F1's ?

 

[RichG]

Saloon is better than F1, in terms of suceptability to interference, but F1 is fine with a correctly fitted motor supressor.

Make sure the supressor is wired correctly with short wires. Also keep the motor wires away from the slot guide wires.

However none of this very relevant if you only see the problems with SSDC running???

Rich

 

[Michael363672]

Well that was my thoughts

But Lee assures me that if he turns off the PC it all works fine

Personally I have only run it with SSDC

Will try ang get time to test tommorrow night and report back

Thanks so far

 

[Michael363672]

Morning all,

A quick update

Spoke to Lee this morning and the cars in question now have SALOON Chips fitted these are the solder in type not DPR
But only have the Ferrite man etc on the motor end and still have issues so will try and fit to guide end aswell

If anyone could post up a PHOTO here of where to fit them for him it will be a help as these are the only solder in one he has

He has also put together a set of DPR NASCARS so will be able to test both of them side by side tonight

Michael

 

[GregK]

Have a look in the Chipping Database section, there are no end of photos showing the wiring. It is probably better to fit the Ferrite Man to the Green & Yellow wires and put a 103 capacitor across the motor for the red & Black wires.

A 103 capacitor is 10,000 uF in size.

 

[Michael363672]

any idear where we can spares from ?

Do Maplins do them thats both bits

If they do and anyone has a part no I can send him shopping lol

Thanks Michael

 

[GregK]

PM your address to me and I'll pop a dozen in a bag for you.

Cheers - Greg.

I would not compromise the motor supressor as it is the most important of the two. If you want to add suppresion to the slot gude, which except in the case of a Rev F DPR chip is of little value, then buy additional components.

However if you already have Saloon chips & full "Ferrite Man" on the motors, then the cars should be fine. So probably looking for a problem related to SSDC? If that is the case try without fuel / throttle curve updates & see if that fixes the problem?

A 103 Capacitor is .01uF 10,000uF is very big

Rich

 

[GregK]

A 103 Capacitor is .01uF 10,000uF is very big ........ it's VERY,VERY BIG, in fact as big as a big thing can be!

Indeed, it would be downright dangerous, beside which, it probably wouldn't fit inside the car ............

What I should have typed was 10,000 pF (pico as opposed to micro).
