If you have a multimeter or can borrow one it would be easy to track down where the problem is. If the powerbase flags a short then a multimeter across the rails should confirm it. To check if it is the powerbase or the track, you would need to take it out of the circuit and test both again independantly.

What difficulty running analogue cars?

Just to add the pair of crossovers turns are fine and and should not be confused with the lane changers turns.

You have only one problem - The curved lane changers. They will not work. Otherwise you seem good to go. So if you replace the curve lane changers with standard curves and possibly introduce more straight lane changers you will be back on track - sorry for the pun!

I doubt you will be alone. I suspect a considerable number of users of Scalextric do not use the forum and will end up here only after trying to find out what we know will not work. A little transparency is all it takes and a mention of at least the old curved lanechangers not being compatible would have been enough for users to look into it further.

That is correct subject to the lane changers having the original mod for analogue use. Of course analogue cannot use lane changing anyway. Non-modded curved changers will not work even in Analogue mode. But since you can't use the lane change at all with ARC Pro the changer needs replacing with standard curves and ideally replace with the straight changers elswhere as you mentioned. What I find a little anoying is that this issue only comes about by users trying! - I very nearly bought some curved lane changers but decided any further spend whould have to wait untll I made a decision about ARC Pro.

The mod isolates lane1 from lane 2 so analogue can work. Unfortunately it leaves the changeocer lane with mixed supplies. One rail feed from Lane 1, the other rail from Lane 2. Put a car on that with ARC Pro and it effectively shorts the two lanes

By lane switching I would qualify that means the crossover track sections not the lane changers (which do not work in Analogue mode)

You should also be aware that the old classic track has a shallower slot than the Sport Digital. So modern car guides can catch if not trimmed down.

They are incompatible with ARC Pro See https://www.scalextric.com/uk-en/forum/arc-pro-limitations-on-track-layouts/?p=1

Users of ARC Pro have found that some track layouts that worked with the older 6 car digital advanced powerbase (APB) C7042 cannot be used with ARC Pro. All of those limitations stem from the fact that the ARC Pro powerbase needs to have a layout where there are always two lanes that are powered independantly. Each of those lanes can be split to power more lanes but can never be combined back in a way that combines the powerbase lane 1 and 2 electrically. The straight lane lane changers have dead zones where the lanes cross that keep the lanes electrically seperate. - Just so you know! Curved lane changers that were modified to work when used in analogue mode will no longer work without major surgery because the mod left the change lane (not used in analogue mode) with power to each rail from different lanes. It would now need power to both rails from just one lane requiring the rails to be cut and a dead zone introduced. Pit lanes generally need to be used in the designed order but nesting i.e. two pitlane entry pieces followed by two exit pieces will not be a problem because all the pit lanes are powered from the first entry lane. Single lane chicanes on the two main lanes created by reversing the pit lane pieces will not work. Analogue Crossover tracks (Not the crossroads) must be in pairs. Power booster cables must be used strictly in the same way as you would for Analogue circuits. Any other track pieces that cannot be used with ARC Pro, please post info on them. e.g. I think Gorp may have identified a particular lap counter that cannot be used so the part No would be welcome. The only purpose of this thread to provide guidance on what scalexctric parts or arrangements will not work in ARC Pro only.

Actually Gorp I have just read through, there are plenty of posts about the C7042 APB and it starting in Basic or Pro mode but nowhere do you report the issue with ARC Pro. The curved lane changers actually work with C7042 and can work with the Analogue mode on the C7042 APB when snipped. ARC Pro is a completely different problem that so far as I can see was raised by Twigman on the 9th. Just point me to where you say you raised it.

Thank you Twigman, Reading through that thread the answer seems much simpler. ARC Pro seems to have been made with the idea of at least two lanes existing which are powered and isolated independantly. That of course makes switching to Analogue mode a piece of cake but it severely limits what you can do with Digital. Scalextric really need to list the do's and don'ts with but It means (at least the following) Curved lane changers will not work at all unless further modified by cutting into the rails on the change lane, putting in dead spots and rewiring so each half is powered from each lane. Odd number of crossover track pieces not allowed. Chicanes of two lanes into one not allowed Power boosters fitted in fixed digital layouts may need to be doubled up removing any track to track local links. Pretty much a nightmare for any of the large fixed Digital layouts, Also a nightmare for uninformed consumers who like me like to put a single crossover into a circuit. LOL bring back the goodwood chicane for digital users to have one! I still have my classic one I think with the adapters! maybe have to mod it to deepen the slot!

I don't have ARC Pro so am only passing on what I have heard. The way power is delivered to the track in digital is no longer as though the track was one big lane but is powered as two seperate lanes, the analogue way, even in digital. This means that it is impossible to have sections of single lane (where the 2 lanes merge into a single lane) and the CLC, even modded won't work as the mod picks up power from both lanes (left rail left lane, right rail right lane)......it's a phasing issue One analogue crossover in the circuit would make the layout one big single lane - what happens to your "phasing" then? Please post the source of your statement because at the moment I am not the least bit convinced.

Could one of you explain what happens in ARC Pro when you use the modded curved lane changer, assuming it has been correctly modded. Incidentally that mod is very poor unless you snip a section of the link out say 3mm to ensure the cut ends snipped don't touch again. Twigman has said the mod does not work (with ARC Pro) which I take to mean digital cars cannot run through the lane change lane. That would generate an interesting question for pure digital circuits that have a single analogue crossover!

If you read through one user did have it working with Kindle Fire but later had problems with an ARC App update. Interesting that the paper specification is OK although you should check and confirm that the Android Operating System is at least kit kat 4.4 The version of Bluetooth required is 4 which current models of the Kindle Fire have. Older models of the Kindle Fire may have Bluetooth 3 which is not good enough Also note that some users who had problems after an update seemed to resolve them by removing the ARC App and reinstallinng it fresh.

Well I am sure you are not an idiot but maybe not informed. The first thing I need to ask is, do you have digital cars on a digital layout. Be aware that ARC Air and ARC One are not digital. Neither is the older scalextric sets unless they have a digital powerbase and digital chipped cars. If for instance you put a lane change on an ARC One or ARC Air layout all that happens as you approach the lane changer is you hit the brake! - The digital controllers have two buttons on top, one for lane changing, one for braking. The Analogue controller have just the one button. If your layout is in fact digital then you probably have operation issues as Gorp has described.

I think you missed the bits in the review "Switch to Analog - there is a switch on the side of the c8235 to enable analog" A later post in the same thread goes on to say analogue works both lanes with just one power supply unlike the C7042.

Some of the questions I have about the "ARC App" are identified in this thread. However having just watched a Youtube video of the App it seems to me the App is for Air only and nothing yet for the Pro. I just don't see it working "as is" for the Pro since the information about 6 cars in a race will have to be shown in a very abreviated way to fit on the screen of a cell phone! Does anyone who uses the App know if there is a "ARC Pro" aspect to it or will it be an entirely new App.?
