ARC PRO simple mod to switch the lap sensor into APB-mode

This simple modification switches the lap counting sensor of the ARC PRO into an APB-compatible mode.

The modification relaxes the ID-LED-to-guide-blade constraints of the ARC PRO enabling cars with surechange guides and/or cars with ID LEDs placed a long way back from the guide blade, still, to function correctly. This is achieved by switching the lap counting dual sensor into an APB-compatibility mode.

In making this modification, the analog lap counting function is lost.

The modification is straight forward... and done carefully can be reversed if necessary.

The modification is for DIGITAL use only.

The following nine photos show the procedure (no text)...

Any feedback on whether this mod is liked or not, and whether it does what it says on the can, would definitely help in due course please. Ive been using the mod for about six months with no issues whatsoever. Hopefully others will enjoy a similar experience

I will be doing this mod Doc, but it will be once the airport opens up again...not willing to risk messing something up (even by accident) and then not be able to get a replacement PB until the end of June

Hi Doc, as I said earlier I will do this mod, but not until they reopen the airports here...when I do the mod I'll likely just cut the grey wire and put a switch in there that will be accessible thru the side of the track...I've got loads of the small switches that came out of my Carrera cars that were used to switch polarity
