TAS SAW BOARD

This looks like an EOB board. Its not a direct replacement. Download the manual located at the first page of this forum. Bottom sticky. To use this you will also need a tach sensor.

You would need to download the complete installation manual, which includes a lot of adjustments done with a Cab1 remote and the original TMCC command base.

Best wishes with your project.

I'd also bench test this before you spend the time to wire it into a locomotive.

In looking at the TAS files I see that there are two EOB CRUISE CONTROL install manuals and a file that shows only the pin out diagram without the install instructions.   The pin out diagram for the install manuals differ on the AC input from the file showing only the pin out diagram.  It says not to connect to the two pin Power Input plug but rather to connect directly to the AC inputs on the Bridge Rectifier,  where as the complete manuals show connecting to the Power Input plug.  Can someone set me straight on this ?  Just a guess, the traces on the Power Input plug are not large enough to carry the potential load and connecting directly to the bridge rectifier solves that problem.  Thanks in advance.  J

John, TAS recommended connecting directly to the bridge rectifier in later documentation, apparently at times the current cooked the traces between the power connection and the bridge.  Your observation was spot-on.

Johnaction, looking at your photos of the circuit board, it looks like you have a capacitor that is swollen and leaking. If it is, I would replace it before you fire it up. Hope I'm wrong and it's just an illusion.

Looks like it to me too.

Right you are Dave, that one is a goner!

 Swollen cap,   I ordered 20 ea of all Ecaps on the board just after I took it from the box.  Seller claimed loco it came from was fully functional.  The bottom of the board has "2002 Lightning Systems" on it, puts it right in the middle of the Ecap pox.  Perhaps I can come up with more EOB boards with swollen caps.

   Also, anyone on the forum have a couple of TAS UCUB boards they would part with ?   J

I have several I be willing to let go email me at gpamikeh1@yahoo.com

I have a couple of EOB boards, and a SAW board, but no UCUB boards.
