Hello all.
Working on installing a Revolution with a non plug & play adapter board into an older Aristo U-25. It is the adapter with the 2 fuses and larger screw terminals on it. I have wired it up as recommended, but when I apply power after a few seconds it keeps telling me its overloading, meanwhile no movement from the trucks. checked all the fuses and all is fine. Any recommendations? Is there more than one way to run wires to this board?
Thanks
Does the locomotive usually run well with track power?
Yep, so does the new block I tried after that.
Make sure you just try the motor blocks with all else disconnected to be sure what is overloading the board.
thats the funny thing Dan, I have removed the other stuff and am just running the motor leads to the revo.
Did you try just one truck at a time?
Is power from a battery with rails disconnected or are you doing track power.
On many motor blocks, the wires need reversing from the front truck to the rear truck. USA needs this, LGB does not.
Not sure about Aristo but it is one thing I would check if power is from the rails.
Didnt think of that Dan, thanks. I am doing strictly battery on this one. When doing my test I only hooked one truck up to the revo. Last night I tried it again and said overload, but when I switched direction it ran fine, but nothing going the other way. I think part of the revo board might be fried 
I wired it in last night with both trucks and same result, runs fine one way, but going no where fast the other way lol
Aaron, We (Jim & I) had a problem with sound revolutions, in a GP-38… Tried 4 sound revolutions, none would link… Sent them all to Navin, and all checked out fine…
When we got them back, they still would not link… I had a Non-sound Revolution on hand, and we tried that, and it worked as advertised… Seems the pin connector section had some wrong with it, and it wouldn’t work with the sound revolutions, but would work with the non- sound ones…
Any problem we’ve had with ““Overload””, was all caused by a pinched wire, when the shell was put back together…
Don’t know if any of this helps, but, there it is…
If working in only one direction, the cause can be either a bad receiver board, or one motor lead is still tied to 1 track lead.
And this can case the board to be bad.
When first installing a decoder I always use a 30 ohm resistor in series with my power source to verify simple operations, and until all works properly I keep this resistor in place.
