I fried one of my PS2 boards recently, and after spending several hours going through the wiring with a fine tooth comb, I found a tiny point where the smoke switch wire was grounding against the chassis from time to time when the motor trucks would turn in just the right place. Sucks that I didn't find that and destroyed a board, but oh well.
I put in a replacement PS2 3 volt board after I fixed the wire problem, but the replacement board is for a gp40. Obviously that's not an aba configuration. The engine is a Santa Fe e6 ABA with the slave board. Is it safe to plug in the slave board harness while the GP program is running in the PS2 card? Or does the ABA configuration depend on having the proper program in the ps2?
I have a programming track at my house, but of course where I'm doing the work is it a different location and I would like to be able to test it out.
