Now I am not only bewildered, I am confused. USed to be simple: One upgrade kit for steam, one for diesel, and a third, available only for techs, to replace 5-volt boards.
Now it seems there are:
1. PS3 with connectors to replace PS2 5-volt boards ("3/2") techs only. Will fit in steam locos that had boards in loco
2. PS3 with connectors to replace PS2 3-volt boards, techs only and not yet available.
3. PS3 steam upgrade kit with complete wiring, anyone can buy. Has one board in tender and one in loco.
4. PS3 diesel upgrade kit with complete wiring, anyone can buy. Not yet available.
1 & 2 are the same boards but with different plug-in boards on top,
Am I correct, or still befuddled?
RJR, The PS-3 upgrade kit only has one PS-32 board for the tender. No board in the engine.
I don't think MTH will say the PS-32 can always go in the engine. Since only PS-2 5V had boards in the engine, the repair might require an upgrade like kit to put the board in the tender.
Frankly this has always been this way as far as boards. AE-10/11 and 15/16 tech only (at higher cost), even though you could buy upgrade kit with AE-10/11 in it. G
