No COP operation. No Car lon. Any ideas where to start. Replaced CPCB, noticed the problem was there before that, reason for the board was no DOL to controller. That solved that.

I believe this is an early version of a Miprom SL. If so you need a service tool to work on it. These are rare birds, they run great, but if you have an issue you need to be able to communicate with the controller via the tool.

Replaced LCECOB got car LON. john jay: early version of Mipron HS. Yes they do run great. By the way when the CPCB was replaced, one of the solid state relays was bad. Those affect ULU,ZLU,DLU. So if you have good ones from old board, worth keeping. Thanks for the help.
