PS3 diesel board, smoke unit circuit failure.

Lou1985OGR Forum Member

I've got a PS1 diesel sitting here that was upgraded with a MTH PS3 diesel kit that has an issue. The person who installed the kit neglected to put the smoke elements in parallel before it was powered up. So now, if the smoke unit is hooked up, the fan constantly runs with power applied and the locomotive can't be found by the TIU. If the smoke unit (both the resistors and fan) is unplugged the locomotive will operate fine under DCS. So my question is what got fried on the board and is it repairable? If not I'll have to tell the guy the board needs to be replaced to get the smoke function back. The smoke unit needs to be corrected to work with the board either way, but that's an easy fix.
