Wiring Diagram Needed

Paul, when was that made?

Does this help?

If I remember correctly the tether has to bring over serial data for RS, Coupler signal for tender, reverse light.  The 4th wire may be AC center rail.

I would plug tether into engine with shell off and trace with continuity meter.  Find which is rear coupler, reverse light, serial data and test other until you get continuity.  Mother boards should have print on them what they are to help.  G

I believe it was 98 or 99, maybe as late as 2000?  I'm not at the computer with my spreadsheet right now to check when I acquired it.

Many of the motherboards don't have any printed pin nomenclature, though that is appreciated on those that do.

Thanks for your interest and suggestions.  Pictures attached will answer some questions.

John, I see more mother board with it, than without.  Even TAS had it.

Paul that is probably standard 28000 series wiring.  You can get it off of LIO Service website.

Red looks AC power, but from right to left I think black is Serial data, green is coupler or light so trace it, the 3 pin is ac ground sent over to tender and the 4 is coupler or light.  Not sure why that cap is between black and ground on engine though.

The instructions I posted will work for you.  There are jumpers to move.   G

G  --  The black wires seem to be for the chuff switch, one black wire goes from the engine frame to one side of the switch, the other comes from the switch to the tether connection, with the small cap between the black wires.

Paul, GO to Lionel Service manuals and call up supplement S44.  S44:3-5 and 4-1 and 4-2 have the wiring.  Your going to have to trace wires.  But the Lionel parts diagram shows that your engine has markings on Mother board so that should help.  G

Thanks G

Have the diagrams I need, looks like what I have on the bench.

Will advise on email the outcome, might need some boards.
