BP installation - where do what exactly to eliminate track power feed?

[rentren]

Hello on a hot BC-Kootenays day and somewhat smoke shrouded (not of steam engines, it's the forest burning across them thar mountains).
This harks back to a much older thread and a recent reference to it wrt BP/RC (DCC).

So, theory.
Remove contact behind drive wheels (coal), possibly cut power from other wired axles, and cut power from contact shoe, then bring battery leads into the positions where track power leads were. So much my attempt to conceptualize.

I'm looking at an oldie (pre-1989, made in W. Germany) Harz and/or DR 996001, i.e. LGB 2080, no sound. LGB called the 2080S a "Super-Dampflok". All but the first of my BP/RC conversions were carried out by WGRR (John at Winona Garden Rail Road). Very helpful, interesting solutions (lighting of my RhB crocodile), yet in a way I think I ought be doing it myself (particularly be cause he is loaded with requests).

The 4 pages of SERVICE sheets look impressive and leave me hesitant. So far I have not opened up the loco, invoking WGRR services seems once more the easiest way out. Perhaps the discussant in the older thread feels like doing a walk-thru for the faint of heart?

Thanks for any detailing, in particular of course with the LGB 2080 steam engine. -- Rr

Ok how to start, well first principle what are you using for RC, I think it is Crest? Below shows the Crest DCC chip, the first pic shows the terminals that interest for a start just to get a loco running. Motor is obvious, input is power from battery via a fuse and on/off plus charging socket for batteries. For this the on/off is to make toe loco live on but the clever part is that the batteries can be charged when the switch is at off using a Single Pole Changeover switch. You can buy these with a centre off but not necessary. The second pic shows how the units look when put together after of course they are wired up. Note where positive wire goes.

The loco may if it is a newer one have 4 wires on a plug. 2 are from pickups, the other 2 are the motor. The pickups can be ignored at the loco end but you do need the motor connections intact. Use a meter to work out what is what. Touching wheels then the wires will tell you what is what. Checking out the motor wires disconnected from any internal circuit board should give a reading of resistance as the motor will give this. That should get you started.

Older 3 pin locomotives need pulling apart to convert to 4 wire, there are threads about how to do this.

The set up of the TX to link the RX is a bit intense, sorry but reading the manual and followingbit is the only option there are no short cuts!
