Hi group,

I'm trying to upgrade a loco (steamer 3310) from a 6090 to a lokpilotV4 (in DCC mode).

I've got spare parts for two-pins bulb holders; Fine!

Now the problem is with the smoke generator. The fact is the return signal (ground) of the smoke generator use the loco chassis.

In the LPV4 manual, it is stated that you can:
-either use the common ground (chassis) with front & rear bulbs, and also use the same common ground for AUX1/AUX2, i.e. without using the blue wire. But in that case, you suffer from light flickering (which I'd like to avoid, and that's the reason why I've got 2-pins bulb holders)
-or use the blue wire as a general return signal for front and rear bulbs, and AUX1/AUX2. In that case, the smoke generator (AUX1) must be insulated from the chassis (yes, but how? )

My question :
Is it possible to wire the return signal for F&R bulbs with the blue one, and for the AUX1 -smoke generator- with the chassis (i.e. the black one) ?
The wiring schema will be :
-front bulb: white & blue;
-rear bulb : yellow & blue;
-smoke generator: green and "chassis"

Sorry is that seems obvious for some of you, but it's not very clear in my mind.

The smoke generator I plan to use is a Seuthe 11.

Your inputs will be greatly appreciated, as usual.

Hi,

Thank you John . I'm a bit more confident as I won't fry the decoder.

I've also read in the doc I need to adjust some CV about the smoke generator. Unhappily I don't have lokprogrammer neither an Ecos, but I should succeed with my CS2 (even if less comfortable).

I'll post the results in this thread (and maybe questions regarding CV adjustment if needed).

Cheers

Hi!
It's OK to use the chassis for the ground (correct smoke generator would be Seuthe No. 10 then).
