How to install sdh164d in kato ef510

[Edwardchris]

Im new for dcc and I can only found a little information about how to modify the circuit board . Hope u guys can help thx.

That's an HO loco?  I don't have experience, but my Google-fu is strong.  I found this video of someone installing one:

 

 

I wouldn't call it simple, there was a fair bit of milling of frames and the body, and soldering. But the video seems to provide a good guide to what's involved.

Thx . But I just can't see the wire connection on the led board . Want to have a led connection picture . Thx a lot!!!

[KenS]

If you can post pictures of the light board, I'm sure someone can point out where to cut traces and where to solder wires.  We've had discussions like that for other trains in the past.

ok thx anyone can help?

and the back

Someone else might have a better way to do this.  What the person in the video appears to have done is remove the entire outer edge of both sides of the lightboard, leaving room for wires while also removing the traces that run along the edges that he identified as "anode" in the video (compare the sides of the attached snippet from his video to your board).  Then he soldered a bunch of red wires to one side of the LEDs (the positive or "anode" side) and connected them all to the decoder's blue wire (decoder positive), and connected function outputs (decoder negative) to the other wires, and soldered them individually to cathodes of the LEDs.

 

It's not as clean as cutting traces on the board and soldering a few control wires to those, but the board looks like it might be a multi-layer board, in which case some of the traces may be hidden away between the layers and inaccessible for that kind of approach.

 

There isn't enough detail in his video to identify which side of each LED is the anode though.  You might be able to do it by tracing those silver leads, except that to me it looks like some are anode and some are cathode.  I'm not very good at doing this from photos though, so I can't be sure.

or can i follow the pic from the topic below.(esu decorder into ef510)

[Edwardchris]

i found this one is clear and easy for me

is it same with install the sdh164d?

[KenS]

Assuming I'm reading the manual for the Loksound 4 shown there correctly, and I think I am, the photo you cited (from here) shows the lightboard wired to a Loksound 4 as follows (all standard colors, same as on the sdh164d):

 

Black - left track

Red (looks orange in photo but orange goes to motor, not here and position is right for red) - right track

White - headlight

Yellow - rear headlight (tail light)

Green - AUX1

Blue - common (+)

 

he's also cut three traces, to isolate the black and red inputs (black cut twice, between black and yellow and between yellow and green).  Those wires all connect to places that make sense to me, although without holding one in my hand I'm hesitant to say I'm certain it's correct (for all I know the next step after that photo was the board exploding, although from that thread I expect it worked).

 

There may also be a cut in the black area at the far right, below the LED with the white wire, although I'm not clear why.

 

So it has the usual reversible head/tail functions plus one AUX function wired.  I'm not sure what the AUX does though. I  would expect an SDH164D wired the same way to work.  It is possible he had to cut or isolate something else, so if you aren't experienced in decoder installs, it may be worth your time to provide the photos and info to a professional decoder installer and have them do it. I'm really confused by the green AUX1 wire though, which makes me nervous.

ok i also need time to think about how to do it thx alot

[Edwardchris]

ok thx for reminding
