fitting stay alive to 08s
« on: September 09, 2019, 08:59:43 PM »
hi

does anyone here fit stay alives to 08s?  if yes does it help much with smooth and slow speed running as well as reliabiliy?

how much would it cost to have a stay alive capacitor fitted?

cheers

John over on Youchoos has fitted them along with sound, see the guide on his site.

I found the use of a graphite pencil on the rails vastly improved running of these small shunters without the need for stay alives.

I once did a video of a class 14 taking 20 minutes to cover 12 inches, on a graphite treated track, that's good enough slow running for me.

thanks paul

my 08s are not terrible but it can be frustrating when they occasionally stall or need a push start! was just exploring options...

ive read about using graphite pencil on the track before so i'll have to try it out.

cheers

Hi

I did a thread about this about 3 years ago can't copy the link but do a search for class 08 keepalive.  Others contributed a lot of useful info
Cost was minimal and results were very good.  You need to right DCC chip which will support keepalive CT and Zimmo are ones i have used

If you are lucky enough to find one of the single sided CT decoders that are thin enough to install next to the gearbox, that would leave the gab area free for quite a large capacity Stay Alive, removing the bulkhead detail will give access to even more room.

The trouble is CT decoders have a bit of a poor reputation.

I would bring down the top of the gearbox a little and mount a Zimo MX616 on top of what's left of the box then mount the stay alive on the floor of the cab, with a small hole drilled in the firewall for the wires to the decoder, unless the firewall was removed as mentioned above for even more stay alive.

I fitted sound to all of mine using Zimo decoders and after removing the PCB from the end of the motor to remove the suppression component I never realy had any running issues over points etc.

Stay alive will not help locos that need a push start. The capacitors only stay charged for a fraction of a second, enough to get you over a dead spot, but not if the loco has stopped on one and won’t help a generally poor starting loco.

Agreed, if the loco is not a perfect runner on a flat clean track, stay alive will not help, its best to sort out the reason for the poor running before taking a hacksaw to it.

If the track is 100% flat and clean then you need to look at how clean the wheels are were they contact the track, and how clean the backs are were the pickups make contact, plus also make sure the pickups are clean and actually making contact with the backs of the wheels.  The 08 IIRC has pickups on all 6 wheels, a basic test for this can be done with a simple multimeter on low resistance mode or continuity.

Sort the loco first before doing any work.

I assume its DCC fitted as you are talking about stay alive, did it run OK on DC before conversion, if it did and its lumpy on DCC you may just need to play with the CV settings to improve and smooth its running, was the PCB removed from the motor during conversion, it should be removed as it contain suppression components that are known to upset digital decoders.

I have just fitted a Tantalum capacitor to my Farish 08 (Outside frame version). The chip is a LokPilot Micro. There is room between the front of the motor and the radiator.

To say I am pleased as an understatement. I bought four capacitors from Kevin at Coastal DCC for just a few pounds. The loco will now crawl along over points and baseboard joints on setting two with the chip set to 128 speed steps. It now runs so slowly that, to be fair, I would only run it that slow to show off  :D

My other 08 has now received the same treatment!  :claphappy: :claphappy: :claphappy: :claphappy:

I was really worried about this one as it has a tiny CT decoder that I can barely see, let alone see the solder pads.

I have to give a massive vote of thanks to Kevin (Coastal DCC). He's never going to retire on the money he gets from me but the support he has given me is invaluable.  :beers:

I was thinking about posing a video showing how slow they go but I don't want to win the "most boring video" award. Paint dries faster.

Typical. I took Southwark Bridge down this morning to make way for Southbridge which is showing at N Gauge Southeast in a few weeks time.

Never mind. Tomorrow I'll see if I can sort out a video of my 08's on my test track.

OK.
With apologies for the shaky hand held camera and dodgy lighting, here's a demo of an 08 fitted with stay alive. https://www.youtube.com/watch?v=rRkDO1eGbjo

It is entirely possible that, by playing with the cv's it may go a bit slower but this is simply what can be achieved by fitting a stay alive capacitor. There's just room for it behind the radiator. Once some tape has been put over the capacitor's terminals it's a gently push fit.

I obtained the capacitors from Kevin at Coastal DCC for a few pounds.

Excellent stuff. Runs very well over points!

Behind the front rad you say? That means I will have room in my sound fitted 08 too... which is crazy! :D
