Hi:

I have a AHM GG! with that vertical motor. Installed a DH163 decoder in it,

but could not get the motor to run. The programmer sees it and I'm able to

program, but motor would not run. Anyone have any ideas about this?

Does this run on regular DC power? If it does, it's probably a poor

runner. Basically you're looking at an old, old crappy motor.

You'll likely need to remotor to get any decent running characteristics.

According to the instructions (yea, who reads instructions) the DH163

decoders shut down when they detect a short in the motor or mechanism.

However, if that is the case you still should be able to control the

headlights assuming you installed them. Try the lights and if they work then

assume it is the crappy motor as suggested in another post.

Have not hooked up the lights but this loco was a GOOD runner in its DC

days. Remotoring will be a big problem for me since it's mounted vertically

meshing with the gears at the bottom of the frame. Have to put it on the

back burner until I develope some expertise in this area. Thanks for all

you input.

Did you test the stall current, maybe it's just a juice hog?

This is probably not an appropriate answer but you might want to start a

saving account for the new Broadway Limited GG1. See their site and listen

to the sound, use the DH163 for something else and sell the AHM engine at

the local flea market.

Hmmm, when you throttle up do you feel the motor vibrate a little, like it's trying to run? If yes perhaps a good cleaning of the pickups and mechanism might help.

If no, check your wiring for a short or bad connection somewhere.

No nothing, does not move at all. But it runs fine on DC. Has real metal

Bill,

Have you made sure the motor is isolated from the frame? Most of the

older engines used the frame for one side of the electrical path. Isolating

it is not always easy though I am not familiar with the GG1 (Other than the

real thing, man those things could creep up on you!)

#53152 Jan 22, 2003

Bill,

I have seen several replies to your problem.

I had a similar problem with a brass steam locomotive DCC installation using a DH163. The original open frame style motor ran OK on DC, and a stall test showed a little over 1 amp stall current.

After placing the decoder in the locomotive, it would not move. I removed the decoder and tested it using a 100 Ohm resistive load, and it worked fine. Guessing that the decoder was going into short ciruit protection shutdown, I decided to remotor the locomotive with a Canon can motor. Apparently that old open frame motor presented such a heavy load on start-up that the decoder saw it as a short. The Canon can motor ran fine with the same decoder.

You have already indicated that a motor replacement is not what you want to do, so why not try one of the earlier series of decoder that may not have the same short circuit protection algorithm in it. Do you have one of the DH142 series decoder available? Just a guess here, and I'm assuming that you DID isolate the motor from the frame.

Larry:

Removed the motor from the loco frame and measured Stall current of about .5

amp although it jumped to 1 amp on occasion. I did get the decoder to run

the motor, so all is not lost. I think I should try some new brushes and

some Conducta Lube and see what happens. Thanks for your help.

I have no idea which drive you have in that GG-1 AHM used several versions,

including one that used the motor case as one of the track pickup. make

sure the decoder, track, motor is isolated.

#53196 Jan 22, 2003

I have several AHM GG1s and ended up using a 3 or 5 amp decoder made for O

scale. Sorry, I forget which. I found that AHM had several models from more

than one manufacturer. Some with two vertical motors. One with a horizontal

motor and spring coupling.

Frankly, this old model is a lot of trouble. I had painted my GG1 for my

own railroad, so I wanted to keep it running. I ended up switching to a

horizontal motor frame, onto which I put my painted shell.

In an effort to smooth out jerky operation and reduce excessive top speed,

I added a lot of weight. I used sheet lead and was able to put in almost 2

pounds. I also programmed the speed curve in the decoder to be very flat. I

assigned 2 or 3 steps in the speed curve to the same output.

#53207 Jan 22, 2003

Slowly but surely this message is migrating to HO chat group, but, I found

out today that the brushes on that old AHM motor are completely gone. They

used a fine wire mesh and wraped the carbon (stick?) around it. There is no

carbon left. So off I went to my local rr store and all they had were

Athearn brushes which are much too big in diameter to fit into the AHM brush

holder. They suggested I file it down using a oo grit sand paper. Sound

like tedious and unsuccessful work, but I shall try this.

But does anyone know how to acquire, modify, or create brushes for specific

motors? I'm told that Walthers owns Rivarossi guarantee and parts for all

equipment. We shall see about that. Anyhow any helpful hints in this

matter would be greatly appreciated.

Marshall, you said you ended up switching to a that horizontal motor frame.

Where can I get one of these????

Bill,

The old Rivarossi motors do employ two different kind of brushes in a set.

The one is a carbon brush while the other is a roll of fine brass wire mesh.

I guess the idea in this is that the set supposed to be self cleaning?

I assume since Walthers now does the distribution of Rivarossi you should be

able to get spare sets from them
