Need Help With Bachmann HHP-8
Posted by KisNap on Wednesday, January 4, 2017 3:17 PM

Hi Everyone,

I hadn't run my N scale HHP-8 in a while and when I went to run it the other day the directional lights work, but it doesn't run.  The layout is DC and all of my other locomotives work, including a second HHP-8.  I removed the shell and there are no obvious loose wires or anything out of place.  Any ideas?  Thank you!

The N scale section of my website is now uploaded with a lot of various things.  Check it out: www.CarlettaTrains.com

I would suggest getting your voltmeter out and trouble shoot.

I am assuming you have a DC only version.

Below is the DCC version.

Split frame contruction. Power is sent to the motor where each motor contact touches the frame halves. I have a couple HO that have the split frame construction.

There should be PC board for the lighting.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.

All of the N scale HHP-8s come with DCC inistalled.  I don't currently have a voltmeter, but I suppose it's about time to get one.

I have seen in a number of forums that when a loco lights but does not run to do a decoder reset with a DCC system.

CV8, enter 8 and recycle power.

Procedure I saw in the Bachmann forums also.
