The installation is for HO Scale Bachmann HHP-8. It uses TCS T1 digital decoder and was performed by Ernie's Engines, of Taunton, Massachusetts
Important Soldering Tip:
Please do not use any flux either liquid or paste on the mother board. It will damage it. Use only Rosin core solder approved for electronics use.
We recommend to use only Kester "44" rosin core, SN63PB37, .015" diameter, part number 24-6337-0007.
This can be ordered from Techni-Tool under Techni-Tool part number 488SO157 http://www.techni-tool.com
1. Remove the cover between the pantographs
2. Remove the two little jumpers in the DCC plug
3. Using a short harness install the T1 decoder as in the picture. An MC2
decoder with a short harness would also fit nicely.
Slow speed performance was good so it wasn't necessary to cut a capacitor
lead as on other Bachmann loco's.
Other solder tips:
When stripping wire, only strip a tiny little bit of the insulation. Strip no more then a 1/64 of an inch. When the wire gets tinned with solder the insulation will shrink back more. Try to not expose any more wire then half the length of the solder pad at most. In no case should solder or exposed wire wire ever be outside the boundary of the the solder pad you are attaching a wire to.
