Some joy at last

Hi all!

As mentioned on previous occasions, have a lot of old (30/40 years) Lima H0 rolling stock incompatible with my modern locomotives because of a difference in coupling height. I also have two old Lima H0 locomotives which I had previously unsuccessfully tried to digitize (one was returned to the analogue state and the other is still disassembled). I have read a lot of forum entries on remotoring Lima locos, with the differing opinions and recurrent comments and, in view of the complications and no definitive opinion in either way, I have decided against the idea. Since in the meantime I had managed to digitize a 39-year old Wrenn diecast loco, after unsuccessful attempts, with the aid of an expensive Zimo decoder (MX632), this led me to the conclusion that my previous attempts at digitization had failed because I was using cheap inadequate decoders of insufficient capacity, although the capacity of the Zimo decoder may be in excess of what is really needed.

I can now say that I have successfully digitized the above indicated disassembled Lima locomotive (CC40101) with an MX632 decoder, as above. It had its ups and downs. After wiring up only the motor, I put the loco on the programming track and all I got was “no loco”, “error”, “short”. A visual inspection showed that I had all the insulated wheels of both bogies on the same side, so I removed the non-powered bogie and turned the wheels round, but got the same results. Finally my son-in-law tested it with multimeter and discovered that one of the axles on the non-powered bogie was the wrong way round. Once this situation was corrected I started to get correct readings from the programming track, but the references to right and left sides didn’t seem to coincide. Finally it dawned on me that since I had dismantled both bogies to the extent of removing the pickup strips to clean them, I had inadvertently reassembled the power bogie the wrong way round. Anyway, to avoid dismantling the power bogie again, I swapped the grey and orange wires over and then connected the rest of the wires accordingly. The locomotive now runs well and the next thing to do is to tweak the CVs appropriately to get the best results from this decoder.
