This question is a follow-up to a question I asked GR John but anyone can feel free to chime in with their experience or wisdom.
Previously, we discussed adding an ERR Cruise M to a K-line PA-1 AA all powered unit. You mentioned that the cruise does not like four motors.
While a little more expensive, (actually twice the cost plus), I am considering adding Cruise Commander to the rear unit and eliminating the tether and running as an MU train. hopefully with the "nudge" they will run smoothly. I also have an older conventional K-line FA ABA that I am upgrading with a single non cruise board.
Cruise is not as important because I have done similar with the K-line MP-15 and S-2 and have gotten good slow speed running after rewiring the DC cans (without flywheels) in series after setting the stall speed and high voltage limit.
My question is: since I will be running 4 DC cans, is it preferable to run them all in series? All in parallel? or two sets in series that are then connected in parallel?
And why of course?
off the topic, but I was breaking in my FA set on my recently acquired Crest test rollers and after a short burst of high speed running, noticeable heat/smoke was coming from my conventional E-unit. I would not expect this normally, especially with no consist. But what I think was smoking are triacs but the do not have heat sinks attached to them. Will not mater after I convert to TMCC but I want to use the e-unit on another build using an old open frame All nation DC motor. If I fabricate heat sinks, will it help and should I use aluminum or steel?
Thanks
