Kline Problem

Do both units have its own K-Line Cruise board? This is unlike K-Line which typically uses one motor driver to drive 4 motors. To answer your question if both units have K-Line Cruise I doubt ERR Cruise will work with the good one. They have different speed curves.

I'd put a CC-M in each of them if they're independent.

Hi Pete,

Yes,  they both have Kline cruise boards.  The secondary A unit is tethered to the primary for data signal I believe.  I don’t see a r2lc in the secondary A unit.  I prop both units up on a small block of wood,  connect the tether and the primary A sputters while the secondary A runs smoothly.  If I disconnect the tether, the secondary A will stop running.

Thanks John!

I just wanted to make sure before I place my order for 2 CC M boards.  If I didn’t necessarily have to get two boards,  I wasn’t until the secondary board played out.  As Pete suggested,  the ERR cruise M and Kline probably would play well together anyway.  

Two Cruise Ms is best but you could try powering the four motors off the good K-Line board. Thats how K-Line did it with most of their F3s. Thats how my NYC F3s are wired.

Thanks Pete!

I may take a look at that option and see if that’s within my skill set.

I have the reading version and when my board failed, I converted to DCS (master and slave). To retain TMCC, I would go with two ERR boards and MU the units.

Thank you sir!

I think you may need a Cruise M for the lead unit, and a Cruise Commander for the trailing (tethered) unit.

That's what I did with my K-Line SP F-7 AAs (K-25881).

Professor, I have used a single R2LC to drive two Cruise Ms in my K-Line AA E6s. Wiring was involved though and maybe not for the faint of heart as both the serial data line and direction lines had to be fed through the tether to the second Cruise M. Works great though and no buffering was required for any of the signals.

Pete

That would work, but with a regular Cruise Commander in the trailing unit you can get rid of the tethers altogether.  

I guess the question is whether that’s worth the extra $30 for a Cruise Commander over a second Cruise M.

I upgrade a KL F-3 AA and it had the two cruise boards but different revs, and the trail was wired to signals from the lead unit.  So it was not 4 motors off one board.  G

I'd go with the full Cruise Commander and dispense with the tether.  This also allows you to run them truly independently if desired, or a different configuration.

Fellas,  this is this innards if these Kline units.  Both are powered with the primary A unit having the whole TMCC guts installed.  The secondary A unit is powered, but only uses a cruise command board and smoke unit.  It pulls its instructions from the primary unit with the R2LC board.  My question to you professionals is this.  Is this wiring harness a genuine Kline tether or has this thing been gerry rigged?  

Thanks,

Blake

That looks like a pretty standard K-Line wiring harness.  That sucker is sure packed!

The tether certainly looks professional. If it wasn't K-Line, then it was done by someone who knows what he is doing. If the wireing is already done to drive both motor drivers from a single R2LC then you could in fact replace both k-Line boards with Cruise Ms. 

Pete

Ok and thanks guys!

Blake

OK, so I pulled a KLine cruise board out of a K3304-1523CC ACL Pacific steamer.   I installed a cruise commander M steam kit.  It runs beautifully,  but there is one issue that I hope is minor.  When running forward,  the rear tender light comes on, but when running in reverse,  it goes out.  

Can someone give a suggestion on what needs to be checked?  This was installed just like the instructions said.

Thanks,

Blake

The Cruise M itself doesn't control lights. Its the R2/4LC. Did you reset the feature code? In program mode, after setting engine ID, Set, hit the AUX1 key followed by 4. Then go back to run mode.

One other thought. Did this engine have K-Line Cruise? Does the engine now start out in reverse? If so you have to reverse the wires to the motor. For some reason K-Line Cruise runs with opposite polarity of most other TMCC engines.
