With the engine stopped it draws 2 amps, even with tender not connected.
Have not checked continuity board is in the FEF 835 steam engine that cause the current draw?
ITEM NUMBER is 682810
Any ASC TECH would be appreciated
Thanks for any that can help find the issue

Is this before startup? And at what track voltage?
Hi well It's starting up in conventional so i only have 9 volt and shows 2 amps on z4000 transformer any help would be appreciate it hope Jon Grasson gives hi input !
Alan
Well in conventional if the smoke unit is on, 2 amps would not be unreasonable IMO. Will it run forward and back. Any sounds or lights on? If no lights at 9V on the track there may well be something wrong.
Hi Rod no offence but your wrong 2 amp would only exist if smoke unit is turned on! so I'm sure it is a engine board not in the tender, but thanks for trying really appreciated, the RCMC board is $200.00 here as the rcl board is$99.0 plus shipping!
Sincerely thanks Rod for trying

Alan,
Please remember the lower the track voltage, the higher the amps to obtain the same wattage/power. Not sure how the control boards are configured, but if they are trying to put the same power to the smoke unit, they will pull more amps from the lower voltage source (track voltage).
Do you have the capability to run in command control? If so, how many amps does it pull at 18 volts track voltage with smoke unit on and then with smoke unit off?
Also, I would carefully inspect the smoke unit and check the resistance across the elements and amp pull of the fan motor. At their correct voltage, they will not pull 2 amps. That is too much.
Hi it only pulls 2 amp if the smoke unit is set on when using remote is set on hi otherwise, barely not current at All ! I know the problem is in the engine as the tender is not connected!

Read it again; that's what I said.

Again that’s 2A at 9VAC?? That using 18W if we say we normally see around 1A with 18VAC and the smoke on again that’s 18W.
it’s just pulling out the necessary current for the provided voltage.
Maybe some base lines would be a good start.
what is normal current in your view for this locomotive and What / how are you using to measure current? Is the measurement method identical now and in the past?
Hi shout out to Jon Grasson ASC tech and Lionel service tech!

Hi Marty it tells exactly what the issues @ 9.00 volt current is 2 amps is you raise the voltage should be 18 volts the amps could go to 10 amps not willing to risk cooking boards that cost $200. you would burn up boards is that how you trouble shoot by smoking boards unnecessarily !
no offense intended just looking for every bodies input to solve my issues!
Alan
Shut everything off in engine with switches underneath. Take another reading, also take a reading with nothing on track. Than let’s us know, also turn items on one at a time, let’s see what the draw is then. Also you can raise voltage slightly and see what the amperage is, this way you may see a Plateau of the numbers. Also do you have a good meter that measures amps? If so drop it into the circuit let’s compare the numbers.

Not really. I don't see anywhere in this thread that "Jon Grayson" posted or that would have made sense. Did I miss the post?
Maybe a misunderstanding about “Shout out” as used here is happening. Maybe it’s a request for Jon’s G help vs. kodos.
Why are you looking for an MTH ASC for a Lionel Legacy locomotive?
Unplug everything but the 4-pin power/motor connector and see what the situation is. If it is drawing excessive current with just the 4-pin power/motor connector plugged in, it's almost surely the RCMC or a short in the motor brush wires to frame ground. It could also be the lousy Canon motor has a shorted brush, that's happened to a number of them for me.
If the excessive power draw goes away with only the power/motor connector plugged in, it's likely a short to the frame somewhere else in the wiring. Find the short and you'll likely solve the problem.
Hi i was trying to get Jon Grasson as he is a Lionel repair tech I went to MTH tech school and he helped during school that's how i met him , i would have chimed in earlier but i thought you would have had some advice to help me. did you ever get the Lionel test rig ready !
sincerely Thanks Alan
Not only did I finish the test rig, but I also added the capability to test the latest Lionel LCP2, LCP3, and Lionchief Plus 2.0 boards.

My apologies. It sounded to me, that he gave you a solution. A good way of drawing attention to your post is to use the "@" with the members handle and they will get an alert. Without it they won't know to look for your request if they are not following this thread. example @Alan Mancus .
