The mogul still doesn’t work. Could it have blown a fuse somewhere? The fuse in the radio control is fine but there’s no power to the mogul or sound. It quit when it hit a rock a ground squirrel left it on the tracks and with my poor eyesight didn’t see it.
A second question. The headlight was not wired when the rc/battery was installed. Is that something I could tackle?
Ah, wait.
The biggest failure in those Moguls is the cable.
The wires break right at the plug.
Insulation stays, but the wire inside breaks.
I have to fix them all the time.
Easy to do if you’re careful. You have to take the plug apart, observing proper orientation of all the “bits”, dig out the insulation, trim the wires back 1/4", re-insert and crimp together.
What kind of radio gear?
The stuff I use has battery voltage out.
The Mogul has 5V bulbs.
I put 14V GOW bulbs in my conversions.
You will need to find out what output your lighting circuitry has, and put the proper bulb in.
If the radio gear is in the tender, and the loco won’t run but everything else does, most likely the wires.
Have you dropped the chassis and applied power directly to the outer pins of the motor block with the tender unplugged to make sure the motor works?
Thanks Dave. I have one more question for you. Can I check the motor with leads from a 12-volt rv battery or is it too high in amps?
You can use that battery.
Or, if the pins are still sticking up out of the block, just put a good 9V battery across the pins.
All you need right now is to see if the motor works.
How well the chassis functions we can deal with later.
Both the new and old motor blocks work fine. Just so you know, when Mike installed the Instant RC and batteries he went around a lot of the LGB stuff and it has a trailing car with sound in the tender. It originally had Sierra sound but it was in conflict with the Instant RC so Mike installed Phoenix sound and it never skipped a beat until it hit that rock! What’s the next step?
Well, next is to find out if the Instant RC is working.
Chuck has retired, and the are “potted”, making them unrepairable.
Find the motor output screws on the throotle.
Connect a voltmeter or an old motor to them, power up, throttle up, and see what you have.
If it works there, and not at the motor block, the problem most likely is the plug.
Guess what? The motor worked! Now we’ll see if a legally blind guy can fix mini plugs! The RC unit is in a trailing car so I have three plugs to play with! I know its somewhere in the power because the Phoenix Sound doesn’t work either. Thanks Dave,
Whatsa “throotle”.
Secret U-boat code?

Whatsa "throotle". Secret U-boat code? :) :)
