I was so excited to pick up this morning my first example of the new MTH Heavy Pacifics, the U.S. ARMY version 20-3812-1

Unboxing was great, the details were perfect. So then I threw it on the track and added to DCS and first thing the headlight wasn't working. I went through a reset process and still no headlight. Class lamps and markers on the tender worked, cab light, firebox glow, just no headlight.

Found out why- connector pinout reversed on the wiring harness.

Yes, the connectors are keyed, the factory just screwed up! :D
FWIW, normally you have to crimp new pins on those Molex connectors to pull them out. However, I've been very successful at just compressing the tab enough to pull the pin out and then using an X-acto knife to pull the pin back up.

All I'm saying is, at least I'm capable of fixing it and saved the dealer return shipping and so forth. There are tons of people who would have flipped out (not saying they are wrong) over a $1200 engine that arrived with a non working headlight, and yes, it was a factory screwup.

My purpose for posting was just so that if someone else gets the engine and has the same problem- it could be a relatively simple fix.

If I didn't post, then I'm masking the problem from any public scrutiny and again, maybe others have the same problem.
Hoping not and this was just the one bad one.

Some basic repair skills are often needed with today’s models. It seems required now and then, even with brand new stuff, if you want to avoid the warranty/return shipping situation.

I collect airsoft guns and they almost always have some minor issue when they are purchased new. This is due mainly to shaky quality control coupled with the predominantly “through the mail” sales, where dealers usually don’t pre test the goods they sell. Most airsofters develop the skills to repair and maintain their hardware. Unfortunately, it is part of the hobby…

I pop those pins out pretty frequently. I didn't realize I wasn't supposed to be able to do that. I just use a really small jeweler's screwdriver.

According to Molex, you're supposed to punch the tab into the contact and then the contact slides right out. It is a bit trickier to punch it down enough to slide it out, but not too much that you can't pick it back up. Of course, Molex would love for you to buy their $500 crimp tool and more contacts, so that kinda' makes sense. :p:p

OK, yesterday was unhappy, today this is getting old quick. What are the odds of 2 engines with light problems from 2 different dealers?
The class lamp was out on the Rock Island version when I picked it up from UPS this morning.

Luckily yet another part I had in stock spares of.
Fixed it now too

Well, in the case of the Rock Island unit, the factory was probably shooting for prototypical accuracy. :p

So keep in mind, I emailed the dealer and MTH on day one with the Army version failure. A copy past of the exact pictures and details of the failure. Nothing more than the facts. Didn't say anything derogatory or anything. Then when I got the second failure, replied to the same email topic so that both failures are in the email chain.
Day 1 no rejections
Day2 (how to know you've definitely made someone unhappy)

Your message to m*****[email protected]ilking.com has been blocked. See technical details below for more information.
The response from the remote server was:
: Client host rejected: The sender's mail server is blocked by this recipient​

My takeaway is, Mike Wolf doesn't want to deal with customers- let alone dealers- let alone quality control issues.
That's fine, but nobody, neither dealer, nor MTH with a response.

Again, how to know the message was heard loud and clear? When they block your email- they got the message.

Also, I found a new problem too in both engines.
When running the PFA, the very last part of the sequence (departure) there is a loud beep or noise in the sound file.
My intent is just to reflash the sound files hoping that resolves it.'
They are different files and sounds, the Army one is a hospital train, the Rock Island is also passenger announcements but different.
Again, both had the noise and I ran several times to validate it was not a fluke.
