Hi,
I got an MTH M&M's F3 Loco today from eBay seller... looks just like my previously purchased M&M's non-PS2 unit that was part of the original RTR set.
Put it on track... power on, typical power up, PS2-like sounds. Everything works well! but,
Some strange things I can't figure out:
1) there are 2 headlights. The seller said "one headlight doesn't work"... so I looked. The top headlight is off, but... the bottom headlight looks like a MARS light, (not really MARS, but) slowly fades up and down - looks great! But no mention of this in any advertising.
2) On the bottom, there are the usual 3V charging port and a volume control, but... there's a switch on the bottom in a spot where a switch is supposed to be. ON-OFF stamped into chassis. No idea what it does, but everything works right so I really don't want to turn it off! (whatever it is)... not a smoke switch - there's no port for smoke on top.
Seller didn't include instruction book, but in the online manual there is no mention of switch or fancy headlight!
My Locosound version (30-4190-0) of the loco has the same hole for the switch but nothing in the hole.
Any thoughts? ... or someone who has this loco (part of set 30-4190-1)
Thanks in advance,
Ed
This can be that it needs a new small unit I think is called the FET. My FET kept failing, so the boards had to be pulled off and a shorted out wire was found which was caused during assembly by a screw.
