Well it finally happened, my old girl finally got up and left.
Didn't make a sound, didn't make a stink. Just left in the middle of the night. We've been together for so long I forgot when I got her home and unwrapped her & eyeballed her charms for the first time. She was a true champ even though I kept her under the table for most of her life. But she enjoyed the scenery. Never complained. Just hung out and performed her duties faithfully. Every time I wanted something she would turn on instantly. Zero to sixty in a flash. Occasionally I'd take her out and clean her up. Put her on the bench upside down and checked her out.

But now my dilemma. Do I open her up, do an autopsy. Or just let her go and rest in peace?

My girl---- Hitachi M12V.

Does anyone remember bypassing their speed control? I have white in from the switch, black out to a crimp terminal that joins a white, and a thin yellow that goes to the switch. So my guess is that the yellow goes away and the white in goes to the crimped white.

pop the speed control knob off then underneath, in the potted unit, there is a small variable resistor. The common problem with these gadgets is that the wipers don't make good contact with the resistive arc-strip they swipe around. Pressing on them usually diagnoses this - it works or stops working etc. Lo and behold, pressure on the VR may cure the problem. place a couple of tiny rubber washers on the face of the VR so that they come between the circular knob and the VR - padding, if you like. When you press the control knob back on, the VR is now under a little pressure. it may start working again...

plan ''B''...

the small yellow wire is a feedback wire into the controller and doesn't need to be hooked back up to anything. The wire from the switch goes directly to the wire from the motor.

I forgot to mention---the old girl trips the circuit breaker upon startup. the motor spins for a millisecond then the breaker trips. But no smell whatsoever.

@ stick pressing/turning/cursing at the yellow wheel (potentiometer) doesn't help. So I guess plan B is the go-to operation.

After thought!!! How about a shot of contact cleaner on/into the pot to dissolve any carbon. Guess It can't hurt & I am talking contact cleaner here---not canned air.
I remembered all the warning you gave me about that stuff!

She served me well!!

Got 2 of 'em one brand new still in the box & a used one.
I put the used one in the table but for whatever reason, I couldn't route a straight groove(!?!?) so I took it out & put in a PC693.

Will be looking @ the Bosch's problem, or mine, sometime this week

I have the trim Bosch, and while it's nice, I think I like my DeWalt better. (Of course, all my routers are trim routers now, since full-size is too cumbersome with my sign making.)

The comments I could make on the opening post, I'll try and remain lady-like and keep quiet.... (for now) :lol: but oh, the comments I could make...

Check the brushes. Open it up and check out the cord with an ohm meter. Cords go bad next to the tool and at the plug end.
he has all of the trouble shooting PDF's...

New member M00sie had his two quit because of the speed control. He opted to move forward to something newer. I checked to see if there any critical parts I might need besides the speed control and it, the armature, and the plunge base are the only 3 items you can't still get. Even collets are available. If the speed control goes on mine I'll probably just bypass it. I took the V model out of my table when I got my V2 model. It is way better for table use.

Autopsy!#1 Check the brushes.
#2 Open it up and check out the cord with an ohm meter. Cords go bad next to the tool and at the plug end.
#3....or write a country 'my wife left me and my router died' kinda song.

#1 Did that first off. They appear to be ok, about 1" in length IIRC
#2 Didn't think of that. Will look into it
#3 Not a big fan of C&W music. I can tolerate it for about 1/2 hr @ a clip. I can usually tolerate OLD cowboy music better. Just shows how old I really am. Alsp, I'm laying off commenting on the title proposed in lieu of self preservation.
