Millermatic 135 Control PCB Schematic

[hemi-1]

Hello, new to the forum. I need a control board schematic for a Millermatic 135 (Serial#LE222177) part #207463, to diagnose a feed motor issue and just to have the schematic. Any help appreciated.

Have you tried calling Miller tech support? They may be willing to give you one on a machine that old.

Welcome hemi...must be a mopar guy.

Thanks for response and welcome. I called Miller and they would not give me the schematic, said either the PCB is still in production or something relevant. Definitely MOPAR guy (1970 Coronet R/T). Hoping someone in here or a Miller tech may see and send it. Thanks again.

Keep a watch on ebay. I scored a tech manual for my Trailblazer there. Not common, but it does happen. ...and Welcome!

There's a tech manual on eBay now. May not match your ser no but might be close enough to be some help. There is also a new circuit board on there now.

Thank you for your input. That Technical Manual contains a basic block diagram schematic, not the control circuit board schematic. I have this manual. I will not buy a circuit board as I will fix mine with/without the schematic. Have been repairing electronic PCB's over 25 years.

Aeronca41, you may be right. I overlooked this is not an Owner's manual but a Technical Manual. I will contact the seller to see if the control PCB schematic is included. Thanks!

Generally the Tech Manuals do have schematics; owners' Manuals, as you say, have rather useless block diagrams which aren't much help for component level repair. Hope this works out for you.

I hear you on fixes. I've been fixing things to the component level for 50+ years, up to and including mainframe computers, and find it very frustrating when I have to end up drawing my own schematics from the boards. That, of course, has become increasingly impossible with everything integrated into processor chips or gate arrays now, not to mention no longer having access to the necessary surface mount and hot air soldering equipment since retiring. Good luck.

50+ years?!!<br />

...I didn't realize they had electricity back then...

[Aeronca41]

Yeah-you had to make it yourself by rubbing a cats back with some high-dielectric strength cloth-and the cat usually didn't like it. :-)

hemi-did you get any info on that manual? I'm thinking it will be what you need.

They caught lightning bolts and kept them in a hair lined bag with a tiny,tiny hole so only a little got out at a time. That was later than the rubbing the cat thing. You've heard the saying "Letting the cat out of the bag." That's where it comes from.

[ryanjones2150]

Holy smokes! I never knew....

[Aeronca41]

See you just never know what you might learn from all the brilliant minds here!

Meltedmetal, that was just great!

Sorry, hemi, we know you're trying to be serious here. Don't mind us.

[ryanjones2150]

Ya man, sorry. If these guys here can't help you get this thing figured out, it probably can't be figured out. There's a lot of knowledge on this bunch, myself excluded. I bet somebody here knows where Jimmy Hoffa is.
