Looking For A Parts Diagram For A Emglo LAG8HGA-8P--Trying To Find The Regulator--Not Like The Ones I See On Emglo's Parts List. This Is A All In One Unit The With The Air Gauges On Each Side Of The Regulator.

I just rebuilt my Emglo AM78 4CHV, new pressure switch, unloaded, check valve, aftercooler, and changed the #30 oil, It takes 4oz.
Runs like new after not cutting in/out correctly and purging air before reaching 125 psi. Kicked it down to 115 max psi via main spring setting. Don't need 125 for trim nailing and siding.
FYI don't use cheaper generic 125 psi pressure switch from Amazon!!
use Jenny M4-1247 (140-1074-01)

Hello Brenden,
Did you find the value for r13 on the Mobitronics MPS-50A power supply?
I am looking for that value also.
I cannot locate where R13 is on the board so if you give me some direction I may be able to help.
I do not have a diagram just a power supply that I am trying to repair also.
Cheers

If no damaged wiring is found, it's most likely an internal fault in the ECM (Engine control module, computer, PCM, ECU, whatever you want to call it, it goes by many names)
The Voltage Regulator is built into the ECM on virtually every Chrysler product (including Jeeps) after 1987 or so. And it is prone to failure. If it does fail, you either have to replace the ECM or install an External Chrysler Voltage Regulator, which requires some wiring harness modifications and a few parts that can be purchased at your favorite auto parts store.
To do the External conversion, you'll need :
1 Chrysler Voltage Regulator (virtually any Dodge/Plymouth from 1970 - 1986. It's best to order one for a 70's 4x4 Truck with a 318 engine though, to avoid any possible mix ups)
1 Chrysler Voltage Regulator Pigtail (this is the plug that connects to the regulator)
Roughly 10 feet of 14 gauge wire, possibly less, depending on where you want to mount the regulator.
Most, if not all Regulators now include a wiring diagram in the box, for this purpose, just follow the diagram and match up the field wires on the alternator with the ones in the diagram. On a '93 Jeep one field wire should be Blue, the other should be Green.

There realy isn't a 'wiring diagram' for this engine. Are you looking for an 'illustrated parts list' perhaps? If so, go to ... http://www.partstree.com/parts/.... scroll down to Engines, click on Briggs and Stratton, then enter the model # and type # on the left. Leave out the word 'TYPE'... just put a - between the model, type and trim numbers. The parts are available anywhere. This site is just a good reference for mowers and engines diagrams..Hope that helps.........

Hi Pete,
On the side of the motor on the label should be a wiring diagram. The diagram will tell you how to wire fro high 220v and low 110v ...
If the nameplate is single voltage only then the motor cannot be rewired for the lower voltage...
Also check the motor RPM nameplate as compared to the others...you may have a 1725 motor and the newer ones a 3450 motor...that would give them double the RPM's if the gearing or pulley sizes are the same...so.. if you have the right voltage and the RPM's of the motor are the lower, then you possibly could change the pulley sizes to speed up the compressor...

Lots to check and think about...

I would suggest contacting Master Tool Repair, great web site to get information on these little machines, I know you can get owner manuals from them that may contain wiring diagrams with them.

Manual for the similar dewalt model is at www.dewalt.com, click on parts & service icon, then enter D55151. Or try clicking here: http://www.dewaltservicenet.com/documents/English/Instruction%20Manual/5135175-01,D55152,Elec.pdf This Dewalt compressor is one of many versions of the Old Emglo AM78 compressor. There are several other brands built with the exact same design such as the Senco line. For parts list of actual Am78hc4v go to mastertoolrepair.com. If you have questions or problems with this compressor please email, Good luck
