It's not related to the quad mod. That mod just protects the Quad winding from getting damaged should the voltage regulator fail. The MOV mod helps protect the voltage regulator from failing due to voltage spikes from the quad winding causing the diodes in the regulator to short out. When I...

For those interested... I found that the Walker 40001 is a perfect fit for the the MEP-831A exhaust. Bought a 25' length of it and made a flexible exhaust extension so I can run my 831 inside the "warm" garage and vent the exhaust out one of the garage windows while I'm developing and testing...

Last few fuse holders and fuses I bought off of eBay. If you need a MOV or two I can mail you them. No charge.

Always glad to help. Now on to fixing the next one!

With no Faults, Battleshort OFF, set running S5-4, S5-5 and S5-6 should be at 0 volts and S5-2 should be at 24 volts. The coil terminals of K1 (the unlabelled ones) should both be at 24 volts. When you toggle S5 to CLOSE and hold it there S5-4, S5-5 and S5-6 should still be at 0 volts and S5-2...

The MOV would have no impact on the battery charging rate. After each start it's normal to have it up in the green and then slowly drop back to near zero after the set has run and the batteries get recharged after being drawn down some by starting the set.

The -10 TM suggests letting the set warm up for 5 minutes. From the TM... Under normal conditions warm up the engine without load for five minutes. (If required, load can be applied immediately.)

No. In the current firmware build the controller defaults to the Aux Fuel pump to be OFF at each start regardless if it is started via WiFi or 2-Wire. To enable the Aux Fuel pump the gui must be used to enable the Aux Fuel pump after each start. This is to prevent the Aux Fuel pump from...

Had that happen 2 years ago. Just got the bird in and lights out. The 802 happily ran the oven and the rest of the house that Thanksgiving.

You'll have to take engine/muffler vibration into consideration. Connecting hard pipe directly to the outlet may lead to the muffler cracking. If it were me I'd look into using some 1 1/4 ID flexible exhaust pipe to do the extension. That or use a short flexible exhaust hose between the muffler...

I happen to have my 831 apart and got the measurements for you. The pipe is 1.250" OD and 1.140" ID. The pipe is cut at an angle. This is what it looks like once you get the cover off and the rubber hose nipple off of the exhaust pipe from the muffler.

I have 3" casters on both of my 831A's. Picked them up at Harbor Fright. They work very well for moving them about the garage & driveway.

Any fault light when it shuts down?

O'Reilly Auto parts lists it but the pics don't show the juggler for bleeding the air.

Could be the batteries are bad and the 831s charger can't put out enough current to bring the voltage up and run the pump. Another possibility is the charger may not be working. Check the fuse in the control cube. It is in the power feed from the PMA to the charger.

Looks like the Freq Meter is a 200 micro amp AC current meter. So at 60 hz it looks like the current from transducer should be 100 microamps. The -24 TM has test procedures for the transducer and the meter.

The Frequency Transducer A7 gets it's input from S8 the reconnection switch inside the control cube. It picks up L3 & L0 from there.

Yes All of the times for Pre-heat, Priming, Cranking, warm up and Cool down are all user settable. Different time delays can be set for WiFi start/stop and 2-wire start/stop. The Pre-heat only occurs when the temperature is below 40F. The controller has a temperature sensor to determine if a...

Which 803 "Control Board" are you referring to? I offer a Control Board that provides 2 wire Start/Stop capability to work with an ATS and other systems.

Also try reconnecting the white plug in the wires to the actuator. Then start it normally. When running the LED in the righthand relay in the control cube should be illuminated. Then move the master switch S1 to OFF. The LED in the right hand relay should go out. Does it?
