I see in the pics and videos that somewhere in it's life someone cut the safety wires off the two mechanical governor adjustments. Not good... Those are adjusted at the factory and normally would not ever be messed with. Someone messed with those adjustments. In the short video the governor...

You may want to carefully verify the DCS is being provided +24 volts to the P2 plug on the back of the DCS. B+ pins should have +24 volts on them.

Check the fuse in the fuse/relay box to be sure the one for the DCS is there and good and that all the connectors to the fuse/relay box are connected.

Pretty close. Here is a link to a post I did a while back with waveforms from various MEP generators. Waveforms

Here are some waveforms I took of both my local utility power and of my 1030 under a 60% load. Utility Power 2.4% THD My 1030 Under 60% Load 2.6% THD

The Frequency gauge is a Current meter, not a Voltmeter. It's a 0-200 microamp gauge. So to display 60 Hz it would be supplied with 100 microamps from the frequency transducer.

Git it. Will email in a bit.

I'd say the A1 AC Voltage Regulator is bad based on your readings.

That is a surge suppressor for the solenoid on the starter. It's there to suppress voltage spikes from the starter solenoid when the starter is disengaged. It's likely there to protect the DCS from damage. Be sure to get it hooked back up otherwise you risk damaging your DCS.

This #15?

That wire in your picture is item 4 below. Its a wire assembly with a diode inside the heat shrink. It has to be installed with the correct polarity!

Looks like the DCS monitors the AC Voltage at K1-A1, K1-B1 & K1-C1 to monitor the gen head output voltage referred to as the GENSET Voltages. I'd assume the DCS uses the GENSET Voltages as inputs to the AC Voltage Regulator system in the DCS. The DCS also monitors the AC Voltages at the output...

That's the usual failure mode/symptom of a bad CR1. With no load it'll supply 24 volts. As soon as a load is applied the voltage drops to zero. Many have had that same symptom and failure of CR1. You're not alone!

It looks like CR1 is bad. To verify that put a jumper between the two leads of CR1 to bypass it. See if the generator crank properly. If so CR1 needs to be replaced. It's a 1N5406 3amp diode. They fail fairly frequently.

Has the generator produced power properly for you in the past? Generally that symptom indicates a failure in one or more of the AC Voltage Regulation system components. Those parts being: - A1 AC Voltage Regulator - T1 Transformer - R1 AC Voltage Adjust potentiometer on the front panel -...

Sound like you are losing power between MT4 and S1-3 Try the following 1) Put Dead Crank in the NORMAL position. 2) Put S1 in PRIME/RUN and verify the fuel pump is NOT running. Leave S1 in PRIME/RUN. 3) Check for 24 volts at both big terminals on MT4. 4) Check for 24 volts on BOTH leads of CR1...

Search MSP6729 3/8”x24 around $20. Another S.S. member purchased it for their 804. 804 MPU See post #7

Be aware the 804As were built with two different AC Voltage Regulation systems. Parts cannot be mixed between the systems. One was a "TRC" system and the other is a "LIBBY" system. There are 4 parts of each system that are unique to TRC and LIBBY. They are: - A1 AC Voltage Regulator - T1...
