I think Ike has it figured out. Running the house on L1 / L2 with a frame ground on the generator will work fine. You automatically get the ground reference by making a connection to the neutral (bonded to ground) at the house. Phantom voltage sounds correct based on your findings. Different...

Yes, confirm the correct number of flex plates prior to assembly. If one required then three is a likely problem. If three required then good possibility it will be just fine when re-assembled.

The bolt at 11:00 O'clock shows markings of fatigue indicating that at least that one bolt did not fail suddenly but rather developed a hairline crack and propogated. IF what I see is the bolt surface and not the tapped hole. I think this is a fatigue failure. The bearing could have been bad...

I wonder if the wrong grade bolts were used or if not tightened properly, or maybe anti-sieze or some other thread compound was used where it should not have been. The alignment is determined by the machining of the parts in these single beraing generators so it is unlikely there is an...

60vac from L0 to L1 or L2 in the 120 vac single mode is normal. Before connecting the generator to a home you need to know how the generator output is grounded to the frame. Measure the voltage between L0, L1, L2 and L3 each to the frame ground on the generator. The generator is fully...

I'm not at home now but I think it is a M12 x 1.5 nut. I know it was a metric lugnut I got at an auto parts store.

Time to pull the nozzle and pop test it. The pop off pressure is listed in the manual. Tips cost about $80 including new shims adjust pressure, clean, re-blacken holder and test. A new injector, essentiall. The pop pressure is somewhere around 2,400 - 2,600 but don't quote me. IF the...

Fixing the Hz gage: The gage itself is an ammeter that is set for full scale reading at 200 micro amps. This can be tested by an electronics shop or anyone that can put the tiny 200 micro amp load on it. The gage is usually not the problem. The transducer is the black box that is about 3x3x3...

I think it is 4HN. Check my threads I have converted many to use (2) 12 volt lawn and garden batteries. Requires fabricating a new tray and top hold down device.

Right on, Ike. Each machine must be inspected to see how it is wired in order to fully answer the question. The machines as designed are fully floating meaning none of the generator outputs are grounded internally. The manual is written for this instance and calls for grounding the L2 for both...

Yes, exactly. Do you think you might try it?

Not to rain on the parade but working through the physics of it on the flipside when the load is applied and it does speed down then the same amount of power with a larger flywheel will take longer to recover speed. In essence the flywheel will only increase the time response it will not...

long post Just my two cents here. And maybe because I'm an engine guy more so than a generator guru. Gen and engine are obviously two separate components each with their limitations. Which ever is the weak link determines the overall limit of the generator set as a whole. Personally, I would...

Ike, That Walbro looks good. Derf, The 802A uses two of the cube type. One for primary and one for the Aux fuel function.

Ike, Can you post up a pic of the walbro? thanks, Doug

Ike, I have not seen a walbro on anything. walbro is a large name and does supply some oem to car companies. The Yanmar only needs a good gravity feed so any pump that can get the fuel there is good enough. Is the Walbro 24 volts? Following are some pics of the battery tray installed on a...

To bypass the solenoid at the fuel lever you may remove the little L bracket that prevents the throttle lever from latching. To adjust the set speed when using the latching lever loosten the two bolts that hold the throttle lever to the engine case. the left bolt is a pivot bolt, the right one...

Well the wholesale swap of the entire A1V1 regulator did seem to fix it. However, I will keep running it when I get a chance to make certain. Are the capacitors you refer to the ones in the regulator's board or others bolted directly inside the control box to the walls of the box? It looks...

The stuff below the fuel filter is as follows: 2 small identical relays side by side are for the grid heaters. All incoming and outgoinjg wires are split so each relay coil and relay contact sees half the load. Strange. The large cylindrical unit with the hoses is the primary fuel pump that...

I've been runniing a 701A and have noticed that after about 10 - 15 minutes of running the output voltage drops off. Starts out around 120 when the knob is cranked almost fully clockwise. Then, as it warms up the voltage drops off until it gets to around 106 or 108 at full clockwise on the...
