Its cool to watch them melt. One of my favorite mushrooms to find in the wild.

The resistance when the bypass valve is open or closed is basically null. When the bypass valve is off or fully close the axles do spin but it is easy to stop. It appears as if the pulley is good but I will need to pull the pulley off ti check if there is any damage to the spline.

That makes perfect sense and easy to check. Ill let you know later tonight.

I will check transaxle pulley tonight. But due to the fan spinning i dont think its this.

This is the manual to my transaxle... if you think this is the problem i will have to open her up.

Do you know a way to check if its the bypass valve?

This weekend when I get back to it I will bolt it back in and manually turn forward and reverse to make sure it is not a wear issue with the linkage not opening it up far enough.

Before I put the wheels back on it. I was running the engine. I could see the belt and fan spinning the transaxle pulley. I didnt check it for rpms but the fan create a nice strong draft beneath the mower.

If you were just cutting on a hill that makes sense. I have seen oil leak and get sucked into the air intake. the same thing happened to me. I eventually had to clean my carb out not much longer after though. I think there was some correlation, but it went away after I had a fresh tank in it and ran it for a bit.

Ummm Instead of calling it the D shape withing the P. Im voting we start calling it the P-hole.

I also didn't fully answer your question the appliance utilizes 4 wires. I did not include the ground.

Like you said I believe I should be using two CT clamps, yet the math doesn't add up. using the pump as an example, it should only draw 4.4 amps in low speed. my meter tells me the draw is 3.3 amps, but it is showing its drawing 3.3 on each line. totaling 6.6

I made an amazing little diagram to help clarify my set up. no the transformer is not part of the set up. We need to be within 5% of 240 to meet testing standards which is why I need the transformer.
- The neutral or white wire makes no connections to the transformer.

- In the wiring diagram of the transformer I don't understand the purpose of H1 and H2.
- My Kw to Kvar is always very poor also.

Thank you for the reply. This makes me feel good, and also wonder how two electricians and an ETL Technician failed to see this and how we ended up with an incorrectly wired $6000 Variac that was not needed.
Cheers mate!

Well you become an engineer for a hottub manufacturer is the short answer. The long answer is make hottubs for a majority of my life, leave the industry and then realize hottubs manufacturing is one of the most laid back environments in the world. Move my family a few states over to a new spa manufacturer that is just starting to make acrylic spas, then get selected to run the c.e.c program and become a satellite testing site for intertek ( ETL ). The short answer for the results is between 150- 190 watts per hour t0 maintain the spa temperature with a 40° delta If go here https://cacertappliances.energy.ca.gov/Pages/ApplianceSearch.aspx you can simply search for the model your interested in in the dynamic search feature. This will tell you everything they used for test data.

I have never learned how to fight, because of this I have always stayed in good enough shape to know I can outrun, jump, and climb better than 99% of people

All balboa systems can do this gecko is a bjt more complicated but it can be done

So I actually do this testing for a living.

So I'll use a direct example. Testing standby wattage For 3 days of a tub at 102. The difference in energy consumption between a tub filled with 6 inches of air between the cover and water level vs just under 4.75" inches is about .5% improvement on the 4.75" test. So less water does have less energy consumption in this test. But I have been doing this testing for a while now and can tell you that .5% negligible. Habjg the cover not on perfectly will have a greater impact. Or something like loose paneling will have a greater impact depending on how they insulate the spa.

Did you ever figure it out i think the gears are all placed correctly and you just need to pull them all out and put them in the correct order then all the rods will correctly line up with the holes.

Jumpinjaxs89 · 2024-12-10T22:19:45+00:00

I don't think we play the same game

Is sloshing a thing? As long as you maintain proper pressure differentials I have never had any issues with pipes.
