I was able to get the car to charge. The quick fix was that I replaced the power converter module on top of the inverter/motor. It was about 4 hours of work. I got an entire EM57 drive unit for $710 (Morris Rose carparts Kalamazoo Mi) and swapped only the power converter. charges great! it has a...

I was measuring the voltage levels at the chips outlined above. the NAND gate has 11vdc between VCC and ground. then I plug in my most powerful charger and it blows a AC power fuse, a 56amp thru-hole one on the AC input board. the fuse was good before, but not now. I also remove the bridge...

Thank you for the response! I'm not the only one with this fault and it may crop up more. so it's good to understand the problem before towing it to the dealer and/or throwing parts at it. its -10vdc on the CP line the entire time the handle is in the plug. the PP line is 1.5-2.5 volts...

OK, so I took off the lid of the power unit and traced the control pilot and proximity pilot lines to the PCB on the front passenger side of the unit. after the conformal coating was removed, I followed the traces on the PCB to several ICs and also found that there is the correct 2.74kohm...

Is there an update on this? I now have a 2015 leaf and it is on low-low battery. no quick charge. upon insertion of several different 120 and 240 OEM and aftermarket known good EVSEs, the passenger side blue light blinks for 1 minute, same as OP, and it draws 0.5amp then it stops charging. the...

I am researching a similar idea to make a split heat pump heater for DHW and also my spa, both which are now NG. according to one single youtuber guy who made his own split DHW tank claims that the indoor unit is nothing more than a length of pipe. So a plate/plate exchanger or your A coil would...

I bought (NANKANG SP-9 CROSS SPORT P205/55R16) for my 2012 from Walmart. half the price of OEM tires and I did not see a reduction in MPGe.

The Mr. cool DIY 2/3-ton ducted split that we are talking about looks like the go-to model for furnace replacement. considering that a traditional 95% AFUE + 13 seer aircon is going to run $9k+ from a HVAC place, the Mr. Cool DIY is starting from a great cost position. I found someone who did...

I still use a $15 heated blanket in the winter, I also use a 12v defroster to keep the window from fogging. To run both at the same time I had to add a supplemental key-switched, fuse protected power outlet as both items will exceed the stock fuse. search my posts to see it. I've got a 33 mile...

I have seen that there are two groups of IR remotes, one way and two way. bassically the remote is smart or not. for a window AC unit I previously had installed a Broadlink WIFI IR remote that is smart and phone controlled. maybe that will control better...

This brings up a great point. All the fancy HVAC equipment in the world cannot help if the controls are ugly. There is an XKCD out there showing the digital resource lifespan. (https://xkcd.com/1909/) In a not joking way these Asian-made, WIFI connected devices won't be supported for ever and...

I wanted to share my recent installation on a 12,000BTU mini-split in my two story, 2200sqft house. It was always part of my plan to install this with my off-grid solar, but it took 2 years to get it done. The trick is that I installed it in the stairwell between the first and second floor, one...

The first step is to see if there is continuity between either line and ground. Next pull of the covers on the outlet and inspect what you can. Is it aluminum or copper wire? Since it happened after some time it could be those fat wires growing a little and making contact on a sharp edge.

If it would help, I made a post about how to automate this same exact evse board with an Arduino microcontroller in a different post. My program, which I link to in the post, is intuitive. It 'looks' at the LEDs to see what amps it is set at, then 'presses' the button to change the charge amps...

I'm not sure vehicle to grid is ever going to take off. The industry has had lots of time to think about it and make a business case, and nobody's done it commercially in the USA. I think the reason is that electricity in a vehicle battery is much more valuable than it may seem, its priced in...

That's right, factories have to pay for reactive power, so they try to add PFC to keep their bill down. residential users get reactive power for *almost* free, however off grid, I need to make it myself. adding capacitors inside of each appliance (switched with the load) is OK, but they don't...

Just saw this news article that the Texas legislator has bundled winterization goals, which are good, to fees on renewables. thoughts? https://www.houstonchronicle.com/politics/texas/article/Texas-Senate-passes-bill-aiming-to-counter-16062267.php "State Sen. Charles Schwertner, R-Georgetown...

In the planning phase it might helpful to not look at the real power, which is the nameplate values on motors etc, but instead the apparent power of your appliances. as you may know, apparent power is 'real' power plus 'reactive' power, or real power divided by the power factor. with grid-tie...

I think the 2021 texas power outage was one more fork in the road, some people said it was proof that they need more fossil power, others that more renewable was needed. And there are examples of individuals reacting in both ways for each camp to point to, some people with the new ford F150 with...

danrjones, Thanks for sharing this current pricing information, can you please clarify if these are generation cost or if this is an out the door price? I did not appreciate the costs that you had to deal with and I can see why it’s worth a lot of effort from you to mitigate a possible $0.61/KWH...
