A series of unfortunate events

It has been a while since I have posted and many might think it is because I am driving ERX everyday and reveling in the success of this incredible project. Unfortunately, that is not the case. The main reason I have not posted in a while is it was the holidays and I had many family events on the weekends which limit my time with the car. And, THE SEATTLE SEAHAWKS ARE SUPER BOWL CHAMPIONS!! OK, back on topic. I do not have charging set up at home yet. I rent a house and have not worked it out with the landlord to get an electrician in to run the line and install the outlet. The outlet in the garage has a 15 amp breaker on it and is also tied to the lights in the house. My charger trips that breaker since it pulls about 14 amps continuous from the wall. So, I am limited to charging on the weekend using a long extension cord running out of my daughter's room and therefore, not much driving of the EV has occurred.

I am also getting frustrated with the car. This blog has detailed the long process this has been for me and it just keeps getting longer. One evening I went to pick up my daughter from a friend's house and decided to take ERX. All was fine until I hit a speed bump at 35 mph. I did not know it was there since I do not drive that road often and the headlights on the car, although adequate, are not quite as bright as I would like. It did not help that my ride height in the front of the car is a little low and I have been very careful around bumps and intersections since I have not had time to adjust it. I believe this speed bump jolted the motor/adapter plate slightly, and it is misaligned just a bit now. The reason I have come to this conclusion is I hear a high pitch metallic rubbing sound when I release the throttle. I had a similar experience with my first motor/transmission coupler, but the sound was slightly different. That coupler broke and the input shaft bearing also got shredded. I am concerned I am putting strain on the input bearing to the tranny again and do not want to have to take it out and replace it for a second time, so I will need to remove the control board, hoist the motor slightly and loosen the nuts on the adapter plate. Then, wiggle the motor around a bit, give it 12 volts or so and see if I can get the sound to go away. If I can get it to stop, then I just need to tighten the adapter plate bolts and check again with 12 volts to see if it is properly aligned while re-tightened. This is causing me a lot of frustration for a couple reasons. The first is, the adapter plate and coupler I originally bought were wrong, then new ones were sent, but the adapter plate was still off, so I adjusted some of the mounting holes. Now the extra space in those holes may have allowed the motor alignment to slip. The coupler I received failed and I had a friend make a new one which I believe is working well. All of this headache would not be occurring had I received a properly machined adapter plate and coupler that fit my transmission. I would like to go back to Evolve Electrics and ask to see if I can get the adapter plate and coupler replaced for free, but I purchased my parts over 3 years ago and am not sure if I will get anywhere with them or if it is even worth my time.

Next frustration. I have two battery boxes in the hatch area of the car. I cut holes in the floor to sink the boxes down to keep the weight low and leave space in the hatch for cargo eventually. A friend made 1" angle iron frames to bolt to the car and then my boxes have lips on the top that hang on the angle iron frame.  The angle iron frames fit very snugly against the hatch floor, and I have come to discover that snug is not good. Every little bump in the road causes loud metal on metal scraping sounds and drives me crazy, so this last weekend I decided to attempt to remedy the situation. I removed all the batteries from the rear boxes, and removed the boxes and frames. I got the angle grinder out and cut the hatch floor a little more in spots that the frame was rubbing. I had some old bicycle tubes and decided to cut some pieces to put in between the frames and the hatch floor as well as between the frames and the boxes. This took some trial and error, but I completed the smaller, rear most box as well as trimmed the hatch floor for the larger box. It took me about 6 hours though and a lot of climbing in and out and checking and re-checking. In a couple weeks I will get back out to the garage and try to finish up the large box. This was all very tiresome and because I am already frustrated about the motor alignment, which still needs to be addressed, I finished the day wondering whether this was still worth it.

When do the care-free commute days start? When can I tell my wife that the war with the car is over and now I can just enjoy it and spend more time with the family? How many times am I going to have to tear the car down to fix something? Once I adjust the adapter plate and motor, will it stay put and last for a decent period of time before I have to fix it? How many more weekends is it going to take for me to finish this thing? As it is, I only work on it about every other weekend for about 6 hours. Some days, like Monday, I wonder if I should just sell the car and move on. I have been to this point once before and almost did sell it. I realize I am just venting here and am not really trying to discourage people from this type of project, but it may help me get past this "speed bump" and keep motivated to finish the job. If I were to give any advice, and maybe I have written this already, but I would say to make sure it is the right time of your life and you have the 500 hours or more available to do the job before starting. I got married 4 years ago, moved 3 years ago and had a baby 2 years ago along with raising a 15 year old as well. This was not the right time of my life for this, but at the time I started it, I was obsessed with the idea and a bit ignorant to the amount of time, expertise, and dedication it takes to complete this project. The thought of selling and taking the money and paying off some debt or putting a down payment on a Leaf, Volt, or dare I dream, a Model S or X is very tempting. I know that once I get the car to the point of daily drivability I will be very proud and have a very unique item. It is just hard to see past these troubles right now.

Thank you, in advance, for the encouragement I am sure I will receive after posting this.
