Working ?

I think I connected the 12V lead this time, and its all connected together. I expected the battery status indicator to always be "full" for the first 10 - 20 miles, but I got a "battery low" red light after 6 miles.

I'll do a real charge and drive tomorrow. Here are the photos from the install.

interesting Observation

While the LED Lights aren't working on the Enginer panel switch, when I press the button to ON while driving, the Prius MFD display says " Cannot enter EV Mode at this Time". This tells me two of the three wires I connected under the dash must be connected properly.

My problem seems to be the connection to the 12V lead.

Day Two - Still not long enough!

After charging (I think) the batteries overnight, John and I installed the unit in the trunk, and began to test operation. John re-assembled the undercarriage covers, etc. so that I could drive the car if needed.

I was able to see the car operating normally with the new kit disconnected. Unfortunately, the lights from the new switch were not lighting. Something was wrong.

I verified as best I understood the wiring connecting to the car's ECU connector. Still no lights.

I connected to power output from the kit to the drive battery, and I got a error warning from the car's computer. I looked at the connectors to the drive battery, and compared them to the instructions. Molded on the Toyota terminal were little + and - symbols, exactly reverse of what the instructions indicated. So, I re- wired according to the instructions.

Trying again I still had no lights on the switch. I don't know what is wrong. My best guess is the wiring at the ECU isn't making a good connection, or the instructions were wrong / mis- understood by me.

I have a trip to NYC, and won't be back to continue diagnosing until Friday at the earliest.

Sadness.

Day one - Long, but not long enough!

I began the actual conversion at 12:30 yesterday. The documentation, including the video, were weak. I was helped for part of the time by my friend, John Steigauf. His auto mechanical knowledge was most helpful!

By about 6:00, we were ready to put the unit into the trunk, and bolt it in. The dashboard cables were run, the power connectors to the drive battery connected. It was a good time to rest.

Install Fest Scheduled!

This coming Saturday, I'll get together a few friends and actually install the Enginer 4K system!

Look for lots of Pictures and videos after.
