In August 2017 I changed from DC drive to AC. Since then I have had no real issues to report. I have added Air Suspension, a new DC-DC converter and a GSM switch to remotely control the cabin heater by text messages. I haven't updated the blog since 2018. I have just been pretty much trouble free driving since then. It is coming up on the 12th anniversary of the conversion start and 11 years of being road legal. Now this year is "operation tidy up". Over the years I have tried many different systems and basically replaced everything at least twice. Apart from the Air Suspension I have been driving the same system of AC drive for the last 4 years.
I still have exposed battery terminals in the rear trunk of 'sparky', so I have made a CAD (Computer Aided Design) drawing of a battery link cover that will prevent accidental shorts (none so far) and any risk of shock (only minor tingles so far). I shall 3D print these in Vivid Orange PETG plastic. I have had a 3D printer for just over a year now and it was one of the best Christmas presents ever. I knew nothing really. I had no experience with CAD drawing and no experience with 3D printing, but I knew what it was all capable of. I taught myself CAD in about 2 weeks. I have now learned the basics on 2 different CAD software. I have learned enough to make some fairly decent boxes, brackets and covers as well as the art that I have printed using my own designs (that's another hobby altogether). The pictures below show the battery link cover from 2 different angles. I shall print them upside down, so on the bottom (top) is 2 recessed symbols for '+' and '-' the I shall fill with paint (red for '+' and black for '-').
