Display happy again
I found the problem which was causing my display not to display serial stuff. Turned out to be the PCB header/connector for the serial info that I have used on the board.
It only has a finite number of plugs & unplugs & after that the connections become a bit erratic. Got a new one coming along with the bits to make up the charging monitor & some new mosfet clamps for the controller.
Will be OK once I stop unplugging the display 57 times a day to fiddle with it.
I seem to have the tacho bit sorted out now too although I had to resort to Plan B. I fitted the guts of an aftermarket SAAS tacho onto the VW dash panel after I removed the original drive setup. Fitted very nicely & even the spindle was the right diameter.
I had to use a Digital Speedo Corrector kit that I had lying around (also works on tachos) to get the tacho to read right because the SAAS scale & the VW scale were about 12% different.
I have the bits coming to get the fuel gauge working via the display & an LM2917 to hopefully make the temp gauge work like a battery amp gauge.
