I've had our Miata conversion on the road for close to 5 years. Sunday it died. Both the "run" light (alternator) and the "error" light (check engine) are lit on the dash. There was no telltale popping noise and all wires, cables, batteries looked fine. I towed it home and put my laptop on the serial port and...nothing. No communications whatsoever. On the hairball, the yellow "Contactor Off" LED is lit, but the green "Contactor On", "Precharging" or "Error" LEDs never light.
Since the serial port was working before and the LEDs indicate no processing, my thought is that the hairball croaked.
Anybody have a similar issue or thoughts to share?
