Hi,
I have a very rare fibreglass car based on a 1991 Nissan 200sx 1800cc. It has been put away for the winter, during which time I installed a much more powerful battery. Now that I have just put it back on the road, I have found that the digital speedo, mechanical odometer, mechanical trip meter and digital head up display do not work at all.
I'm hoping that someone far more knowledgeable than me can diagnose my problem.
Many thanks.
