Hey guys,
I just got a 1971 240z on friday as a car to work on. So far I have fixed a broken front headlight, seatbelts, interior lights, door locks, and the windshield wipers.
But yesterday I got pulled over for speeding and got lucky with a warning. I want to fix this speedometer next. I'm only 16 years old, I have ordered "How to Restore a Datsun 240z" and the Haynes service manual but I would like to know what to look for and troubleshoot to fix the speedometer.
As for the Tachometer, I don't know if I can still use the factory gauge because the previous owner installed an MSD electronic ignition system. A local 240z mechanic told me that the stock tachometer cannot accept the new ignition system, and that the tach has to be electrical not mechanical. Is there any truth to this?
Forgive my ignorance, I am only 16 and still learning. I plan on reading both books from start to finish as soon as I receive them, and as soon as I become a senior w/ half days, I plan on taking some automotive classes at the local community college.
Thanks in advance,
-Armand
