He said it’d be $50 for s recalibration. But he also sent me a link with instructions on how to recalibrate it yourself using a 12v source and a car battery charger. The instructions are a little vague for me. But I think it’s saying once you hook it up to the power and charger the needle should read 1,800. If it doesn’t I guess you set it to 1,800 while it’s powered up, and I guess tje needle will fall to zero once the power is disconnected and it’s recalibrated?
The rigging up of the equipment looks like a little more electrical than I wanna do. It doesn’t look bad really, but $50 to have someone else do it doesn’t sound too awful. https://websites.godaddy.com/blob/19...9.pdf?2089e5c1
That’s pretty much the procedure. I emailed asking about it and the guy emailed me back.
Hook it up set it to 1,800 and unhook it.
I’ve never really studied the tach this well before. Well there are four hash marks between each number. What does that mean, that each mark equals 200 rpm?
I never really paid attention to how many hashes there were until now so I always assumed that the line above the 1 equaled 1,100. I’m guessing the hash marks are more for aesthetics than accuracy.
Which hash mark would y’all say would be 1,800?
