So I was having a problem getting the 10,000 RPM tachometer LEDs to show up on
video and what I didn't mention was that the needle would start twitching above
4,000 RPMs and would become very difficult to read. I have been addressing these
issues over the weeks and luckily for me I managed to sort out both problems.
The twitchy RPM needle turned out to be an issue with my ignition coil which I
estimate to have many many hours on. It was basically a last ditch effort to get the
tach to work properly & accurately above 4,000 RPMs. I first tried to remember what
ignition coil the engine had and where I got it from. It came from a seized engine I
bought off of ebay and yes I knew it was seized before buying. It powered a vacuum
bag attachment for a riding lawn mower. This thing looks horrible and so much so I
thought I should post a picture.
The video problem I was experiencing was solved merely by luck and me lacking the
patience to wait for tomorrow. Late in the afternoon I decided to test the tachometer
once more using a nearly new ignition coil I keep for spares. I guess I didn't
want to waste another complete day for something that couldn't be helped. During testing, I was so impressed with the performance of the tachometer with the new ignition coil that I pulled out my phone to try once again & capture a video. It isn’t the most stunning video, but both the needle and numbers were captured easily. After uploading the video I convinced myself that the reason it was filmed properly was because of a reduction in sunlight reflecting off the driveway.
