Hi all,
wanted to ask a few questions before spending time on this and I know tach questions are old
Does anyone know what typically fries on the tachometer circuit board? I pulled gauge out of the dash and wired it directly to the battery and the dist *with and without the filter* and alas all it does is turn all the way to the six o clock position and nothing else. So I took a cheap meter just in case didn't want to blow my fluke up and hooked it up to the dist output on the dist. put it on 500v and was getting a 11/12 changing back and forth reading but not in a true pattern. so then i put the filter on and got nothing on the other side. both with it bolted to a chasis ground and not. so here are a few questions.
Does the Tach filter need to be bolted to a chasis ground?
How do you test the tach filter?
Does anyone know what goes bad typically on the tach board?
Anyone have a factory tach for sale or know where I can find one?
Thanks a million
