How hard is it to install a Tachometer? I know I don't really need one, since my car has a C4, but I think it would be good to have on anyways. How hard are they to install, wire up? How do they install, and heres a good question... how do they work?
Thanks alot.
Not hard at all. There will be 4 wires: 2 to the coil, one for the instrument lighting, and a ground (IIRC, been a while since I installed a tach). It works by sensing the firing of the coil.
possibly the polarity was reversed on it, possibly caused by hooking the tach leads up to the wrong terminals? though i would have thought that it would just burn out if hooked up wrong. thats weird.
